This tool does not provide medical advice. The growth of this follicle is stimulated by the hormone FSH follicle-stimulating hormone , which is produced by the pituitary gland in the early phase of the monthly cycle. The process is called spermatogenesis. Far back in the corners of the uterus, on each side, are microscopic canals through which the sperm must squeeze in order to reach the fallopian tube, where it may encounter an unfertilized egg. Thus, nature had to invent some mechanism for allowing a continuous entry to the site of fertilization by a smaller number of sperm. The journey of the egg, or ovum, through the fallopian tube and finally into the uterus after fertilization is extraordinarily hazardous.

It is the most easily observable sign that the egg has gone through enough FSH stimulation to be ready for the genetic events of meiosis, which will ultimately lead to the possibility of fertilization. Once the egg has been allowed to develop in the tube for three or more days, the isthmus suddenly opens up and the early embryo passes quickly into the uterus. Only one or two spermatozoa at a time can pass through this entrance. If they were not lucky enough to pass through the fallopian tube at exactly the moment of ovulation or within twelve hours of ovulation , they would be long gone by the time the egg arrived.
