Hi, Thanks for writing to HCM. I would like to tell you about some facts regarding infertility. The first thing to conceive you need healthy eggs which ovulates normally. And also you should get your husband semen analysis before starting your treatment. If uterus size is less then your uterus is not adequate to hold the pregnancy. For that you need to go for donor womb called as surrogacy . You dont need donor egg if your are ovulating normally. The order of invesigations include male semen analysis female -ovulation study Tube patency Endometrial analysis Treatment depends on what problem is there. For small uterus surrogacy is used. For ovulation defects donor egg is used. Hope I have been helpfull to you. Regards Dr.Deepika Patil
