Using Vitamin C to Prevent Conception
(Ascorbic Acid)

Vitamin C also know as Ascorbic acid can be used in a variety of ways to prevent conception. Of course the best prevention is to keep the sperm out of the vagina in the first place. If, for example, a condom breaks, or unprotected intercourse occurs during a woman's fertile time, two tablets may be placed within the vagina next to the cervix as soon as possible. This increases the acid levels in the vagina. The sperm need an alkaline environment to survive; fertile mucus.

 Tablets of Vitamin C could also be placed inside the vagina just before intercourse, giving them just enough time to dissolve. Hopefully making things acidic enough to kill the sperm upon ejaculation. This can be irritating however, and another source only recommends this in emergency situations. 2 500 mg tablets (non-chewable) placed inside the vagina immediately following unprotected sex, or condom rupture, twice a day for 3 days. Soothe afterwards with aloe vera and acidophilus If you are interested in home made spermacides you may want to check out what I have collected about this topic.

If you know fertilizing intercourse took place less than 72 hours ago, you might want to consider Emergency Contraception offered by the medical establishment, as it may be more effective in preventing unwanted pregnancy, find out more for yourself.

Vitamin c can be taken internally as an emergency contraceptive during the time between ovulation and when menstruation is expected. Apparently the ascorbic acid interferes with the production of progesterone. Progesterone is needed to prepare the uterus for pregnancy as well as maintain a pregnancy.

Look for the synthetic form of vitamin c, it should contain no bioflavinoids, and should say in the ingredients ascorbic acid. It is easily obtained from the local grocery store or pharmacy.

Rebecca Chalker in her book, A Woman's Book of Choices lists a dosage of 6 - 10 grams over the course of a 24 hour period for 5 to 10 days, not to exceed 10 days. You will have to determine the correct about for your self; consider body weight, and whether you take vitamin c on a regular basis might need to take 10 gram dose rather than a lower one. You have to decide for yourself, so listen closely to your body.

There can be side effects from taking mega doses of vitamin C. Most of the more serious ones occur from extended use. With 10 day maximum used here, these are unlikely to occur. The short term side effects you may experience are constipation or diarrhea, headaches, upset stomach, abdominal cramps, hot flashes, and/or rashes. However, I have not had anyone tell me they experienced any of these symptoms. The only one I experienced was constipation.

People who take anti-coagulants, who have sickle-cell anemia, or who have difficulty metabolizing vitamin c should not take mega doses of vitamin c with out the supervision of their physician.
