Penn Fertility Care specialists induce ovulation through the use of fertility drugs to replicate a naturally–produced hormone called follicle stimulating hormone (FSH) also known as a pituitary gonadotropin. FSH stimulates the development of the ovarian follicles located in the ovaries. Each follicle contains an egg. When a woman ovulates, an egg is released.
The medications produce multiple eggs in one cycle and also control the time the eggs, or ovulate, are released so sexual intercourse, intrauterine insemination (IUI), and in vitro fertilization procedures can be scheduled at the most likely time to achieve pregnancy.
For women with regular 28–day cycles, ovulation usually occurs on days 13 to 15. For women with irregular cycles — between 27 to 34 days — ovulation is usually difficult to predict. Therefore, the use of an at–home ovulation detection test should begin on day 10 and continue until ovulation is indicated or through day 20.
If a woman is not having an IVF procedure, then, once ovulation is detected, a woman can either have intercourse with her partner or, if recommended, do an intrauterine insemination. The goal of IUI in place of intercourse is to increase the number of sperm that reach the fallopian tubes and, presumably, increase a woman's chance of becoming pregnant.
