Document Summary

On day 14 of the menstrual cycle, the woman ovulates. The egg is released from the ovary into the body cavity. It is then picked up by the fimbriae and enters the fallopian tube. It then begins its trip down the tube toward the uterus, reaching it in about five days if it has been fertilized: otherwise, it disintegrates in about 48 hours. It has no means of moving itself (unlike sperm) and is propelled by the cilia lining the fallopian tube. The woman"s cervix secretes mucus that flushes the passageways to prepare for the arrival of the sperm. Sperm are manufactured in the seminiferous tubules of the testes. They were collected and stored in the epididymis. During ejaculation they moved up and over the top of the bladder in the vas deferens then they travelled down through the ejaculatory duct, mixed with seminal fluid and went out through the urethra.
