Neem & Birth Control


    Several studies showed that neem oil appears to be a safe and very effective contraceptive, pre and post coital (before and after sex). <See a compilation of researches here> (until 2005).

    The way it was applied in the studies it almost was 100% effective in preventing pregnancies. During in vitro experiments, neem oil also totally immobilized sperm cells within 20 to 30 seconds of being in contact with neem oil.

    It is nothing new... "In the first century B.C., Charaka, the Indian physician, gave a detailed method for using neem for contraception. Cotton soaked in neem oil was kept in the vagina for fifteen minutes before intercourse. This killed the sperm."

    Newer studies showed that neem oil contraceptive indeed kills sperm in the vagina within 30 seconds and remains active for five hours. It causes no irritation or discomfort like the chemical based spermicidal foams do. (Apart from the awful smell.)

    In addition neem oil acts as a lubricant, and it may also offer some protection from vaginal and sexually transmitted diseases. Neem is well known to be a powerful antimicrobial herb. Neem oil, when applied vaginally, has been shown to be very effective against several sexually transmitted diseases (STD’s). There has been strong evidence found in a number of studies that leads us to believe that neem can be successfully used against gonorrhea, syphilis, Chlamydia, herpes simplex-2 and possibly even HIV-1. Research is underway, and more research is needed to see how neem can be of value in fighting these and other STD’s.


    To prevent pregnancy, use a water based vaginal lubricant with ten-percent neem oil added. Apply before intercourse to give the surface of the vaginal wall time to become coated with the material. If there was no neem lubricant available during intercourse applying the lubricant soon sifter inter-course will prevent implantation.


    Neem leaf tablets ingested for one month produced reversible male antifertility without affecting sperm production or libido (Deshpande, 1980) (Sadre, 1984). In India and the United States, exploratory trials show neem extracts reduced fertility in male monkeys without inhibiting libido or sperm production (Sharma, et al, 1987).

    In a test of neem's birth control effects with members of the Indian Army, daily oral doses of several drops of neem seed oil in gelatin capsules were given to twenty married soldiers. The effect took six weeks to become 100 percent effective, it remained effective during the entire year of the trial and was reversed six weeks after the subjects stopped taking the capsules. During this time the men experienced no adverse side effects and retained their normal capabilities and desires. (Vietmeyer, 1992) There were no pregnancies of any of the wives during the period of the study.

    For long term birth control for men it appears that a very minute amount of neem oil injected in the vas deferens provides up to eight months of birth control. The tests revealed no obstructions, no change in testosterone production and no anti-sperm antibodies. The local lymph nodes showed increased ability to respond to infections indicating an immune response may be responsible for the birth control effect in men as it is in women. (Upadhyay, 1993).

    However, you must take into account about the evidence that some women became pregnant when their husbands were taking neem leaves (capsules or tea). Then, it also shows that this contraceptive male method is not 100% effective. And the best option would be combining it with the use of neem oil as a spermicide.

Precautions: Taking Neem oil internally is not recommended, specially for children. Neem oil can be made safe for consumption, but the normal raw or refined product that you buy for use around the garden, or even for external applications on the skin, is not intended for internal use. Some studies showed that it is totally safe, even in higher doses, but others showed that extended internal use can have side effects.

Important: Since everyone's body is different and reactions to products can vary from extremely positive to extremely negative, use of any product or even food should be curtailed immediately if any side effects or changes in bodily function appear. This holds true for neem and any other herb or new food. Test your own tolerance or sensitivity to neem in small incremental steps, first on the skin, then in minute quantities orally. Again, if any sings appear of intolerance for neem, stop its use immediately.- John Conrick.
