Causes of infertility during ovulation

There are many reasons why ovulation is not pregnant; first of all, tubal blockage may lead to infertility; in addition, endometrial problems may also lead to infertility; low male sperm activity may also lead to infertility; if ovulation is normal, fallopian tubes are normal, and endometrium is normal, it may be a male cause of infertility; the odds of pregnancy in the same room during ovulation are more than ten percent, and some people mistakenly think that the same room must be pregnant, which is also wrong. Therefore, if the test results are normal, it is normal for ovulation not to be pregnant after cohabitation.
