Talk to Gynecologist on Infertility

Iam trying to conceive a child fir the last 5 years. I have done ICSI this month and its failled. I have luteal phase defect and my husband has teratozospermia however his all other parameters are whithin normal range. My doctor advised me for ICSI unfortunately its unsuccessful. According to Doctor, reason behind ICSI failure is immunological issues. He advised me steroids , intra lipids and anti coagulant before starting 2nd round of ICSI. Furthermore he suggested to do some investigations which i did already before starting my ICSI. I have a question from DR rukhsana what ahe will suggest me further about my problem. Any other suggestions if i get from her expertise i would be really greatful. Iam trying for 5 years to have a child. My cycles are regular of 23 days.
