Infertility in Men - Assisted Reproductive Technologies

Lifestyle Changes

Timing and Monitoring Sexual Activity for Best Results

Both male and female hormone levels fluctuate according to the time of day, and they also vary from day to day and month to month. Some timing tips might be helpful.

Fertility and Seasonal Changes. Some studies have reported higher sperm counts in the winter than in the summer. For women, fertility rates as measured by treatment success are highest in months when days are longest.

Monitoring Basal Body Temperature. To determine the most likely time of ovulation and therefore the time of fertility, a woman should take her body temperature, called her basal body temperature. This is the body's temperature as it rises and falls in accord with hormonal fluctuations.

By studying the temperature patterns after a few months, couples can begin to anticipate ovulation and plan their sexual activity accordingly.

Frequency of Intercourse. It is not clear how often a couple should have intercourse in order to conceive. Some doctors think that having sex more than 2 days a week adds no benefits. In addition, frequent sexual activity lowers sperm count per ejaculation. Some studies have indicated, however, that having intercourse every day, or even several times a day, before and during ovulation, improves pregnancy rates. Although sperm count per ejaculation is low, a constantly replenished semen supply is more likely to result in a fertilized egg.

Dietary Considerations

Everyone should eat a healthy diet rich in fresh fruits, vegetables, and whole grains. Replace animal fats with monounsaturated oils, such as olive oil. Certain specific nutrients and vitamins have been studied for their effects on male infertility and sperm health. They include antioxidant vitamins (vitamin C, vitamin E) and the dietary supplements L-carnitine and L-acetylcarnitine. To date, there is no conclusive evidence that they are effective.

Other Lifestyle Changes

Other tips for helping fertility include:

• Avoid cigarettes and any drugs that may affect sperm count or reduce sexual function.
• Overweight men should try to reduce their weight as obesity may be associated with infertility.
• Get sufficient rest, and exercise moderately but regularly. (Excessive exercise can impair fertility.)
• Stress may contribute to reduced sperm quality. It is not known if stress reduction techniques can improve fertility, but they may help couples endure the difficult processes involved in fertility treatments.
• Although studies indicate that tight underwear and pants pose no threat to male fertility, there is no harm in wearing looser clothing.
• To prevent overheating of the testes, men should avoid hot baths, showers, and steam rooms.
• Avoid use of sexual lubricants (Astroglide, KY-jelly) as they may affect sperm motility.
