Hi Devi, I find your result erratic. FSH once raised ( More than 7 mIu/ml, bad if 12miu/ml) cannot just come down like that, you have been mislead. FSH is a hormone produced by a gland, Pituitary , in brain. FSH ( Follicle Stimulating Hormone) stimulates ovaries to produce eggs(which lies within follicles) . If eggs come in first say , FSH will not raise further, but if number of eggs in ovaries is reduced or not responding, especially around menopausal age, FSH will try to stimulate again , I mean higher dose of FSH come. It keeps increasing till eggs are released. So lesser the eggs , more the FSH will be. It will stay so. If your periods are regular with good flow forget about FSH or LH FSH is always to be checked on DAY 3or 4 of periods. Even further confirmatory is Serum AMH in first half of the periods. For IUI to be successful you will need good hormone stimulation from 2nd or 3rd day of cycle, till the day 10-13 of periods when follicles are right size to rupture. As you have not given any other details like your age,other hormone levels, scan findings, husband factors etc. Kindly see if the following checklist of investigations is done Husband- Semen analysis at least 2- done 4 weeks apart preferably in an infertility center ( examination done by andrologist), Blood sugars Wife - Blood Sugars, Thyroid profile Ultrasound scans to evaluate Uterus , Ovaries & adnexa Confirm tubal patency- most important- Tube is the connection between uterus & ovaries( the bridge where sperm meets the egg & forms a baby) this is size of hair follicle & cannot be seen on scans. So check with HSG( Xray with dye), or SSG ( Scan with dye) or Laparoscopy If all this done & found normal , nothing can stop a pregnancy with God s will Hope I have cleared your query All the best Dr.Balakrishnan
