Since they definitely trigger excessive contractions of the uterine muscles and of the Fallopian tubes, they may cause displacement of the egg before it has time to be fertilized or to settle in the wall of the womb...
...through the blood to the ovaries, which contain about 300,000 follicles. FSH starts a few of these on a growth process that results in the production of one ovum (egg). Around the 14th day of the cycle, ovulation occurs: the follicle releases the ovum, which travels down the Fallopian tube toward the uterus. If it encounters a live spermatozoon on the way, or soon after its arrival, the ovum will be fertilized...

They are almost but not quite the same chemically as a natural female hormone that controls much of the menstrual cycle and helps to prevent ovulation-release of an egg from the ovary to the Fallopian tube, where a sperm can fertilize...
...work extends back ten years, during which period more than 2,000 living human ova have been studied in vitro. Our prime purpose has been to help women with their Fallopian tubes closed or removed to succeed in having children by obtaining a mature egg, fertilizing it in vitro, and then after four to six days transplanting it into the womb.
