Is it possible to get pregnant without LH surge?
Is it possible to ovulate without a LH surge? No, it’s not possible to ovulate without a LH surge. That’s because LH is a hormone released by the pituitary gland and plays a fundamental role in the egg’s growth and maturation; a large burst of LH induces the release of a mature egg.

Does estrogen surge cause LH surge?

When the amount of estrogen reaches its upper threshold, the egg is ready for release. The brain then produces a surge of luteinizing hormone (LH), triggering ovulation. The release of the egg from the follicle and ovary happens about 24 hours later (10–12 hours after LH peaks) (13, 17).
