Sample text

Women who consume more than 500 mg of caffeine take longer to conceive than women who don’t. And an intake of more than 500 mg of caffeine has also been reported to increase the risk of miscarriage. Fertility experts recommend that women who are trying to conceive limit their caffeine intake to a maximum of 250 mg a day; that is, fewer than about three 8-ounce cups of coffee a day. A cup of black or green tea typically contains less caffeine than coffee. Black tea contains the most caffeine—from 40 to 100 milligrams per cup if you steep it for five minutes—but if you steep it for three minutes it contains about half that amount.

This —Diane, 38 may be due to the various medical conditions such as those mentioned earlier, or to genetic problems in the embryo. Miscarriage is a relatively common occurrence, as you can see from the previous table. Older women are also at increased risk of having stillborn babies, low-birth-weight babies, premature deliveries, and Caesarian sections. As a result, their babies are at increased risk for serious health problems. Babies of older women are also at risk for having genetic or congenital problems.

Sperm, the male reproductive cells, also each have 46 chromosomes to start. They, too, must shed half their chromosomes before meeting up with a mature egg. In this way, the fertilized egg will have a full complement of chromosomes— half from the egg and half from the sperm. LH also helps ripen the follicle further, causing it to rupture and release a mature egg. The ovum, or egg, is expelled from the follicle on the ovary, grabbed by the fimbria at the end of the Fallopian tube, and journeys down the narrow Fallopian tube on the road to possible fertilization.
