On the other, it takes a remarkably long time to train as a physician. Some specialists can take 16 years or longer to complete their training, and even family practitioners -- who treat a wide variety of conditions for patients of all ages -- typically require a total of 11 years of schooling.
The fact of the matter is that, while you will only ovulate for about 24 hours, the period of time that you are actually fertile is more like 5 or 6 days. After sexual intercourse, once the sperm are in a womanâs body, they can survive for as many as five days afterwards.
Time of ovulation. Women often believe that ovulation occurs mid-cycle. It actually occurs 12-16 days before the next period starts. So, although a woman with a 28-day cycle may ovulate mid-cycle (between day 12 and day 16), a woman with a 36-day cycle will ovulate between day 20 and day 24. For women with regular cycles, an easy way to approximate the time of ovulation is to subtract 16 from the number of days in the cycle and then add 4.
