follicles then release the hormone estrogen. As the follicles mature over the next several days more and more estrogen is released. LH causes the most mature follicle to release an egg (ovulation). Some women experience cramping during ovulation. Basal body temperature rises after ovulation. The follicle that released the egg becomes the corpus luteum which releases progesterone and estradiol. LH and FSH decline. Estrogen rebuilds the endometrial tissue and stratum functionalis. Progesterone causes the

connected to the fallopian tube which connects to the ovaries. There are two oval-shaped ovaries, one on each side of the uterus, the produce and store the eggs and when it is time, they release the eggs and that is called ovulation. “The female system enables a woman to produce eggs (ova), have sexual intercourse, protect and nourish the fertilized egg until it is fully developed, and give birth.” (Steven Dowshen, Femal Reproductive System, 2010) This can’t happen without the organ called gonads, and

reproductive system Human reproduction takes place as internal fertilization by sexual intercourse. During this process, the erect penis of the male is inserted into the female's vagina until the male ejaculates semen, which contains sperm, into the female's vagina. The sperm then travels through the vagina and cervix into the uterus or fallopian tubes for fertilization of the ovum. Upon successful fertilization and implantation, gestation of the foetus then occurs within the female's uterus for approximately

MAJOR PARTS OF OB/GYN The female reproductive system is designed to carry out several functions. It produces the female egg cells necessary for reproduction, called the ova or oocytes. The system is designed to transport the ova to the site of fertilization.the fertilization of an egg by a sperm, normally occurs in the fallopian tubes. The next step for the egg is to implant into the walls of the uterus, beginning the initial stages of pregnancy. If fertilization and/or implantation does not take
