Nowadays, there are a lot of families looking forward to the arrival of children, but often fall through. There are some problems with women, however, these women are often also very aggrieved, because they obviously have ovulation ah, why still infertile? This is from several aspects, first of all, you calculate ovulation method is correct and accurate, whether there is ovulation or not? The correct methods are the basal body temperature method and ovulation leukorrhea symptoms. The first one, before ovulation is the follicular phase, the ovary secretes estrogen, and the basal body temperature mostly fluctuates below 36.6℃. After ovulation, the basal body temperature rises 0.3 to 0.5 ℃, and continues until 1 to 2 days before the onset of menstruation begins to decline. In this way, the change of basal body temperature in a menstrual cycle with ovulation shows a biphasic curve. It is hypothesized that the date of the lowest point of body temperature may be the closest to the date of ovulation, and that on the fourth day of the high temperature an egg must have been ovulated and the egg must have died. However, if the life is not regular, then the use of basal body temperature to measure ovulation to achieve safe period contraception is less reliable. The second type, women feel wet and slippery pubic area, when wiped with hand paper there will be egg white-like streaks of mucus. When a woman experiences such symptoms of ovulation, it is the time when she is most likely to conceive and usually lasts for 2 to 3 days. If it is confirmed that you are ovulating, but you still can’t 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 the sperm and egg 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 tube has blockage, fluid accumulation, adhesion or malformation of the fallopian tube and abnormal peristalsis, all these will affect the normal combination of male sperm and female egg, hindering the normal operation of sperm and affecting the normal fertilization, thus causing a woman to have ovulation but not pregnant. Finally, whether the reproductive organs are deformed. If a woman suffers from congenital vaginal deformity, vagina is too narrow and other congenital developmental abnormalities of the reproductive organs or acquired reproductive organ lesions, these will trigger the normal function of the reproductive tract to be affected, resulting in the blockage of the reproductive tract, not smooth, resulting in the sperm of the male can not swim normally, can not be combined with the egg normally, thus resulting in the female has ovulation but not pregnant. In addition, there is also abnormal sperm in men. If the woman’s egg is healthy, but the man’s sperm is not vigorous enough, or dead sperm, no sperm, etc., this will also cause the sperm and egg can not be combined normally, thus causing the woman to have ovulation but not pregnant. So there are many causes of infertility, can not be generalized, women can go with your husband to check, it is not something embarrassing, avoiding treatment, listening to secret prescriptions is the most inappropriate method.
