It’s not just her body. His habits can affect fertility too.

In many Indian homes, the woman becomes the fertility patient first. She tracks her periods. She gets the ultrasound. She checks thyroid, AMH, prolactin, sugar, PCOS, weight, diet, sleep, stress, and every other possible explanation. Her phone fills with cycle apps and lab PDFs. Her husband may be supportive. He may drive her to the clinic, pay the bill, sit outside the scan room, and still say, with full confidence, “I’m fine.” He may mean it. He feels healthy. He goes to work, has normal sexual function, and has never had a reason to think about sperm as a medical subject. Yet pregnancy needs both egg and sperm. A fertility file that belongs only to the woman is often half a file. The CDC says both men and women can contribute to infertility, and pregnancy needs sperm to fertilise the egg before the embryo travels through the fallopian tube and implants in the uterus. A problem with one or more of these steps can affect conception.

Why men often delay the fertility conversation

Men do not usually grow up being asked about fertility. Women are asked about periods early. They are warned about age, PCOS, hormones, pregnancy, miscarriage, and marriage timing. Men often meet fertility as a topic only after conception does not happen. By then, the subject feels personal. A semen test can feel like a public exam, even when it is private. A man may worry the report will change how his wife sees him. He may fear family blame. He may think a semen issue means he is less masculine. None of that is medically true, but shame rarely waits for facts. There is also a simple misunderstanding: many men confuse sexual function with fertility. Normal erections and ejaculation do not guarantee normal sperm count, movement, or shape. The report may be normal. It may be mildly abnormal. It may show something that needs a closer look. Either way, the couple gains information they did not have before.

What male fertility really depends on

Male fertility is not judged by height, strength, body hair, sexual desire, or whether a man “looks healthy.” Doctors usually begin with semen analysis, medical history, and sometimes a physical examination. The CDC says male infertility can be caused by problems with testicular or ejaculatory function, hormonal disorders, and genetic disorders. Semen analysis assesses sperm concentration, motility, and morphology, and a slightly abnormal result does not automatically mean a man is infertile.  In plain English, semen analysis looks at how many sperm are present, how well they move, and how they are shaped. These details help doctors decide whether timed intercourse, IUI, IVF, ICSI, lifestyle changes, urology review, or repeat testing may be relevant. One report does not tell the entire story. Fever, illness, medicines, collection errors, heat exposure, smoking, alcohol, and other habits can affect semen results. That is why doctors may repeat the test before making big decisions.

Habits that can affect sperm

Some male fertility factors are outside a person’s control. Others are worth changing because they may affect sperm production or sperm quality. The CDC lists unhealthy habits such as heavy alcohol use, smoking, anabolic steroid use, and illicit drug use as factors that may decrease sperm production. It also lists obesity, smoking, alcohol or drug use, exposure to testosterone, certain medicines, environmental toxins, and frequent heat exposure to the testes among factors linked with declining male fertility.  That does not mean every man who smokes has infertility. It does not mean one drink ruined sperm. Medicine rarely works in those cartoonish extremes. It means these factors belong in the conversation. A man who smokes heavily and has poor motility needs a different discussion from a man who does not smoke and has a normal report. A man using gym steroids or testosterone injections while trying for a baby needs careful medical advice. Testosterone can reduce or shut down sperm production in some men because it interferes with the body’s own hormone signals. Heat matters too. Frequent sauna use, hot baths, tight heat-trapping routines, or laptop heat directly over the lap may be worth discussing if semen results are abnormal. The testes sit outside the body for a reason. They are temperature-sensitive little factories, not decorative equipment.

The wife should not carry the whole file

There is something quietly unfair about a woman doing test after test while the semen analysis keeps being postponed. If she has PCOS, the husband may assume the answer has already been found. If her AMH is low, he may think his report is unnecessary. If she has regular periods, both may keep trying without checking sperm at all. ASRM’s ReproductiveFacts says a third of infertility cases are due to a problem with a partner’s sperm, and another third involve factors in both partners. It also says sperm quality is measured by amount, movement, and shape.  That means a semen analysis is not an optional last chapter. For many couples, it belongs near the beginning. This becomes even more important when the woman is 35 or older, when time matters more, or when treatment such as IUI is being considered. IUI usually needs sperm parameters close enough to normal and at least one open, functioning tube. Choosing treatment without checking sperm is like planning a route without checking whether the bridge exists.

What couples can do now

Start with the least dramatic step: get the semen analysis done properly. Ask the clinic how many days of abstinence are required before the sample. Follow collection instructions. If the report is abnormal, do not read only the red marks and disappear into Google. Ask whether it should be repeated and when. The husband should review his own history honestly. Has he had testicular injury, childhood undescended testes, hernia surgery, mumps after puberty, chemotherapy, radiation, diabetes, genital infection, varicocele, erectile issues, or ejaculation problems? Does he smoke? Drink heavily? Use marijuana or other drugs? Take testosterone or gym steroids? This is medical history, not courtroom evidence. If habits need changing, make them specific. Stop smoking. Cut down alcohol. Avoid recreational drugs. Stop testosterone or anabolic steroids only under medical guidance if prescribed, and tell the fertility doctor. Improve sleep and weight. Check diabetes control. Avoid frequent heat exposure to the testes where practical. Give sperm time. Sperm production takes weeks, so changes may not show overnight.

When to see a specialist

ASRM says couples should seek help after 12 months of regular unprotected sex if the person with ovaries is under 35, and after 6 months if the person with ovaries is 35 or older. It also advises earlier consultation when there is risk for infertility, including childhood testicular problems or difficulty with sexual function.  The CDC also says couples should not delay seeing a provider if the male partner has a history of testicular trauma, prior hernia surgery, prior chemotherapy, infertility with another partner, or sexual dysfunction. Initial evaluation may include semen analysis, tubal evaluation, and ovarian reserve testing depending on the couple’s situation.  A man does not need to wait until a report is terrible before asking for help. Repeated mild abnormalities can matter too, especially when combined with the woman’s age or other fertility factors.  

A Zeeva Consultation

At Zeeva Fertility, a male fertility lifestyle and semen report review can help couples see whether sperm health is part of the delay. The point of the review is not to embarrass the husband. It is to put his health into the same fertility picture as ovulation, age, tubes, uterus, and the couple’s timeline. Sometimes the next step is lifestyle change and repeat testing. Sometimes it is IUI, IVF, ICSI, or a urology opinion. Sometimes the semen report is reassuring and the focus shifts elsewhere. The couple should not have to guess which one applies.

FAQs

Can smoking affect sperm? Yes. The CDC lists smoking among factors linked with declining male fertility and unhealthy habits that may decrease sperm production.  Can alcohol affect male fertility? Heavy alcohol use may decrease sperm production. Occasional drinking should be discussed honestly with the doctor, especially if the semen report is abnormal.  Does normal sexual function mean sperm is normal? No. A man can have normal erections and ejaculation and still have issues with sperm count, motility, or morphology. Can sperm quality improve? Sometimes, depending on the cause. Lifestyle changes, stopping harmful substances, treating medical conditions, and correcting specific problems may help selected men. Should the husband test even if the wife has PCOS? Yes. PCOS may affect ovulation, but male factor can still be present. Testing both partners avoids a half-built plan. When should semen analysis be repeated? If the first report is abnormal, a doctor may advise repeat testing. Timing depends on the result, recent illness, medicines, collection issues, and clinical history.
