I'm under gynea as have pcos n possibly endometriosis. They won't do a laparoscopy as I have other illnesses. But iv been told I ovulate n in the past she said my tubes are clear. So she thinks it's unexplained fertility. My partner has to have his sperm tested n iv been told to get my BMI to 30 n then I can have treatment. Iv got to lose 62lb iv lost 9lb in 2 weeks so 53lb to go, I'm doing meal replacement so hope to lose it quickly. Has anyone else had to lose weight to have treatment?
