I am 34 years female. I have been married for 16 years. In these years I had 2 miscarriages one in 1999 and another in 2008. I have finished with all my treatments and the reports are normal. I have also done the treatment for blockage of tubes. And it is also normal. But I do not understand y I am not conceiving. My husbands sperm count is 20 million. Please help.
