Hormones in a female play a vital role in sexual and reproductive activity like male. Hypothalamus is situated in the brain which releases a hormone to stimulate pituitary gland. Even though there is regular release of hormones from Hypothalamus, decline and raise in accordance with the emotions, feeling pertaining to their own visual and sensory perceptions. The stimulated pituitary releases two hormones which is similar to the males.
The Follicular stimulating hormone and Luetinising hormones stimulate the ovaries to release a ovum every month and release of “Oestrogen and progesterone” hormones. They regulate feminity, periods and make an individual to conceive.

How hormones regulate a woman's fertility

    A woman's ovaries contain 200,000 to 400,000 egg follicles--small sacs that contain the ingredients needed to form ripened eggs. Over a two-week period in a woman's monthly cycle, FSH causes several follicles in the ovaries to ripen and mature. FSH also orders the ovaries to produce estrogen, which in turn, launches the manufacture of large amounts of LH hormone. LH hormone stimulates the release of an egg from the largest follicle into the fallopian tubes - a process called ovulation.
LH hormone also stimulates the follicle to produce corpus luteum - a collection of yellow tissue that manufactures progesterone. Progesterone and estrogen work together to thicken and prepare the lining of the uterus for a fertilized egg. Together, these hormones swell the lining of the uterus with blood, making it easier for a fertilized egg to implant itself there.

How the egg is fertilized

    An egg is usually fertilized by sperm within the fallopian tubes - but only if the woman has sex with a man around the time the egg is released. The sperm must penetrate the egg to fertilize it.
Sperm can survive for six days after entering a woman's vagina and can fertilize the egg at any time during this period. However, research shows that fertilization is most likely to occur two days before or on the day the egg is released. The fertilized egg then moves on to the uterus, where it implants and grows into an embryo and pregnancy results.

The Unfertilized Egg

    If the egg is not penetrated by sperm, it lives for 12 to 24 hours. The egg and the bloody lining of the uterus then slough off, traveling out of the uterus, the cervix and vagina - a process called the woman's menstrual period.
