Low sperm count
Thanks for your query.
The inability to conceive is mainly due to the low sperm count.
There are no promising products or medications which help to have increased sperm count successfully. Anyway you can take ZINC, SELENIUM
and CO-enzyme Q supplements which have shown some response. Protein powders available in market do have these elements in traces and taking them would help.
I would recommend assisted reproductive techniques
like ICSI intracytoplasmic sperm injection
or IUI intrauterine insemination
after sperm concentration technique. These techniques have better result.
