DHEA and Coenzyme Q10 can help in pregnancy, as DHEA has a bi-directional effect in regulating female hormone secretion, which can balance the secretion of androgen and estrogen, improve female ovarian function and egg quality, which can help in pregnancy. The eggs are rich in mitochondria, and if they are deficient, the quality of the eggs will be affected. Coenzyme Q10 can be taken under medical supervision to prevent oxidative damage to the mitochondria and prevent the ovarian function from being reduced, increase the number of eggs and improve the quality of eggs. Taking DHEA and Coenzyme Q10 during pregnancy can improve the chances of conception and promote fetal development, but these drugs need to be taken under the guidance of a doctor.
