Pip: When a pregnancy test stays negative, the instinct is to look at the woman first — and apparently last, and everywhere in between, before anyone thinks to check the man. Dr. Kalpesh Kapadia, uroandrologist in Ahmedabad, has a few things to say about that instinct.
Mara: This episode covers male infertility — what causes it, how it is properly diagnosed, what the treatment ladder actually looks like, and where the most meaningful advances in care are happening right now.
Pip: All of it grounded in what the post actually says, not what a supplement company would prefer you to believe.
Mara: Let's start with causes, tests, and treatment options — the full picture of male infertility evaluation.
Male Infertility: What It Is, Why It Gets Missed, and What to Do
Pip: The core tension in this post is a simple one — male infertility is common, frequently treatable, and almost always investigated too late, because the man is tested last.
Mara: The post opens with exactly that observation, and it does not soften it: "Around 15% of couples worldwide do not conceive within a year of trying, and a male factor is involved in roughly half of those cases. In a meaningful number, the man is the only reason conception has not happened."
Pip: Half. That is not a footnote statistic — that is the reason to put the semen analysis on the same checklist as the female workup, from the very first visit.
Mara: And the post is direct about what a semen analysis can and cannot tell you. The WHO 2021 reference limits — things like 16 million sperm per milliliter, 42% total motility, 4% normal morphology — are the fifth percentile of men whose partners conceived within a year. They describe a probability, not a verdict. A count below those numbers does not mean sterility.
Pip: Which matters because men apparently arrive in clinic distressed by a count of 12 million, having read that 16 is "normal," without realizing the reference value is a percentile, not a pass mark.
Mara: The post is equally clear on causes. Varicocele — enlarged veins draining the testis — is described as "the single most common correctable cause of male infertility," found in around 15% of infertile men. Hormonal disorders, genetic conditions, obstructions, infections, and medication effects all feature, but the post flags one cause with particular urgency: exogenous testosterone and anabolic steroids, which switch off the body's own sperm production, sometimes for many months.
Pip: The post's phrasing on testosterone therapy is worth repeating because it is so often gotten wrong in practice.
Mara: It says: "Testosterone must never be given to a man who wants children." If low testosterone is the problem and fertility is the goal, the treatment is hCG, gonadotropins, or a SERM — not testosterone gel or injections.
Pip: The treatment section is structured as a ladder, which is a useful frame — lifestyle changes and stopping offending drugs at the bottom, microsurgery and assisted reproduction higher up, with the right rung depending entirely on what the diagnosis actually shows.
Mara: The advanced options section is where the post gets into microdissection TESE — microTESE — for non-obstructive azoospermia. The technique uses an operating microscope to identify the thicker tubules most likely to contain sperm, retrieving far less tissue than a conventional biopsy. Reported sperm retrieval rates run around 40 to 60 percent depending on the underlying cause.
Pip: So azoospermia — no sperm in the ejaculate at all — is genuinely not the end of the road it was once considered.
Mara: The post is careful to say that microTESE is highly technique-dependent, and belongs with an experienced microsurgical team working alongside an embryology lab. It also covers the prognosis section honestly: where complete AZFa or AZFb deletions are present, or where microdissection finds nothing, the appropriate response is to say so clearly and discuss donor sperm or adoption — not to sell another cycle.
Pip: Honesty about limits as a clinical value. That is a harder thing to deliver than another round of treatment.
Mara: The post closes with a prevention list and a myths-versus-facts table, and one line from the expert insight section pulls the whole piece together: evaluating both partners from the very first visit is, in practical terms, "one of the highest-value decisions a couple can make."
Pip: A semen analysis is inexpensive, non-invasive, and available almost everywhere — which makes testing the man last not just a medical error, but a genuinely avoidable one.
Mara: The throughline across all of this is time — delay is described as the enemy in fertility medicine, and the post makes that case in every section.
Pip: Causes, tests, treatment, prognosis — next time, we will see what else is on the site worth unpacking.
