Hallow Dear, Polycystic ovaries are formed because the eggs in the ovaries are not getting released from the follicles and are getting stuck up. Unless an egg is released from the follicle, it cannot be made available to the sperms for fertilization, which is the basic requirement and the step for pregnancy. For effecting ovulation from the follicles, first line therapy is by Clomiphene citrate. It is advised that this therapy should not be given for more than 6 months. If this medicine fails to cause successful pregnancy, then gonadotropins may be used for induction of ovulation. Sometimes, these medicines cause ovulation, however are not successful in causing pregnancy. Particularly it is noted so with Clomiphene citrate due to its anti-oestrogenic effect. In addition, in PCOS, there is high insulin and high androgen in the body. Myo-inocitol has proved to be very effective in such situations. Yasmin is a birth control pill which may be successful in regularising your irregular menses due to PCOS; however, it may not be successful in giving you a pregnancy. Moreover, you seem to have Thyroid problem which also affects the fertility. However, you are on Eltroxin and should correct the Thyroid imbalance. I hope this will help you in planning your Management of PCOS. Dr. Nishikant Shrotri
