question: Hello Im 26 & I got one ovary removed last month due to huge (15cm) repetitive mucinous cyst. My cycles have always been regular. The doc did follicular study on my left ovary and i have a monofollicule of 1.92 cms & my ebdo seems good. The doc has advised for fertigyn 5000 iu IM INJECTION. Is this necessary as I have never tried to conceive naturally? Also how does this injection help?
