Is the chance of a normal pregnancy high with a healthy uterus?

When the uterus and ovaries are normal, ovulation occurs, menstrual cycles are regular, and the fallopian tubes are unobstructed, the chance of pregnancy can reach approximately 95%. Regular sexual intercourse can lead to pregnancy, and having intercourse during the ovulation period further increases the likelihood of conception. Details are as follows.

The primary requirement for pregnancy is the union of egg and sperm. If a woman does not ovulate normally, she typically cannot meet the conditions necessary for conception. Moreover, having intercourse multiple times during the ovulation period increases the chances of pregnancy. The second essential factor is patent (open) fallopian tubes, which are crucial for conception. If the fallopian tube lumen is narrow or blocked, sperm and egg cannot meet and form a fertilized egg within the tube, which usually reduces the likelihood of pregnancy. The third factor is regular menstrual cycles. Under the regulation of the hypothalamus, pituitary gland, and ovaries, each woman normally has a consistent menstrual cycle. Irregular cycles often lead to abnormal ovulation, so regular menstrual cycles are also one of the necessary conditions for pregnancy.

In addition, timing intercourse around the ovulation period is important. During ovulation, sexual activity should be properly scheduled—for example, over an eight-day ovulation period, having intercourse every other day two to three times can significantly increase the probability of pregnancy.
