Question: After four months of pregnancy, the ovary can be removed and the pregnancy remains still gets sustained to the end of gestation period, How does this happen, please let me know.

Yes, a pregnancy can continue after the removal of both ovaries at 4 months, or the second trimester, because the placenta takes over hormone production from the ovaries to maintain the pregnancy, though the patient will need progesterone supplementation and will experience immediate surgical menopause. The ovaries are primarily needed to establish the pregnancy in the first trimester, and by the second trimester, the placenta is sufficiently developed to produce the necessary hormones, including estrogen and progesterone, for the remainder of the pregnancy and childbirth.
