The missionary position.
Sometimes what is needed is a change in sexual technique. The man-on-top missionary position places the penis in a boomerang position that causes the ejaculate to shoot farther into the cervix, making it easier for the sperm to reach the egg.
Afterplay, not foreplay.
Foreplay causes the front wall of the uterus to "crawl inside" the abdomen, giving the sperm a longer path to travel to reach the egg. When having sexual intercourse to conceive a child, afterplay is preferable to foreplay.
Simply eating less.
Women who have polycystic ovarian disease (PCOS), a hormonal imbalance which may or may not actually cost ovarian cysts, sometimes are able to conceive after just losing 2 to 5 pounds. The process of losing weight by calorie restriction, not by exercise, lowers blood sugar levels. The ovaries don't receive as much sugar from the bloodstream, they don't make as much testosterone, and about 50 per cent of women who have PCOS resume having normal periods and are able to conceive.
Herbal medicine, but the right herbs for the right partner at the right time.
Herbal remedies really can affect fertility, but it's essential to use the right herb at the right time. Dong quai, for instance, sequesters estrogen. In some women, excess estrogen makes the lining of the uterus too "rough" to receive the fertilized egg. Lowering estrogen levels makes the uterus more hospitable for the implantation of the fertilized egg--but it's not desirable to keep lowering estrogen levels once pregnancy has been accomplished. That's why women taking dong quai and formulas featuring dong quai only use them during the first half of their menstrual cycles. Vitex, also known as chasteberry, can help women with PCOS conceive by lowering testosterone levels. Actually, some men can benefit from lower testosterone levels, too, but most don't. Men should almost never take vitex. On the other hand, passionflower extracts can help preserve testosterone in men who tend to testosterone-deficient, increasing both sexual potency and sperm counts.
