A simple, nontoxic, effective male oral contraceptive is disclosed which directly effects the metabolism of the sperm by causing an acidotic state in the fluid medium surrounding the sperm thereby inhibiting the sperm's activity. A male oral contraceptive is not medically available to the public, although several forms are in various stages of research and development.
Researchers around the world are working toward male contraceptives that are potentially safer, more effective and more convenient than any contraceptives on the market today. New leads are being discovered all the time - Adjudin and the 'dry orgasm' pill are two recent finds. Times have changed: despite persistent myths, sociological surveys show that men are ready for new contraceptive options. Reliable, reversible male contraception would allow both men and women to participate fully in family planning. Some policymakers and pharmaceutical companies are skeptical about the public's interest in new male contraceptive products, and much of the research is under funded. The aggregated results of the survey are used to show policymakers that there is demand for new male contraceptives.
A vasectomy is considered a permanent method of birth control. A vasectomy prevents the release of sperm when a man ejaculates. It is chosen by men who have completed their families or by men who do not want children. These men want birth control that is intended to be permanent. They prefer vasectomy because most reversible methods are less reliable, sometimes inconvenient, and may have unpleasant side effects for the women in their lives.
During a vasectomy, the vas deferens from each testicle is clamped, cut, or otherwise sealed. This prevents sperm from mixing with the semen that is ejaculated from the penis. An egg cannot be fertilized when there are no sperm in the semen. The testicles continue to produce sperm, but the sperm are reabsorbed by the body.
During a vasectomy:
Your testicles and scrotum are cleaned with an antiseptic and possibly shaved.
You may be given an oral or intravenous (IV) medicine to reduce anxiety and make you sleepy. If you do take this medicine, you may not remember much about the procedure.
Each vas deferens is located by touch.
A local anesthetic is injected into the area.
Your doctor makes one or two small openings in your scrotum. Through an opening, the two vas deferens tubes are cut. The two ends of the vas deferens are tied, stitched, or sealed.
Electrocautery may be used to seal the ends with heat. Scar tissue from the surgery helps block the tubes.
The vas deferens is then replaced inside the scrotum and the skin is closed with stitches that dissolve and do not have to be removed.
The procedure takes about 20 to 30 minutes and can be done in an office or clinic. It may be done by a family medicine doctor, a urologist, or a general surgeon. Vasectomy is not immediately effective. Sperm remains in the system beyond the blocked tubes. You must use other birth control until the sperm are used up. It usually takes about three months.
