A man can improve fertility by scheduling a checkup, stopping nicotine and drugs, trimming alcohol, sleeping well, and reviewing meds about 3 months ahead.
Pregnancy prep isn’t only a “her” thing. Sperm quality, timing, and the habits you run on autopilot can affect how long conception takes. The upside is simple: most changes are practical, and you can start today.
This guide lays out what to do first, what to book, what to track, and what to fix at home. It’s written for real life—work schedules, imperfect sleep, and normal stress.
What to do first in the next 7 days
These steps clear the biggest unknowns early and set a start date you can work toward.
- Pick a target month for trying, even if it’s flexible.
- Book a checkup and bring a list of all meds and supplements.
- Stop nicotine (smoking, vaping, pouches).
- Stop recreational drugs, including cannabis.
- Start a simple log: sleep hours, alcohol drinks, workouts, and fevers.
Why the “3-month” runway helps
Sperm take time to develop and mature. A 90-day runway gives your body a chance to produce a new batch under better day-to-day conditions. You don’t have to be perfect. You do want steady habits more days than not.
How Should Men Prepare For Pregnancy? A 90-day plan
Use this as your checklist. It keeps you moving without turning life into a spreadsheet.
Weeks 12–8 before trying
Start with the changes that take time: nicotine out, drugs out, and sleep on a schedule. If you take prescription meds, don’t stop them on your own. Some medications can affect erections, hormones, or sperm, so a quick review with the prescribing clinician can save you from guessing.
Weeks 8–4 before trying
Set your baseline routines. Train two to four days a week, eat regular meals, and keep alcohol modest. If you want to lose weight, go slow. Hard “cut” phases can wreck sleep and libido.
Weeks 4–0 before trying
Hold steady. Keep workouts consistent, keep bedtime consistent, and keep heat exposure to the groin occasional, not daily. If you and your partner are tracking cycles, learn the fertile window basics so timing feels calmer.
Medical prep that’s worth the appointment
A preconception visit for men is a risk check plus a meds review. It can also point you toward a semen analysis early if there’s a clear reason to test.
Bring these to the visit
- A full medication list (prescriptions, over-the-counter meds, supplements).
- Any past genital infections, surgeries, injuries, or undescended testicle history.
- Family history of inherited conditions or repeated miscarriages.
Ask about these topics
- Chronic conditions like diabetes, high blood pressure, thyroid disease, and sleep apnea.
- STI testing if either partner has had new partners since the last screen.
- Medication swaps if you use drugs linked to fertility, erections, or hormones.
- Workplace exposures like solvents, pesticides, heavy metals, or high heat.
If you want to see the full checklist clinicians usually cover before conception, ACOG’s page on prepregnancy care lays out common screening and counseling topics.
Habits that change sperm quality
Most men don’t need supplements or fancy testing to move the needle. Start with the basics and make them repeatable.
Nicotine and recreational drugs
Nicotine use is linked with poorer semen measures and longer time to pregnancy in many studies. Cannabis may also affect sperm and sexual function in some men. If you’re trying to conceive, the cleanest move is to stop both.
If you use opioids, stimulants, or other substances, get medical care early. Withdrawal and relapse cycles can wreck sleep and mood—two things you want stable while trying.
Alcohol
Heavy drinking is tied to lower testosterone and weaker semen quality in research reviews. If you drink, keep it modest and keep “big nights” rare.
Sleep and rest
Short sleep can lower testosterone and raise stress hormones. Set a fixed wake time, cut caffeine after lunch, and keep the room cool and dark. Small changes, repeated, beat a perfect plan you can’t keep.
Heat and tight compression
Sperm production runs best a bit cooler than core body temperature. Long hot baths, saunas, and laptops on the lap can raise scrotal temperature. If you’re trying, keep heat exposure occasional. If you wear tight compression all day, switch to looser gear part of the week.
Food patterns and body weight
A steady diet helps energy and hormones. Build meals around protein, fruits, vegetables, legumes, whole grains, and fats from fish, olive oil, nuts, and seeds. If you’re underweight or carrying a lot of extra fat, fertility can drop. Aim for gradual change with strength training and steady meals.
Testosterone, steroids, and “fertility boosters”
Testosterone therapy and anabolic steroids can shut down sperm production. If you’re on testosterone or have used steroids, tell your clinician before you start trying. Don’t stop prescribed hormones abruptly, yet do ask about options that protect fertility. Many “male fertility” supplement stacks also mix high doses of vitamins and herbs without good data. Save your money until your clinician recommends a specific nutrient based on diet or lab work.
Caffeine and hydration
Coffee is fine for most men, yet huge caffeine intake can wreck sleep and raise anxiety. If you need a rule, keep caffeine earlier in the day and track whether it pushes bedtime later. Drink water through the day and keep sugary energy drinks as a rare thing, not a daily habit.
Exercise without extremes
Moderate training helps circulation and weight control. Extreme endurance blocks, anabolic steroid use, and aggressive cutting cycles can crush testosterone and sperm. If you’re lifting, keep it consistent and skip performance-enhancing drugs.

The CDC’s page on planning for pregnancy is written for families and is a handy shared checklist.
Sex timing without turning it into homework
Timing mistakes are common. Keep it simple.
- Start sex on alternate days a few days before expected ovulation.
- If using ovulation tests, have sex the day of the positive test and the next day.
- If timing pressure kills erections, step back to “alternate days” and drop the apps for a week.
Avoid long gaps between ejaculations during the fertile window. Also avoid trying three times a day out of panic. Consistency beats intensity here.
Family history, genetics, and when tests make sense
Many couples won’t need genetic testing on the male side before trying. Still, flag these early at your visit:
- Known inherited conditions in either family.
- Repeated miscarriages in past pregnancies with a prior partner.
- Past chemo, radiation, or major testicular injury.
- Especially low sperm count in a prior test.
ACOG’s clinician guidance on prepregnancy counseling lists many of the screening topics that can come up before conception.
Preconception timeline checklist for men
This table is broad on purpose, so you can match it to your own start date.
| Time window | What to do | Why it helps |
|---|---|---|
| 12–10 weeks before trying | Book a checkup; list meds, supplements, and past illnesses | Find fixable issues early |
| 10–8 weeks | Quit nicotine; stop recreational drugs; keep alcohol modest | New sperm develop under cleaner conditions |
| 8–6 weeks | Set sleep schedule; add strength training 2–4×/week | Better rest and steadier hormones |
| 6–4 weeks | Shift meals toward whole foods; eat fish 1–2×/week | Better nutrient intake |
| 4–2 weeks | Reduce sauna/hot tub use; avoid laptops on lap | Lower scrotal heat during final maturation |
| 2–0 weeks | Learn fertile window basics; decide on ovulation tests | Better timing, fewer missed cycles |
| While trying | Log fevers, sleep, alcohol, and sex timing | Spot patterns you can change |
| After a positive test | Keep nicotine and drugs out; keep routines steady | Fewer abrupt habit swings |
When to get checked sooner
Many couples conceive within a year of regular unprotected sex. Earlier evaluation makes sense if any of these fit:
- You’re 40 or older.
- You’ve had a vasectomy reversal, testicular surgery, or undescended testicle history.
- You’ve had chemo or radiation.
- You’ve had mumps after puberty or repeated high fevers.
- Erections or ejaculation problems last for months.
If you and your partner have been trying for 12 months (or 6 months if your partner is 35+), ask for a fertility evaluation. A semen analysis is quick and often answers whether timing is the issue or sperm count/motility is the issue.
Common prep problems and what to do
This table helps you decide what to change at home and what to bring to a clinician.
| Issue | What to try first | When to seek care |
|---|---|---|
| Low libido or low energy | Sleep schedule, strength work, fewer late nights | Lasts 3+ months or comes with ED |
| Erectile dysfunction | Review sleep apnea, alcohol, and meds with a clinician | Sudden onset, pain, or heart risk factors |
| Frequent hot tub or sauna use | Pause for 2–3 months while trying | Trying 6–12 months with no pregnancy |
| Nicotine use | Quit plan; nicotine replacement if recommended | Can’t stop after two serious attempts |
| Cannabis or other drug use | Stop; ask for medical help if withdrawal is hard | Daily use or relapse cycles |
| Past STI or genital infection | Get tested and treated when needed | Testicular pain, swelling, or fever |
| High BMI or rapid weight gain | Slow loss with meals plus lifting; avoid crash dieting | Sleep apnea signs or diabetes symptoms |
| Chemo, radiation, or major surgery history | Ask about semen analysis before trying | Any concern about fertility preservation |
Make this easier on both of you
You can make a big difference without taking over. Handle a few chores, keep alcohol out of the house if your partner is avoiding it, and share the calendar note for the fertile window. Those small acts reduce friction and keep trying to conceive from taking over all conversations.
Once you’ve done the basics—checkup, nicotine out, sleep steady, alcohol modest—stick with them for a full 90 days. If pregnancy happens sooner, great. If it doesn’t, you’ll walk into the next step with cleaner data and fewer moving parts.
