Hi people Here Some interesting facts about fertility: 1. Ovulation usually occurs on Day 14 of the cycle. Probably the most widely held fertility myth is the notion that women always ovulate on Day 14 of their cycle. If this were indeed true, there would be virtually no need for birth control, since couples could simply avoid that one day. And scores of couples desiring a child would simply have intercourse on Day 14, and Bingo, get pregnant. There are several serious consequences to the Day 14 fallacy: • Many unplanned pregnancies occur because couples think they are safe for unprotected intercourse on any day but Day 14. • Many couples who desire to get pregnant actually impede pregnancy by timing intercourse on Day 14, when, in reality, the woman may ovulate either much earlier or later than that one particular day. • Many diagnostic tests and therapies are performed at an inappropriate time in the woman’s cycle. These include infertility procedures such as post-coital tests and endometrial biopsies, as well as general health procedures such as mammograms and diaphragm fittings. • If a woman does get pregnant, the doctor’s office will usually utilize a "pregnancy wheel" to determine her due date. But this device assumes that women ovulate on Day 14, and therefore could be off by several weeks, leading physicians to perform diagnostic tests at inappropriate times (e.g. amniocentesis) or even induce labor before the baby is fully developed. 2. A normal menstrual cycle is 28 days. Actually, a normal menstrual cycle can vary from about 24-36 days. And not only do cycles vary substantially among women, they often vary within each individual woman. One of the most unfortunate results of this myth is the needless anxiety that it causes women desiring to avoid pregnancy, who are led to believe over and over again that they may be pregnant because their periods are "late." The perpetuation of this belief is related, in part, to people's perception of the perfect Pill cycle (boy, that’s a mouthful of p’s!
