reproductive system. The Columbia Encyclopedia, Sixth Edition. 2001-05 (703 words) |
 | In the human female reproductive system, ova are produced in the ovaries, two small organs set in the pelvic cavity below and to either side of the navel. |
 | In the male reproductive system sperm are produced in the seminiferous tubules of the testes, two organs contained in the scrotum, an external sac in the groin. |
 | Disorders that may affect the proper functioning of the reproductive system include abnormal hormone secretion, sexually transmitted diseases, and the presence of cancerous tissue in the region. |
| The Reproductive System - Design, Workings, Ailments, Taking care (9604 words) |
 | The main functions of the female reproductive system are to produce ova, receive sperm from the male penis, house and provide nutrients to the developing embryo and fetus, give birth, and produce milk to feed offspring. |
 | The activities of both reproductive systems are controlled by hormones (chemicals produced by the body that affect various bodily processes) released from the pituitary gland, which is located at the base of the brain behind the nose, and from the gonads in each system. |
 | The pills contain hormones that are released into a woman's system on a regular basis to prevent pregnancy, either by inhibiting ovulation, preventing implantation of a fertilized egg, or by thickening the secretions throughout a woman's reproductive system so that her partner's sperm has less of a chance to meet her egg. |
