What is the probability of pregnancy during ovulation?

If a woman's menstrual cycle is relatively regular, and there are no factors that cause infertility in both men and women, then the probability of pregnancy during ovulation is about eighty or ninety percent. However, if the woman's menstrual cycle is irregular, coupled with the existence of infertility factors, then the probability of pregnancy during ovulation will be greatly reduced in this case, probably only about 10%. This depends on the specific factors that cause pregnancy difficulties, such as female fallopian tube obstruction, patency, or gynecological inflammation, as well as male sperm quality abnormalities, which will affect pregnancy.
