Infertility

[Solnseeker]

Hello,
Myself and my husband are trying to get conceived for 4 years now.
Latest SA report:
Normal Range
Sperm Concentration: 7M (Should be >=20M)
Total Sperm Count 28M/ejac >=40
Viability 12% >50%(Last test had 68%)
Motile cell count 0.7M/ml >=10 M/ml

Morphologic Criteria for Kruger
Normal heads 0 (Normal: Should be >14%)
Small heads 3
Duplicate 2
Tapered 0
Amorphous 31
Immature 59
Broken necks 0
Tail defects 5

He had been on Clomid for more than a year. It did have a change but was not enough for normal sperm. But is there any other medications that can increase Normal head counts.

Please help me.
