Male Fertility and Semen Quality

Testosterone

The primary anabolic hormone — its natural level depends heavily on sleep, resistance training, body composition and fat mass.

Visceral Fat

Fat tissue that accumulates around the internal organs of the abdominal cavity is metabolically far more active and harmful than subcutaneous fat — even though the two can look similar from the outside.

Andropause

A gradual decline in testosterone in middle-aged and older men, far milder than menopause — a real physiological phenomenon, but one that requires intervention less often than the popular understanding of the term suggests.

Polycystic Ovary Syndrome (PCOS)

The most common hormonal disorder among women of reproductive age — it combines irregular cycles, excess androgens, and insulin resistance, but responds substantially to lifestyle changes.

Clomiphene in Men

Clomiphene citrate — known in Poland under the brand name Clostilbegyt — raises testosterone through a completely different route than TRT: instead of supplying the hormone from outside, it tricks the brain into making the testes produce more of their own. That makes it attractive to men who care about fertility, but the popular claim that it's simply a 'fertility drug' needs to be checked against the actual data.

hCG as Adjunct Therapy in TRT

Human chorionic gonadotropin is sometimes added to testosterone replacement therapy specifically to prevent testicular atrophy and preserve fertility — a problem exogenous testosterone alone doesn't solve.

Tamoxifen in Men

Tamoxifen, the same SERM familiar from oncology, has two real but distinct andrological uses in men — treating and preventing gynecomastia, where the evidence is strong, and potentially supporting fertility, where the evidence is much thinner. We explain where that data actually comes from and why any direct comparison with clomiphene is, for now, only reasoned inference, not a real trial.

PSA and Prostate Health

Prostate-specific antigen is one of the most commonly ordered tests in men over 50 — but also one of the most controversial, due to a high false-positive rate.

TRT and Fertility: Can Testosterone Therapy Cause Infertility?

Testosterone replacement therapy can suppress sperm production even in men with a 'perfect' blood testosterone result — we explain the mechanism, the real scale of the problem, and the concrete options for men who want to have children.

hCG During TRT — When Is It Used, and Does It Help Preserve Fertility?

hCG gets added to testosterone therapy precisely so you don't lose fertility while on treatment — we explain what that looks like in practice: typical dosing, real-world effectiveness, and who it's actually a sensible option for, and who it isn't enough for.

Clomid or TRT — What to Choose for Low Testosterone?

Clomiphene and TRT raise testosterone through completely different routes — one stimulates the body to produce its own hormone, the other replaces it from outside. We explain why that difference matters critically for some men, especially around fertility.

Sauna and Testosterone: Does It Raise or Lower It? The Research Says Both

The internet is split: some claim sauna "cooks" the testicles and lowers testosterone, others say it raises it. The truth is more complex and more interesting than either version: a single sauna session genuinely raises testosterone by about 15%, a hormonal response to heat stress similar to exercise. At the same time, regular, intense sauna use over months can damage sperm count and motility — with no effect on testosterone itself. These are two separate phenomena, governed by different mechanisms, easily confused with each other.
