==Birth Control: Mode of Action==
+
==Birth Controls==
-
*There are two categories of birth control
+
*There are two categories of birth control: contraception (prevent conception) and implant preventors.
-
*There are many options:
+
*Contraceptions include:

-
Why Counseling is Important
+
*The most commonly used birth control is tubal ligation making up nearly 50% of contraception use in "non-developed" countries.
-
+
===Barrier methods===
-
Abortion Rates, by age group, per 1000 births (2000 Stats)
+
*Barrier methods include: spermacides, condoms, diaphragms / cervical caps, and sponges
-
 
-
10% of women don’t use contraception –
 
-
These account for 53% of unintended pregnancies
 
 +
*Spermacides
 +
**The active ingredient of spermacides is '''nonoxynol 9''' or '''actoxynol-3'''.
 +
***Nonoxynol and actoxynol disrupt the spermatic cell membrane.
 +
**The failure rate of spermacides is '''15-35%'''.
 +
**Patient compliance is generally high.
 +
*Condoms
 +
**Male condom failure rate is 5-8% (slippage / breakage) or 5-15%
 +
**Female condom failure rate is 3% (slippage / breakage) or 5-15%
 +
**Mechanism of action is to physically block sperm.
-
+
*Diaphragms
 +
**Mechanism of action is to physically block sperm from gaining access to upper reproductive tract (uterus and fallopian tube.
 +
**Diaphragms can also hold spermicide.
 +
**Device must be inserted 1 hour before intercourse.
 +
**Diaphragm must remain in place for 6-8 hours post-coitus.
 +
**Failure rate is 10-25%
 +
**Benefits include:
 +
***'''Some protection agains STDs'''
 +
***Effective immediately
 +
***Does not affect breast feeding
 +
***Does not interfere with intercourse (can be inserted up to 6 hours pre-coitus).
 +
***No health risks.
 +
***No systemic side effects.
 +
**Contraindications include:
 +
***Hx of toxic shock syndrome
 +
***Allergy to rubber
 +
***Allergy to spermicides
 +
***Repeat UTIs
 +
***Uterine prolapse
 +
***Vaginal stenosis
 +
***Genital anomalies
 +
**Patient compliance is difficult

-
Unintended%20pregnancy
+
**Mechanism: contains spermicide
 +
**Benefits: small, disposible, works for 24 hours (regardless of coitus count)
 +
**Reintroduced to market in 2009.
 +
**Failure rate: 26-40%

===Hormonal contraceptives===
 +
*Hormonal contraceptives come as oral pills, as injectables, and as an intravaginal ring or a supradermal patch.
 +
*Injectable contraceptives include:
 +
**Combined injectible contraceptives (CICs)
 +
**Depo-provera
 +
**Norplant
 +
**Implanon
 +
====Oral contraceptive pills====
 +
*'''Failure rate is <1%'''
 +
*OCPs can be '''progesterone only''' or '''a combination of estrogen and progesterone''' (combined oral contraceptives; COCs).
-
+
*Oral contraceptive pills are taken 21 days with 7 days of placebo or no pill.
 +
*Combined oral contraceptives come in three types depending on their phase:
 +
**Monophasic: all 21 pills, all of which have some amount of estrogen / progesterone (E/P)
 +
**Biphasic: 21 active pills, 2 different combinations of E/P
 +
**Triphasic: 21 active pills, 3 different combinations of E/P
-
General Mode of Action
+
=====OCP mechanism of action=====
 +
*Presence of progesterone decreases FSH and LH levels, including the LH surge.
 +
*Without the LH surge, '''ovulation does not occur'''.
 +
*Furthermore the '''endometrial lining is ''thinner'' which makes implantation less likely'''.
 +
*The '''cervical lining is ''thickened'' which prevents spermatic penetration''' to the upper reproductive tract.
-
 
-
Prevention of Conception –
 
-
OCPs, Norplant, Depo-Provera, Condom, Diaphragm, Foam, Rhythm, IUDs
 
 +
=====OCP Benefits=====
 +
*Contraceptive benefits of OCP:
 +
**Highly effective (failure rate <1%)
 +
**Effective immediately if started by day 7 of menstrual cycle.
 +
**Pelvic examination not required to initiate use.
 +
**OCPs do not interfere with intercourse.
 +
**Few side effects.
 +
**Convenient and easy.
 +
**Client can stop use at any time.
 +
**Can be provided by trained medical staff.
 +
*Non-contraceptive benefits of OCP:
 +
**Decrease menstrual flow.
 +
**Decrease menstrual cramps.
 +
**Improve anemia (?).
 +
**'''Protect against ovarian and endometrial cancer.'''
 +
**'''Decrease bening breast disease and ovarian cysts.'''
 +
**'''Prevent ectopic pregnancy.'''
 +
**''Protect against some causes of pelvic inflammatory disease.''
-
 
-
Prevention of Implantation –
 
-
IUDs, “Morning After Pills” 
 
 +
=====OCP Effectiveness=====
 +
*Perfect use is what is tested but then there is actual or typical use.
 +
**OCP (combined versions) are 97% effective when taken perfectly.
 +
**OCP (combined versions) are 92% effective upon actual use.
 +
*10 million women are taking OCP; therefore each 1% decrease in effectiveness yields 100k unintended pregnancies
 +
**8% decrease simply from perfect use to typical use.
 +
=====OCP Contraindications=====
 +
*Absolute contraindications include:
 +
**History of vascular disease: pulmonary embolism, deep vein thrombosis, coronary vascular atherosclerosis
 +
**Systemic disease: lupus, chronic hypertension, liver disease, hypercholesterolemia, migraine headaches  ''with auras''.
 +
*Relative contraindications include:
 +
**Tobacco use
 +
**>35 yo
 +
**Depression
 +
**Seizures '''without auras'''
 +
====Injectables====
 +
*Mechanism of action:
 +
**Suppress ovulation
 +
**Thicken cervical mucosa
 +
**Thin endometrium

-
Worldwide Use of Contraceptive Types  
+
*Types of injectable birth controls include:
 +
**CICs (like OCPs)
 +
**Depo-Provera
 +
**Norplant
 +
**Implantation
-
 
-
Prevalence of Selected forms of Contraception in Developed and Developing Countries
 
-
+
*Failure rate for injectables:
-
Projected Use of Contraception in Developing Countries for 2000
+
**CICs: 0.1-1%
 +
**Depo-Provera: 0.1-0.6%
 +
**Norplant / Implanton: 0.2-0.6%
 +
*Injectable limitations
 +
**Side effects include: nausea, dizziness, breast tenderness, headaches, spotting, light bleeding
 +
**Effectiveness lowered in combination with other drugs
 +
**Can delay return to fertility
 +
**Serious side effects are possible
 +
**'''Do not protect against STDs'''
 +
**Change the menstrual bleeding pattern
 +
**User-dependent; that is, the client must return every 30 days.

-
+
==Intra-uterine Devices (IUD)==
-
Diaphragm & Cervical Caps
+
*'''Failure rate of 0.2-3%'''
-
 
-
Sponges
 
 +
*Mechanism of action '''can be contraceptive or abortive'''.
 +
**Interferes with sperm ability to travel through uterine cavity.
 +
**Thickens the cervical mucus.
 +
**Intereferes with reproductive process before ova can reach the uterine cavity.
 +
**Modifies the endometrial lining to decrease implantation.

-
Spermacides
 
-
+
*IUD contraindications
-
Active Ingredient –
+
**Pregnancy (risk of ectopic pregnancy)
-
Either Nonoxynol 9 or Actoxynol-3
+
**Unexplained vaginal bleeding
 +
**PID
 +
**Purulent discharge
 +
**Distorted uterine cavity
 +
**Malignment trophoblast disease

==Sterilization==
 +
*Sterilization is '''the most common method of birth control among married couples'''.
 +
*Sterilization is '''the most common method of birth control globally'''.
 +
*Only 1% regret sterilization.
 +
*'''Failure rate is 1-2% over 10 years'''
-
+
*10% of couples choosing sterilization choose vasectomy
-
Failure Rate –
+
**'''Failure rate of vasectomy is 0.1%'''
-
15 to 35%  
+
 +
==Miscellaneous==
 +
*Laction is a good birth control, too.
 +
**'''Lactation failure rate is 2% for the first 6th months'''.
 +
**Mechanism of action is disruption of GnRH release because of frequent, intense suckling at the nipple.
 +
**Disrupted GnRH means disrupted LH / FSH release which means no ovulation.
 +
**Limitations
 +
***Does not protect against STDs
 +
***No longer effective once menses begin again
 +
***Hard to maintain because of social aspects of breast feeding
 +
*NFP / Rhythm birth control
 +
**Requires that couples be highly motivated to maintain compliance.
 +
**'''Failure rate is 1-45%'''.
 +
**NFP can be monitored by several methods: calendar, basal body temperature (BBT), cervical mucus method (Billings), or symptothermal (BBT + Billings)

 +
*Withdrawal method birth control
 +
**One of the oldest methods.
 +
**Failure rate is 20-25%
 +
==Emergency Contraception==
 +
*"Morning after" pill
 +
**Debates over whether it is a contraceptive or an abortifacent
 +
*IUD
 +
**Abortifacent
 +
===Morning After Pill===
 +
*There are two medicinal methods for emergency birth control:
 +
**The Yuzpe method is 2 tablets of 0.25 mg loveonogestrol at 0 and 12 hours.
 +
**The Plan B method is 1 tablet of 0.75 mg levonorgestrel at 0 and 12 hours.
 +
***Plan B has less n / v
 +
***'''Plan B is more effective'''
 +
==Male alternatives==
 +
*Traditional methods
 +
**Periodic Abstinence
 +
***High contraceptive efficacy if rules followed perfectly
 +
***Typical 1st year '''failure rate: 20%'''
 +
***Limited Acceptability: low reliability, inflexibility
 +
**Non-Vaginal Ejaculation
 +
***Historically the major pre-industrial method of family planning
 +
***Limited Reliability: requires skill and self-control
 +
***Typical 1st year '''failure rate: 20%'''
 +
**Vasectomy
 +
***Relative Contraindications: bleeding disorders, allergy to anesthestics, scrotal pathology
 +
***Excises a segment of vas deferens
 +
***'''Failure Rate: 0.1%''' - wait as long as three months
 +
*Condom
-
Spermacide1
 
-
Condoms
+
*Modern methods
 +
**Vas Occlusion
 +
***"reversible vasectomy"
 +
***Lower efficacy than true vasectomy
 +
**Heating
 +
***Principle: brief elevations of testicular temperature suppresses spermatogenesis
 +
***Concept: tight scrotal support – remains to be clinically proven
 +
**Immunocontraception
 +
***Sperm Vaccination – men and women
 +
**Chemical (non-hormonal)
 +
***Target the rapidly proliferating germinal epithelium with drugs, heat, ionising radiation, thereby disrupting mitosis and/or meiosis
 +
 
 +
 
 +
*Hormonal
 +
**WHO Studies utilized weekly testosterone enanthate injections
 +
***Provides both gonadotropin suppression and androgen replacement
 +
***Contraceptive '''Failure Rate of about 8%'''
 +
***Adverse Affects: cardiovascular & prostatic diseases, mood changes
 +
**Other Studies looked at Androgen Combination regimens:
 +
***Non-androgens (estrogen, progestins) to suppress gonadotropins with testosterone
 +
***GnRH Blockades with testosterone add-back
 +
***FSH Blockades

Contraception

Objectives

  • Review basic statistics concerning population growth and pregnancy rates
  • Review basic contraceptive options
  • Review sterilization options

World population growth

  • Population growth is logarithmic since around 1950.
  • The world is growing at about 1.8% each year.
  • Every minute, a woman dies of pregnancy / childbirth complications.
    • 99% of these deaths occur in developing countries.
    • 1 million children left motherless.
  • Maternal mortality rates vary from 1/7 (Niger) to 1/17.4k (Sweden).


  • Birth control is controversial for three reasons:
    • Personal issues
    • Religious issues
    • Political issues

Counseling

  • Counseling about contraception is important.
  • 10% of women don't use birth control.
  • 53% of unintended pregnancies result from these 10% of women (who aren't using birth control).
  • Abortions are highest in those less than 15yo.
    • Abortions decrease as the woman ages to 30-34.
    • Abortions increase again from 35 and up.


  • In 2002 there were 6.4 million pregnancies.
    • 51% were intended
    • 49% were unintended
      • 22% were unintended births
      • 20% were elective abortions
      • 7% were fetal losses


  • Of unintended pregnancies that proceed to live births,
    • 1/4 are "unwanted"
    • 3/4 are "mistimed"


  • Of unintended pregnancies that proceed to live births, about 40% of women were using contraceptives at the time of conception.


Abortion rates

  • The United States of America aborts 22.9 of each 1000 fetuses.
  • Australia: 22.2 / 1000

Birth Controls

  • There are two categories of birth control: contraception (prevent conception) and implant preventors.
  • Contraceptions include:
    • OCPs
    • Norplant
    • Depo-Provera
    • Condoms
    • Diaphragm
    • Foam
    • Rhythm
    • IUDs
  • Implant preventors include IUDs and morning after pills.


  • The most commonly used birth control is tubal ligation making up nearly 50% of contraception use in "non-developed" countries.

Barrier methods

  • Barrier methods include: spermacides, condoms, diaphragms / cervical caps, and sponges


  • Spermacides
    • The active ingredient of spermacides is nonoxynol 9 or actoxynol-3.
      • Nonoxynol and actoxynol disrupt the spermatic cell membrane.
    • The failure rate of spermacides is 15-35%.
    • Patient compliance is generally high.


  • Condoms
    • Male condom failure rate is 5-8% (slippage / breakage) or 5-15%
    • Female condom failure rate is 3% (slippage / breakage) or 5-15%
    • Mechanism of action is to physically block sperm.


  • Diaphragms
    • Mechanism of action is to physically block sperm from gaining access to upper reproductive tract (uterus and fallopian tube.
    • Diaphragms can also hold spermicide.
    • Device must be inserted 1 hour before intercourse.
    • Diaphragm must remain in place for 6-8 hours post-coitus.
    • Failure rate is 10-25%
    • Benefits include:
      • Some protection agains STDs
      • Effective immediately
      • Does not affect breast feeding
      • Does not interfere with intercourse (can be inserted up to 6 hours pre-coitus).
      • No health risks.
      • No systemic side effects.
    • Contraindications include:
      • Hx of toxic shock syndrome
      • Allergy to rubber
      • Allergy to spermicides
      • Repeat UTIs
      • Uterine prolapse
      • Vaginal stenosis
      • Genital anomalies
    • Patient compliance is difficult


  • The sponge
    • Mechanism: contains spermicide
    • Benefits: small, disposible, works for 24 hours (regardless of coitus count)
    • Reintroduced to market in 2009.
    • Failure rate: 26-40%


Hormonal contraceptives

  • Hormonal contraceptives come as oral pills, as injectables, and as an intravaginal ring or a supradermal patch.
  • Injectable contraceptives include:
**Combined injectible contraceptives (CICs)
    • Depo-provera
    • Norplant
    • Implanon

Oral contraceptive pills

  • Failure rate is <1%
  • OCPs can be progesterone only or a combination of estrogen and progesterone (combined oral contraceptives; COCs).


  • Oral contraceptive pills are taken 21 days with 7 days of placebo or no pill.
  • Combined oral contraceptives come in three types depending on their phase:
    • Monophasic: all 21 pills, all of which have some amount of estrogen / progesterone (E/P)
    • Biphasic: 21 active pills, 2 different combinations of E/P
    • Triphasic: 21 active pills, 3 different combinations of E/P


OCP mechanism of action
  • Presence of progesterone decreases FSH and LH levels, including the LH surge.
  • Without the LH surge, ovulation does not occur.
  • Furthermore the endometrial lining is thinner which makes implantation less likely.
  • The cervical lining is thickened which prevents spermatic penetration to the upper reproductive tract.


OCP Benefits
  • Contraceptive benefits of OCP:
    • Highly effective (failure rate <1%)
    • Effective immediately if started by day 7 of menstrual cycle.
    • Pelvic examination not required to initiate use.
    • OCPs do not interfere with intercourse.
    • Few side effects.
    • Convenient and easy.
    • Client can stop use at any time.
    • Can be provided by trained medical staff.


  • Non-contraceptive benefits of OCP:
    • Decrease menstrual flow.
    • Decrease menstrual cramps.
    • Improve anemia (?).
    • Protect against ovarian and endometrial cancer.
    • Decrease bening breast disease and ovarian cysts.
    • Prevent ectopic pregnancy.
    • Protect against some causes of pelvic inflammatory disease.


OCP Effectiveness
  • Perfect use is what is tested but then there is actual or typical use.
    • OCP (combined versions) are 97% effective when taken perfectly.
    • OCP (combined versions) are 92% effective upon actual use.
  • 10 million women are taking OCP; therefore each 1% decrease in effectiveness yields 100k unintended pregnancies
    • 8% decrease simply from perfect use to typical use.


OCP Contraindications
  • Absolute contraindications include:
    • History of vascular disease: pulmonary embolism, deep vein thrombosis, coronary vascular atherosclerosis
    • Systemic disease: lupus, chronic hypertension, liver disease, hypercholesterolemia, migraine headaches with auras.
  • Relative contraindications include:
    • Tobacco use
    • >35 yo
    • Depression
    • Seizures without auras


Injectables

  • Mechanism of action:
    • Suppress ovulation
    • Thicken cervical mucosa
    • Thin endometrium


  • Types of injectable birth controls include:
    • CICs (like OCPs)
    • Depo-Provera
    • Norplant
    • Implantation


  • Failure rate for injectables:
    • CICs: 0.1-1%
    • Depo-Provera: 0.1-0.6%
    • Norplant / Implanton: 0.2-0.6%


  • Injectable limitations
    • Side effects include: nausea, dizziness, breast tenderness, headaches, spotting, light bleeding
    • Effectiveness lowered in combination with other drugs
    • Can delay return to fertility
    • Serious side effects are possible
    • Do not protect against STDs
    • Change the menstrual bleeding pattern
    • User-dependent; that is, the client must return every 30 days.


  • Injectable benefits:
    • Highly effective
    • Effective immediately
    • Pelvic examination not required before use (as with OCPs)
    • Do not interfere with intercourse
    • "Few side effects" (though more than OCPs)
    • Can be provided by trained medical staff
    • No supplies needed by the client

Contraceptive Ring

  • NuvaRing
  • 2 inches in diameter
  • 120mg etonogestrel, 15mg ethinyl estradiol
  • As effective as OCP
  • One ring / cycle
    • 3 weeks in the vagina, 1 week without
  • Not a barrier!

Contraceptive patch

  • Ortho Evra
  • 150 mg norelgestromin, 20mg ethinyl estradiol
  • As effective as OCPs
  • Better compliance (90%) than OCPs (77%)
  • Three patches / cycle, one each week for three weeks; 1 week without patch.

Intra-uterine Devices (IUD)

  • Failure rate of 0.2-3%


  • Mechanism of action can be contraceptive or abortive.
    • Interferes with sperm ability to travel through uterine cavity.
    • Thickens the cervical mucus.
    • Intereferes with reproductive process before ova can reach the uterine cavity.
    • Modifies the endometrial lining to decrease implantation.


  • IUD advantages:
    • Non-hormonal
    • Failure rate of only 0.2-3%
    • Effective immediately
    • Long-term (up to 10 years)
    • Does not interfere with intercourse
    • Immediate return to fertility upon removal
    • Does not affect breast feeding


  • IUD contraindications
    • Pregnancy (risk of ectopic pregnancy)
    • Unexplained vaginal bleeding
    • PID
    • Purulent discharge
    • Distorted uterine cavity
    • Malignment trophoblast disease
    • Pelvic TB
    • Genital tract cancer
    • GU tract infection


Sterilization

  • Sterilization is the most common method of birth control among married couples.
  • Sterilization is the most common method of birth control globally.
  • Only 1% regret sterilization.
  • Failure rate is 1-2% over 10 years


  • 10% of couples choosing sterilization choose vasectomy
    • Failure rate of vasectomy is 0.1%

Miscellaneous

  • Laction is a good birth control, too.
    • Lactation failure rate is 2% for the first 6th months.
    • Mechanism of action is disruption of GnRH release because of frequent, intense suckling at the nipple.
    • Disrupted GnRH means disrupted LH / FSH release which means no ovulation.
    • Limitations
      • Does not protect against STDs
      • No longer effective once menses begin again
      • Hard to maintain because of social aspects of breast feeding


  • NFP / Rhythm birth control
    • Requires that couples be highly motivated to maintain compliance.
    • Failure rate is 1-45%.
    • NFP can be monitored by several methods: calendar, basal body temperature (BBT), cervical mucus method (Billings), or symptothermal (BBT + Billings)


  • Withdrawal method birth control
    • One of the oldest methods.
    • Failure rate is 20-25%

Emergency Contraception

  • "Morning after" pill
    • Debates over whether it is a contraceptive or an abortifacent
  • IUD
    • Abortifacent

Morning After Pill

  • There are two medicinal methods for emergency birth control:
    • The Yuzpe method is 2 tablets of 0.25 mg loveonogestrol at 0 and 12 hours.
    • The Plan B method is 1 tablet of 0.75 mg levonorgestrel at 0 and 12 hours.

      • Plan B is more effective


Male alternatives

  • Traditional methods
    • Periodic Abstinence
      • High contraceptive efficacy if rules followed perfectly
      • Typical 1st year failure rate: 20%
      • Limited Acceptability: low reliability, inflexibility
    • Non-Vaginal Ejaculation
      • Historically the major pre-industrial method of family planning
      • Limited Reliability: requires skill and self-control
      • Typical 1st year failure rate: 20%
    • Vasectomy
      • Relative Contraindications: bleeding disorders, allergy to anesthestics, scrotal pathology
      • Excises a segment of vas deferens
      • Failure Rate: 0.1% - wait as long as three months
  • Condom


  • Modern methods
    • Vas Occlusion
      • "reversible vasectomy"
      • Lower efficacy than true vasectomy
    • Heating
      • Principle: brief elevations of testicular temperature suppresses spermatogenesis
      • Concept: tight scrotal support – remains to be clinically proven
    • Immunocontraception
      • Sperm Vaccination – men and women
    • Chemical (non-hormonal)
      • Target the rapidly proliferating germinal epithelium with drugs, heat, ionising radiation, thereby disrupting mitosis and/or meiosis


  • Hormonal
    • WHO Studies utilized weekly testosterone enanthate injections
      • Provides both gonadotropin suppression and androgen replacement
      • Contraceptive Failure Rate of about 8%
      • Adverse Affects: cardiovascular & prostatic diseases, mood changes
    • Other Studies looked at Androgen Combination regimens:
      • Non-androgens (estrogen, progestins) to suppress gonadotropins with testosterone
      • GnRH Blockades with testosterone add-back
      • FSH Blockades

• Diaphragm & Cervical Caps

• Sponges


chastity

Spermacides • Active Ingredient – Either Nonoxynol 9 or Actoxynol-3

– 15 mins before, up to one hour



• Failure Rate – 15 to 35%



• Patient Compliance – HIGH




36 Spermacide1 vcf2

• Regulate menses – Less flow/anemia, less dysmenorrhea

– Prolonged/continuous dosing




• Less salpingitis/PID w/ +GC/CT

• Less acne and hirsuitism

• Decrease benign breast disease

• Decrease risk of endometrial cancer

• Decrease risk of ovarian cancer

– 1960’s- DES and other estrogens prescribed for human postcoital use

– 1972- “Yuzpe method” • 100 mcg ethinyl estradiol

• 0.5 mg levonorgestrel





Plan B (levonorgestrel 0.75 mg)

EC Methods • Hormonal – Yuzepe – up to 72 hours postcoital • 100 mcg EE + 50 mcg LNG po q 12 hrs x 2



– Levonorgestrel – up to 72 hours postcoital • 0.75 mg q 12 hrs x 2, or 1.5 mg po x 1



– Ulipristal acetate – up to 120 hours postcoital • 30 mg po




• IUD (Copper T) – Place up to 120 hours postcoital
