How long does sperm regenerate?

The division of cells: Two diploid sperm cells differentiate into two haploid sperm cells.

People with testes produce around 1,500 sperm per second.

The maturing stage: Spermatids mature into spermatozoa. It takes about 30 to 40 days.

That might sound like a lot, but a healthy person might release 80 to 300 million.

How does ejaculation affect sperm health?

There are many myths and misconceptions that surround male fertility.

That is simply not true–frequent ejaculation won’t make you infertile.

On average, each ejaculation will produce approximately 1.5 to 5.0 milliliters of liquid.

When you ejaculate, your body doesn’t release all of the sperm that’s being stored.

Research shows that the sperm count does decrease with each ejaculation.

How do we determine sperm health?

Sperm health is determined through a semen analysis of the sperm.

Sperm count: How many sperm are in semen? Higher count = better chances of fertilization. Sperm motility: How well sperm moves affects chances of reaching an egg. Sperm morphology: Shape of sperm signals health. Semen viscosity: Consistency allows sperm to move easily. Semen volume: Amount of semen per ejaculation.

Tips on how to increase sperm count and health for fertility

If you’re on a fertility journey and are looking for ways to improve your chances, there are things you can do to help boost your sperm health.

Lead an active lifestyle

Research shows that exercise helps increase your sperm count and improve sperm motility. One study found that men who did outdoor activities or lifted weights for 3.2 hours every week had sperm counts up to 42% higher than men who didn’t exercise.

Maintain a healthy diet

What we put in our bodies also impacts sperm health. Research shows that a balanced, healthy diet with fresh foods may positively affect semen and sperm quality.

Researchers suggest that consuming lots of saturated and trans fats through processed foods and red meat might negatively impact sperm structure.

Limit alcohol consumption

Lower your alcohol intake or quit completely. High alcohol consumption lowers semen volume and lowers testosterone levels, important for health and fertility.

Research shows that regular high alcohol consumption may negatively impact sperm concentration, total sperm count, and sperm morphology.

Quit smoking

Smoking is another popular poor habit that can cause many health issues, including problems with fertility. Research shows that smoking has a negative effect on sperm count, shape, and size.

Other ways to improve your chances of conception

Aside from making significant lifestyle changes to improve your chances of conception naturally, you may want to consider these practical tips as well:

Take a break between ejaculations

While we already touched on how ejaculation affects fertility and busted the myth that frequent ejaculation doesn’t negatively impact your fertility, there’s research that suggests waiting longer in between ejaculations to boost your chances of conception.

Waiting one to three days between ejaculations may lead to increased semen volume, sperm concentration, motility, and total sperm count, which can lead to higher chances of conception.

Don’t go overboard with it, though – abstaining from ejaculation for too long is not healthy, either. Studies show that the longer the sperm is stored, the higher the chances of developing DNA damage, which can lower sperm quality.

Have sex regularly during the fertile window

The thing that will make the biggest impact on your chances of conception naturally is having regular sex during the fertile window of your partner’s cycle.

Ovulation happens somewhere in the middle of the cycle and offers a fairly small window when the egg is released and viable for fertilization by sperm. You may want to ensure you have frequent intercourse before and during ovulation as sperm may live up to 3 to 5 days inside the female genital tract.

If you’re not certain about the best time to have sex, you may want to consider at-home ovulation tests that can help detect when your partner is in their fertile window.

The bottom line

Every day, your body produces around 1,500 sperm every second. However, the full sperm regeneration cycle for the sperm to fully mature is a long process and can take up to 74 days.

How long it takes for the sperm to regenerate will depend on many factors, such as age and lifestyle. You can slightly influence the health of your sperm with positive changes to your lifestyle, such as:

Exercise more Eat a healthy and balanced diet Limit alcohol consumption Avoid smoking

Understanding sperm health and the regeneration cycle is important for everyone, but mostly for those who are trying to conceive. You may slightly increase your chances of conception if you take breaks between ejaculation (1-3 days), and ensure you’re having sex during your partner’s fertile window.
