Fertility control measures
Methods/devises designed to make a fertile act infertile.
An agent that prevents conception (fertilization).
An agent that impedes implantation. (abortifacient)
An agent that disrupts pregnancy after implantation. (abortifacient)
Methods of fertility control
Barrier, surgical, and hormonal.
Prevents sperm from entering uterus, ex condoms.
Cutting and sealing off of ducts that transport gametes that prevents fertilization, ex vasectomy and tubal ligation.
Cutting and tying the vas deferens, makes a man sterile because sperm die in duct and are consumed by immune cells. Can be reversed but very difficult and doesn't always work.
Sealing uterine tubes, makes a woman sterile.
Fertility hormones are used to promote infertility, mimics hormones of pregnancy so that ovulation does not occur. ex the 'pill'. Generally contains progestin and estrogens. 3 methods of action: 1. Block hormonal signals for ovulation, 2. creates hormonal signals that thicken cervical mucus, and 3. prevent full growth of endometrial lining, impedes implantation that could promote miscarriage. Hormonal methods also effects breastfeeding by negatively altering nutritional composition and amount of milk produced, and may inhibit endometrial gland formation possibly rendering a female child infertile. Endometrial effect: long-term usage may cause permanent thinning and impair fertility. Normal cycles after cessation may return immediately or may require multiple months for cycle to return to normal. Risks to developing child - increases risks of miscarriages, ectopic pregnancies, and can cause developmental defects if taken during pregnancy. The pregnancy may not be recognized.
A group of hormones with a similar chemical structure.
Progestin - a synthetic progestogen.
Progesterone - a natural progestogen.
A synthetic progestogen.
Aids prevention approches
Condom distribution - Theory: Usage prevents exposure to body fluids during sexual intercourse thus the rates go down. Results: Appears ineffective. Rates do not decline and may even increase. Risk compensation - increase in promiscuity because of the 'lower risk'.
ABC approach - A. Abstinence, B. Be faithful, C. Condoms as a last resort. Reduced HIV rate dramatically in Uganda.
The increase of risky behavior to a greater extent than the decrease in risk from an intervention. Increase in promiscuity > lower risk (from condoms)
Calendar methods, Cervical mucus, Basal body temperature, Hormone monitor.
Day of ovulation + ~ 5 days before.
Times not in fertile phase.
Uses length of typical cycle to estimate fertility. Least accurate method because pre-ovulatory phase inconsistency hinders effectiveness.
Mucus changes over cycle time. Changes produced by estrogen/progesterone levels. Clearness = more fertile. Stretchiness = more fertile. Predicts approaching ovulation and ovulation.
Basal body temperature
Body temperature when at rest. Rise indicates ovulation has occurred caused by progesterone increase.
Detects the estrogen rise and LH surge. Estrogen rise - indicates when ovulation may be occurring in the next few days.
LH surge - indicates that ovulation will occur soon.
Effectiveness if method is used perfectly.
Effectiveness in typical use.
