Nowadays, there are many families who are expecting a child, but they often fail to do so. There are some problems with women, but these women are often very aggrieved, because they are obviously ovulating, why are they still infertile? First, is your method of calculating ovulation correct and accurate, and is there ovulation or not? The correct methods are the basal body temperature method and the ovulation leukocyte symptoms. The first one, before ovulation is the follicular phase, the ovaries secrete estrogen, and the basal body temperature mostly fluctuates below 36.6°C. After ovulation, the basal body temperature rises by 0.3 to 0.5℃ and continues to fall until 1-2 days before the menstrual period. In this way, the change of basal body temperature in an ovulatory menstrual cycle shows a biphasic curve. It is assumed that the date of the lowest temperature is probably the closest to the date of ovulation, and that ovulation must have occurred on the fourth day of the high temperature and the egg has died. However, if you have an irregular life, the use of basal body temperature to measure ovulation to achieve safe contraception is not very reliable. The second type is when a woman feels a moist and slippery pubic area, with egg-white-like streaks of mucus when wiped with hand towels. When a woman experiences such ovulation symptoms, it is the most fertile time for women and usually lasts for 2 to 3 days. If you are confirmed to be ovulating, but still cannot get pregnant, then you need to start checking for unhealthy eggs. A woman’s eggs are unhealthy, or not mature enough, which can also cause sperm and eggs to not combine properly, thus causing a woman to ovulate but not get pregnant. Secondly, there are problems with the fallopian tubes. If a woman’s fallopian tubes are blocked, have fluid, have adhesions or are deformed, with abnormal peristalsis, these can affect the normal combination of male sperm and female eggs, hindering the normal operation of sperm and affecting normal conception, thus causing women to ovulate and not get pregnant. Finally, whether the reproductive organs are malformed. If a woman suffers from congenital vaginal malformation, vaginal over-stenosis and other congenital developmental abnormalities of the reproductive organs or acquired reproductive organ lesions, these can cause the normal function of the reproductive tract to be affected, causing the reproductive tract to be blocked and not open, resulting in the male sperm not being able to swim normally and not being able to combine with the egg normally, thus causing the woman to have ovulation and not get pregnant. In addition, there are men with abnormal sperm. If the woman’s eggs are healthy, but the man’s sperm is not vigorous enough, or dead sperm, no sperm, etc., this will also cause the sperm and eggs can not be combined properly, thus causing the woman to ovulate but not pregnant. So there are many causes of infertility that can not be generalized, women can go with your husband to check, it is not something embarrassing, avoiding the disease and listening to the secret recipe is the most inappropriate way.
