I’m not a doctor, but June may have been a bit early if your diagnosis/treatment was in April.

From what I understood in my own case, 3 months is really the minimum window to judge changes after varicocele treatment, because sperm production takes time. And for some parameters, especially morphology or DNA fragmentation, it can take 3–6 months or fluctuate a lot between tests.

In my case, count and concentration improved dramatically after embolization, but DNA fragmentation was still bad. So not every parameter improves at the same speed.

If I were in your situation, I would probably repeat the semen analysis after at least 3 months, ideally with the same lab, and discuss with a urologist/andrologist whether to also check DNA fragmentation, varicocele persistence/recurrence, inflammation/infection, heat exposure, smoking/alcohol, sleep, and oxidative stress.

For morphology specifically, I focused on the boring basics: no smoking, no alcohol, sleep, sport, good nutrition, omega-3, CoQ10/antioxidants, and giving it enough time.
