Male Fertility and Sperm Increase: How to Improve Sperm Count and Quality

How to Improve Sperm Count and Male Fertility: A Practical Guide

When couples struggle to conceive, attention often turns first to the woman's health. But male factors contribute to roughly half of all infertility cases, either alone or alongside female factors. In many cases, an underlying factor can be identified and addressed. Understanding what affects sperm health — and what may genuinely help improve it — is one of the most useful things a man can do when planning for a family.

This guide covers the main causes of reduced male fertility, evidence-based ways to support sperm count and quality, and how testing at PULSE Clinic can provide clear answers rather than guesswork.

How Common Is Male Infertility?

Infertility affects a significant number of couples worldwide, and male factors are involved in roughly 40–50% of cases, either alone or alongside a female-factor cause. Despite this, male fertility tends to receive far less attention. Many men only consider testing after months, or even years, of unsuccessful attempts to conceive.

Testing earlier, rather than later, can help identify potential problems sooner and provide a clearer path towards appropriate treatment or further evaluation.

What Affects Male Fertility?

Sperm health depends on a combination of physical, hormonal, genetic, environmental, and lifestyle factors. Common contributors include:

• Varicocele — enlarged veins in the scrotum that can increase testicular temperature and affect sperm production. Varicocele is one of the more common potentially correctable causes of male infertility.
• Hormonal imbalances, including problems affecting testosterone, follicle-stimulating hormone (FSH), luteinising hormone (LH), or thyroid function.
• Infections, including certain sexually transmitted infections (STIs) that can cause inflammation or, in some cases, scarring within the reproductive tract.
• Lifestyle factors, such as smoking, heavy alcohol use, anabolic steroid use, chronic stress, and poor sleep.
• Heat exposure — prolonged exposure to high temperatures, such as frequent hot tubs or saunas, may affect sperm production. Evidence around everyday clothing choices is less clear.
• Higher body weight — excess body fat is associated with hormonal changes and poorer semen parameters in some studies.
• Environmental exposures, including certain pesticides, heavy metals, and industrial chemicals.
• Genetic conditions, such as Klinefelter syndrome, although these are less common.
• Certain medications, or a history of chemotherapy or radiation treatment.

In many cases, more than one factor may be involved. This is why a proper medical evaluation, rather than self-diagnosis, is the most reliable place to start.

How Is Male Fertility Assessed?

The starting point for most men is a semen analysis, sometimes called a sperm count test. This test evaluates several aspects of semen and sperm health, including:

1. Sperm count — the number or concentration of sperm in the sample.
2. Motility — how well the sperm move, which is important for their ability to travel through the female reproductive tract.
3. Morphology — the size and shape of the sperm.

Depending on the results and medical history, your doctor may recommend additional tests, such as a hormone panel including testosterone, FSH, and LH, or STI/PCR screening to identify or rule out potential underlying causes.

At PULSE Clinic, semen analysis and related fertility testing are available with confidential, judgement-free service. Our doctors can help explain what your results mean rather than leaving you with a laboratory report full of unfamiliar numbers.

Evidence-Based Ways to Support Sperm Count and Quality

Not every cause of low sperm count can be reversed through lifestyle changes alone. However, several healthy habits are associated with better sperm and semen parameters:

• Maintain a healthy weight: Excess body fat is associated with hormonal changes that may affect sperm production and quality.
• Limit alcohol and avoid smoking: Both smoking and heavy alcohol consumption have been associated with poorer sperm count and motility.
• Manage heat exposure: Avoid prolonged exposure to high temperatures, such as frequent hot tubs and saunas, particularly if you are actively trying to conceive.
• Exercise regularly, but avoid overtraining: Moderate physical activity supports overall health, while excessive training may affect reproductive hormones in some men.
• Prioritise sleep and manage stress: Poor sleep and chronic stress may affect the hormonal processes involved in sperm production.
• Eat a nutrient-dense, balanced diet: Diets rich in fruits, vegetables, whole grains, lean protein, and healthy fats provide nutrients that support overall reproductive health.
• Consider targeted supplementation where appropriate: Certain nutrients, including zinc, vitamin D, CoQ10, and folate, have been studied for their potential effects on sperm health. However, results vary, and supplements are not a guaranteed treatment for infertility. Where a deficiency is suspected, supplementation should be guided by appropriate testing and medical advice.

Because sperm production and maturation take roughly 2–3 months, it may take at least three months for lifestyle or supplement changes to be reflected in a follow-up semen analysis.

When to See a Doctor

Consider booking a fertility evaluation if:

• You and your partner have been trying to conceive for 12 months without success, or for 6 months if your partner is over 35.
• You've noticed symptoms such as testicular pain, swelling, or a lump.
• You have a history of an untreated STI, mumps after puberty, or a groin or testicular injury or surgery.
• You have concerns about your fertility or simply want a baseline assessment before starting a family.

Early testing does not necessarily mean something is wrong. For many men, it is simply a way to understand their reproductive health and plan with greater confidence.

How PULSE Clinic Can Help

PULSE Clinic offers a discreet, comprehensive approach to male reproductive health, including:

• Semen analysis (sperm count test) to assess sperm count, motility, and morphology
• PCR-based STI screening panels to identify infections that could potentially affect reproductive health
• Hormone testing where clinically indicated
• Doctor consultations to interpret your results and develop a personalised plan, whether that involves lifestyle changes, treatment for an underlying condition, or referral for further fertility care

Our approach is straightforward: no judgement, no unnecessary tests, just clear information and a plan tailored to your situation.

Frequently Asked Questions

How long should we try to conceive before getting tested?

Most doctors recommend seeking a fertility evaluation after 12 months of regular, unprotected intercourse without conception, or after 6 months if your partner is over 35. If you have known risk factors or concerns about fertility, testing sooner may be appropriate.

Can low sperm count be improved?

In many cases, sperm count or other semen parameters can improve when an underlying cause is identified and addressed. Depending on the cause, this may involve lifestyle changes, treatment for an infection or hormonal problem, or, in some cases, surgical treatment for conditions such as varicocele. However, not every case is reversible, and improving semen parameters does not always guarantee pregnancy.

Is semen analysis painful or invasive?

No. Semen analysis is non-invasive. The sample is collected privately, and your doctor can explain the collection process and when you can expect your results.

Do STIs really affect fertility?

Some STIs can affect reproductive health. Infections such as chlamydia and gonorrhoea, particularly when left untreated, may cause inflammation and complications that can affect the reproductive tract. Many STIs cause no obvious symptoms, which is why screening can be important even when you feel well.

Should both partners be tested?

Yes, fertility problems can involve either or both partners. When appropriate, evaluating both partners can provide a clearer picture of potential factors affecting conception and help guide the next steps.
