Been married for almost a years. Try to get wife pregnant but still no luck.

We always try during peak chance (using apps to track).

Since I read FB pages that sometimes the issue might come from husband itself.

I didnt drink alcohol, not smoke but kinda overweight and age 33 soon. Previously while single kinda my habit to masturbate at least once or twice a week. Sometime could go up to 4 time. Sometime also I break for few weeks. (This been go round since I age 20++).
I think my semen not 'much' compare to what i see in most adult video.
Could this be an issue?

Can anyone also recommend any clinic/fertility centre to try out my "sperm analysis" at KL/Selangor area as well getting advice? Which not too expensive also.
Im very shy guy especially when need to meet doctor for this issue.

At the moment also im consuming proxeed plus about two month and seem like not having positive results yet. Once my part done, I will persuade my wife to check also. She 27 yrs old this year.
