As per your sonographic report, it appears that your follicle did not rupture in this cycle and a cyst
may have developed as indicated by the size. As such, your chances of conception are almost nil in this cycle. Follicles usually rupture when they are about 18 mm. With a normal semen analysis
, sperms may be available for fertilization as long as 5 days after an intercourse, while an ovum cannot live longer then 24 hours in the natural state. Hope this information is useful to you. Wish you good health.
