I’ve been cruising at about 250mg of test a week now for honestly probably a little over a year. My girl and I just started talking about kids. Would cruising at that dosage for that long or possibly longer toast my natural sperm production?
Sperm count is probably low, androgens inhibit spermatogenesis through negative feedback loop (suppression of HPTA). Hell, even guys on 100mg can become azoospermic (dosages higher than natural production of testosterone will induce a dramatic drop in sperm count). That being said, it appears to be an unreliable inducer of azoospermia, as many guys on heavy cycles have gotten their SO’s pregnant.
Pharmaceutical intervention, (injectable FSH would probably be the most effective) will likely allow you to retain fertility on AAS
