Female infertility can be caused by a host of different factors; most of them discernable only with the help of a medical professional. Some conditions that are hostile to pregnancy include the following:
Ovulation disorders. Women who do not have regular periods are possibly not ovulating. No ovulation, no pregnancy.
Inflammation of the Fallopian tube. Inflammation of the fallopian tube may lead to blockage. Blocked tubes do not allow the entry of sperm, and therefore interrupts the fertilization process.
Menopause and old age. After a certain age women are less likely to conceive children. When a woman is in her early to mid-thirties, she will be up to 20% less fertile; from her mid to late thirties, she will be up to 50% less fertile. After the age of forty, fertility declines by over 90%. The reason for this is that the quality and quantity of eggs produced by a woman declines with old age. The best time for pregnancy is the early twenties.
Improving the Odds of Pregnancy
Increase your awareness. All women should be aware of their fertile time. Ovulation usually occurs about 14 days before the next period. For women with 28-day cycles, the fourteenth day is generally regarded as the best day for getting pregnant.
Monitor yourself. Changes in a woman?s basal temperature and cervical mucus may signal increased fertility periods. Elevations in a woman?s temperature signals greater chances of pregnancy, as do changes in the appearance and consistency of the cervical mucus. (Its color and density resembles egg whites during periods of great fertility.)
