How can the physiological cycle not be measured during the ovulation period?

At present, there are more and more female patients who are unable to get pregnant because they do not ovulate. Therefore, it can be seen that the current incidence of non-ovulation diseases is high, which requires us to pay great attention. The ovulation test strip can determine the ovulation time, but the ovulation test paper is not 100. Divided into hundreds of accurate. In addition, there may be a problem with our own physical condition, which makes it impossible to detect ovulation during ovulation. Next, we will analyze the reasons for the ovulation period from these two points. Ovulation test strips may not be detected for the following reasons: 1. Missing ovulation period and LH peak. 2. Inject or take a progestational drug containing HCG. 3, the operation is not correct or there is a problem with the method of ovulation test paper preservation. Therefore, in order to enhance the accuracy of ovulation test strips, women should pay attention to the following items when using ovulation test strips to test whether ovulation: 1. Ovulation test paper is for one-time use in vitro testing. 2, ovulation test paper can only open the sealed aluminum foil bag before testing, open the original packaging should be used within 1 hour as soon as possible. 3, ovulation test paper should observe the reaction results within the specified time, after 30 minutes the results are invalid. Reasons for non-ovulation: (1) Turner syndrome and simple gonadal dysplasia chromosomal abnormalities, with primary amenorrhea as the main clinical manifestations, elevated gonadotropin and decreased estrogen. Pregnancy can be obtained by in vitro fertilization embryo transfer techniques using eggs donated by others. (2) premature ovarian failure and ovarian confrontation syndrome: high gonadotropin amenorrhea caused by ovarian failure before the age of 40 is called premature ovarian failure, accounting for about 20% to 28% of primary amenorrhea, secondary amenorrhea 4% to 20%. (3) Polycystic ovary syndrome: often manifested as amenorrhea or menstrual thin hair, long-term no ovulation, excessive androgen, estrogen without periodic fluctuations. It is currently a major cause of anovulatory infertility. (4) Unruptured luteinization syndrome: normal menstrual cycle or drug-induced ovulation cycle, ovarian follicles develop into dominant follicles, but the sputum does not disappear or maintain growth 48 h after LH peak in ovulation, and remains in existence for several days. Luteinization occurs and the follicles are not broken.
