A father's health before conception is equally important
For generations, the burden of fertility has been placed almost entirely on women — their bodies tested, their habits scrutinized, their timelines managed. Yet science has long known that men contribute to nearly half of all infertility cases worldwide, a truth that rarely reaches the center of the conversation. Fertility specialists across India are now calling for a cultural reckoning: that conception is a shared biological undertaking, and that a father's health in the months before pregnancy shapes not only the odds of conception but the health of the child that follows.
- Male factors account for 40–50% of infertility cases globally, yet men are routinely the last to be tested — often only after couples have struggled for months or years.
- Modern lifestyle habits — poor sleep, smoking, obesity, chronic stress, alcohol — silently degrade sperm DNA integrity, raising the risk of miscarriage even when basic sperm counts appear normal.
- When sperm DNA fragmentation exceeds roughly 30%, research shows the risk of recurrent pregnancy loss rises sharply, reframing male health as central to sustaining a pregnancy, not just starting one.
- The biology offers a rare opening: sperm regenerates every 70–90 days, giving men a concrete three-month window to meaningfully improve their reproductive health through diet, exercise, and lifestyle change.
- Fertility specialists argue the deeper barrier is cultural — infertility still carries stigma for men, and testing remains under-normalized, leaving treatable conditions undetected and couples without answers.
When couples begin planning for a baby, the conversation almost always tilts toward the woman — the hormone panels, the supplements, the ovulation tracking. Men tend to fade into the background. But the science tells a different story.
Fertility specialists across India are pointing to research showing that male factors account for 40 to 50 percent of infertility cases globally — rates that hold equally among Indian couples. Yet many men go untested for months or years into a couple's struggle, missing critical windows for early intervention. Dr. Manjunath CS of Birla Fertility & IVF in Bengaluru notes that sperm carries the genetic material shaping embryo development from the very first moment of conception, making its quality far more consequential than commonly understood.
The culprits are familiar: smoking, heavy drinking, obesity, chronic sleep deprivation, unmanaged stress, sedentary habits, environmental toxins. None of these seem obviously connected to fertility, yet all of them suppress sperm production and degrade DNA integrity. Dr. Mandavi Rai of Motherhood Fertility & IVF in Noida explains that a man can have a normal sperm count on paper and still face serious fertility challenges due to underlying DNA fragmentation — a condition increasingly linked to modern lifestyle patterns. Research published in Frontiers in Endocrinology in 2024 found that when sperm DNA fragmentation exceeds around 30 percent, the risk of recurrent pregnancy loss climbs significantly.
The encouraging counterpoint is biological: sperm regenerates every 70 to 90 days. That three-month cycle creates a genuine window for change. Specialists recommend that men begin addressing weight, diet, smoking, alcohol, and nutritional deficiencies — particularly Vitamin D and B12 — at least three months before attempting to conceive. Measurable improvements in sperm quality are possible within that window.
But awareness remains the largest obstacle. Many couples don't know that treatment options exist for severe male factor infertility, from sperm retrieval techniques to microsurgical interventions. Anjali Ajaikumar of Milann Fertility and Birthing Hospitals argues that the shift required is ultimately cultural: fertility can no longer be framed as a woman's responsibility alone. Healthy pregnancies, as Dr. Prakrutha S of Aster CMI Hospital puts it, don't begin with a positive test — they begin months earlier, with two people taking care of their health together.
When couples sit down to talk about having a baby, the conversation almost always tilts in one direction. Women get the hormone tests, the fertility apps, the ovulation trackers, the supplements, the endless advice from aunts and mothers-in-law. Men, meanwhile, tend to fade into the background—called in occasionally to provide a sample, then sent back out to wait.
But the science tells a different story. Male reproductive health shapes conception and pregnancy outcomes just as powerfully as female health does, yet it remains one of the most overlooked pieces of the fertility puzzle. Dr. Manjunath CS, a fertility specialist at Birla Fertility & IVF in Bengaluru, points to research published in the Journal of Human Reproductive Sciences showing that male factors account for 40 to 50 percent of infertility cases globally. The same rates hold true among Indian couples. Yet many men don't get tested until months or years into a couple's struggle to conceive, missing critical windows for early diagnosis and intervention.
The problem runs deeper than simple oversight. Sperm carries genetic material that shapes embryo development from the moment of conception. When sperm quality deteriorates, the damage extends far beyond the initial difficulty of getting pregnant. Dr. Rupnit Kaur, a fertility specialist at Nova IVF Fertility in Zirakpur, explains that male fertility often mirrors overall health. Smoking, heavy drinking, obesity, chronic sleep deprivation, unmanaged stress, sedentary habits, and exposure to environmental toxins all suppress sperm production and degrade sperm quality. These are the hallmarks of contemporary life—long work hours, processed food, five hours of sleep, weekend drinking binges, late-night phone scrolling. None of it seems connected to fertility. Yet all of it affects sperm count, motility, and the integrity of sperm DNA itself.
The consequences can be severe. Dr. Mandavi Rai, a senior consultant in reproductive medicine at Motherhood Fertility & IVF in Noida, describes how low sperm count, poor sperm movement, or damaged sperm DNA can make conception difficult and raise the risk of recurrent miscarriages and implantation failure. Sperm DNA fragmentation—a condition where the genetic material inside sperm becomes damaged—has become increasingly common. A man might have a normal sperm count on paper but still face fertility challenges because of underlying DNA damage linked to stress, smoking, pollution, obesity, infections, or poor lifestyle choices. Research cited by Dr. Manjunath CS, published in Frontiers in Endocrinology in 2024, found that when sperm DNA fragmentation exceeds around 30 percent, the risk of recurrent pregnancy loss climbs significantly. This single finding reframes the entire conversation: male health influences not just the odds of conception but the odds of sustaining a healthy pregnancy.
The encouraging news is that sperm health is not fixed. Sperm regenerates roughly every 70 to 90 days, creating a three-month window for meaningful change. Dr. Prakrutha S, a consultant in fertility and reproductive medicine at Aster CMI Hospital in Bengaluru, recommends that men maintain a healthy weight, eat a balanced diet, exercise regularly, quit smoking, limit alcohol, and correct deficiencies in Vitamin D and Vitamin B12. Dr. Mandavi Rai emphasizes that just as women are advised to prepare their bodies before pregnancy, men should focus on their health at least three months before attempting to conceive. Within that window, addressing weight, smoking, and alcohol consumption can produce measurable improvements in sperm quality.
Yet awareness remains the largest barrier. Many men and couples are unaware that treatment options exist for low sperm count and severe male factor infertility—sperm retrieval techniques, microsurgical interventions, and other advances that can open pathways to parenthood. Anjali Ajaikumar, director of Milann Fertility and Birthing Hospitals, argues that the real shift required is cultural, not medical. Fertility can no longer be framed as a woman's responsibility alone. It is a shared undertaking. Conversations about infertility among men must shed their stigma. Testing and seeking support must become normalized. As Dr. Prakrutha puts it plainly: a father's health before conception is as important as a mother's. Healthy pregnancies do not begin with a positive test. They begin months earlier, with two people taking care of their health together.

Male reproductive health plays a much larger role in conception and pregnancy outcomes than is often recognised— Dr. Manjunath CS, Fertility Specialist, Birla Fertility & IVF

The Hearth Conversation Another angle on the story
Why has male fertility been so invisible in these conversations for so long?
Because pregnancy happens in a woman's body, the focus naturally landed there. But biology doesn't work that way. A man's sperm carries half the genetic blueprint. His lifestyle choices shape that sperm. It's not invisible—it's been overlooked.
So if a man smokes or drinks heavily, that actually damages the sperm itself?
Yes. Smoking, alcohol, stress, poor sleep—they all suppress sperm production and damage the DNA inside the sperm. A man might feel fine, but his sperm is suffering. And that damage can lead to miscarriage or implantation failure months later.
How much time does a man actually have to fix this before trying to conceive?
About three months. That's how long sperm takes to regenerate. So if a couple decides they want to try for a baby, the man has a real window—not just weeks, but a full quarter-year—to make changes that will meaningfully improve his sperm quality.
What's the most surprising thing about sperm DNA fragmentation?
That a man can have a completely normal sperm count on a standard test and still have damaged DNA that causes miscarriages. The old tests miss it. You need to look deeper.
Why do you think men delay getting tested?
Partly shame. Partly because no one tells them to. Women get asked about their fertility constantly. Men are rarely asked at all. It's not on their radar until something goes wrong.
If a couple is struggling, what should happen first?
Both partners should get tested at the same time. Not one, then the other. Not the woman first. Both. Because half the problem might be sitting in the waiting room.
