The short answer is yes, but probably not the ones you're thinking of.
When most men hear "sexual practices and fertility," they picture timing intercourse perfectly, certain positions, or maybe some ancient Tantric technique. The research tells a different story. What actually moves the needle on sperm quality and conception probability has more to do with what you don't do in bed-and how you handle the days leading up to it.
Let's walk through what the science says, what's just folklore, and what you can actually use.
Frequency matters more than timing
The single most impactful sexual practice for male fertility is how often you ejaculate in the days before trying to conceive.
Conventional wisdom says "save it up" for the fertile window. That advice is wrong for most men.
Sperm that sit in the epididymis (the storage tube behind each testicle) for more than a few days accumulate DNA damage from oxidative stress. A 2015 study in the journal Fertility and Sterility found that men who ejaculated daily for seven days had significantly lower sperm DNA fragmentation than men who abstained for three days or longer. The trade-off is that total sperm count per ejaculate drops slightly with daily ejaculation, but the quality-motility, morphology, and DNA integrity-improves.
For couples trying to conceive, the research supports ejaculating every 24 to 48 hours during the fertile window. That gives you enough sperm volume while keeping DNA damage low. Some reproductive urologists now recommend daily ejaculation for the five days leading up to ovulation, then every other day after.
If you've been told to "save up" for the big day, that advice is outdated.
Abstinence windows: the Goldilocks zone
There is a sweet spot for how long you should wait between ejaculations when optimizing for fertility.
Too short (under 12 hours) and sperm count hasn't recovered. Too long (over 7 days) and DNA fragmentation climbs, motility drops, and the sperm that do come out are older and more damaged.
The World Health Organization's manual for semen analysis recommends 2 to 7 days of abstinence as the standard for testing. But for actual conception, the evidence points to a narrower window.
A 2020 meta-analysis in Andrology looked at 25 studies and found that sperm motility and DNA integrity were best at 1 to 3 days of abstinence. Beyond 4 days, quality declined. The sweet spot for most men appears to be 24 to 48 hours between ejaculations when actively trying to conceive.
If you and your partner are tracking ovulation, plan your timing around this window. Skip the "save it up" strategy.
Lubricants: the hidden variable most men ignore
This is the practice question nobody asks, but it matters.
Most commercial lubricants are toxic to sperm. A study published in Fertility and Sterility tested nine common lubricants and found that all of them significantly impaired sperm motility within 30 minutes of exposure. Some reduced motility by 60 to 100 percent.
The worst offenders are lubricants containing glycerin, propylene glycol, or parabens-which is most of what you'll find at a drugstore. These ingredients create an osmotic environment that kills sperm on contact.
If you need lubrication, the safest options are:
- Mineral oil (plain, unscented)
- Canola oil
- Pre-seed or similar fertility-friendly lubricants (these are formulated to match the pH and osmolality of fertile cervical mucus)
- Saliva is better than commercial lube, but not ideal-it has enzymes that can damage sperm over time
Skip the "warming" or "tingling" varieties entirely. Those contain chemicals designed to create sensation, not protect sperm.
Position and depth: the evidence is thin
You'll find plenty of advice online about which sexual positions maximize fertility. The research is not convincing.
A 2017 study in the Journal of Sexual Medicine found no significant difference in pregnancy rates between couples who used the missionary position versus other positions. What mattered more was whether ejaculation occurred deep in the vagina, close to the cervix.
The practical takeaway: any position that allows for deep penetration at the moment of ejaculation is fine. There is no "magic position" for fertility.
The one exception is positions that allow gravity to work against you-like female-on-top immediately after ejaculation. There is some evidence that staying supine for 15 to 20 minutes after intercourse improves sperm transport, but the data is mixed. It won't hurt, and it might help, but don't stress about it.
The scrotal temperature factor (yes, it applies here)
This is the fertility practice that connects directly to your bedroom habits.
Testicles need to be 2 to 4 degrees Celsius cooler than core body temperature to produce healthy sperm. Anything that raises scrotal temperature for prolonged periods reduces sperm quality for the next 60 to 90 days.
What does this mean for sexual practices?
- Hot baths or hot tubs before sex: bad idea. Scrotal temperature spikes within minutes.
- Laptop on your lap while you watch something before bed: same problem.
- Tight underwear or compression shorts during sleep: possibly problematic if you run hot.
The most practical intervention: sleep naked or in loose boxers. A 2018 study in Human Reproduction found that men who slept naked had lower scrotal temperatures and better sperm quality than men who wore underwear to bed.
If you're trying to conceive, treat your testicles like delicate cargo for the two to three months leading up to it. That means no hot baths, no sauna sessions (sorry), and loose clothing when possible.
Stress and the bedroom
This one is harder to measure but just as real.
Psychological stress elevates cortisol, which suppresses the hypothalamic-pituitary-gonadal axis-the hormone chain that controls testosterone and sperm production. Chronic stress is associated with lower sperm concentration, motility, and normal morphology.
The sexual practice angle: if sex becomes a chore focused entirely on conception, performance anxiety can spike cortisol further. Couples who track ovulation obsessively and schedule intercourse with clinical precision often report lower sexual satisfaction and higher stress.
The research suggests that maintaining some spontaneity-or at least not turning every sexual encounter into a fertility test-improves outcomes. A 2019 study in Psychoneuroendocrinology found that men who reported higher sexual satisfaction had better sperm parameters, independent of frequency.
Practical advice: keep sex connected to pleasure, not just procreation. If you're tracking ovulation, still have sex for fun during the non-fertile window. It keeps the pressure off and the hormones balanced.
The orgasm itself
There is one more practice question worth addressing: does the intensity or quality of orgasm affect sperm quality?
The data says no. Sperm parameters are determined by what happened in the testicles and epididymis over the preceding weeks, not by the experience of ejaculation itself. A quick, unremarkable orgasm delivers the same sperm as a prolonged, intense one.
What does matter is whether you actually ejaculate. Retrograde ejaculation (when semen goes into the bladder instead of out the urethra) is a real condition that affects some men, particularly those with diabetes, spinal cord injuries, or a history of prostate surgery. If you notice dry orgasms or very low semen volume, that is a conversation for a urologist, not a blog post.
What to do with this information
If you're trying to conceive, here is the short version:
- Ejaculate every 24 to 48 hours during the fertile window. Do not abstain for more than 3 days.
- Use a fertility-friendly lubricant or none at all. Check the label.
- Keep your testicles cool for the 2 to 3 months leading up to conception. No hot baths, no sauna.
- Do not stress about position. Deep penetration at ejaculation is enough.
- Keep sex enjoyable, not just functional. Your hormones will thank you.
None of this replaces a conversation with a reproductive urologist or fertility specialist. If you and your partner have been trying for 12 months (or 6 months if she is over 35) without success, get a semen analysis and a full workup. The practices above can optimize good sperm, but they cannot fix underlying medical issues.
