Low sperm count treatment depends on the cause. Options range from lifestyle and dietary changes to hormone therapy, surgical correction, and assisted reproduction techniques like IVF and ICSI. The right approach for you depends on the underlying cause, the severity of the count, and how long you have been trying to conceive.
Whichever route you take, patience matters: new sperm take approximately 74 days to mature, so any change, whether a lifestyle adjustment, a supplement, or a course of medication, needs at least 3 months before its effect can be measured on a repeat semen analysis. This 3-month window is the minimum time to expect improvement, and it applies across the board.
A sperm count below 15 million per millilitre of semen is classified as oligospermia (Cleveland Clinic, Oligospermia, 2025). Severe oligospermia, where the count drops below 5 million per millilitre, typically requires more intensive medical treatment for low sperm count.
Having a low count does not mean pregnancy is impossible. Many men with reduced counts conceive naturally. But if you and your partner have been trying for 12 months without success (or 6 months if your partner is over 35), it is time to investigate and act.

What Causes Low Sperm Count?
Medical Causes
Varicocele is the single most common cause, affecting roughly 4 in 10 men diagnosed with low sperm count. A varicocele is a swelling of the veins that drain the testicle, raising the local temperature and impairing sperm production. It is usually painless, which means many men do not know they have one until fertility testing reveals the problem.
Hormonal imbalances affecting testosterone, follicle-stimulating hormone (FSH), or luteinising hormone (LH) can disrupt the signals that drive sperm production. Conditions like hypogonadism, thyroid disorders, or pituitary tumours fall into this category.
Infections of the reproductive tract, including sexually transmitted infections and urinary tract infections, can cause inflammation that damages sperm or blocks the tubes through which sperm travel.
Genetic conditions such as Klinefelter syndrome (47, XXY), Y chromosome microdeletions, and cystic fibrosis gene mutations can reduce or completely stop sperm production. Genetic testing is recommended when the count is very low or when azoospermia (no sperm at all) is diagnosed.
Retrograde ejaculation occurs when semen enters the bladder during orgasm instead of exiting through the penis. Diabetes, spinal injuries, and certain medications can cause this (Mayo Clinic, Low Sperm Count, 2024).
Lifestyle and Environmental Causes
Obesity (BMI above 30) is associated with approximately 30% lower sperm concentration and reduced testosterone. Smoking reduces sperm count by 10 to 30% and increases DNA fragmentation. Heavy alcohol use suppresses testosterone and disrupts sperm production. Recreational drug use, particularly anabolic steroids and cannabis, directly impairs spermatogenesis.
Heat exposure from prolonged hot baths, saunas, tight underwear, or laptop use on the lap raises scrotal temperature above the range needed for healthy sperm production.
Environmental toxins, including heavy metals (lead, cadmium, mercury) and industrial chemicals (pesticides, solvents), can damage sperm at the cellular level.
Medications such as testosterone replacement therapy, certain antidepressants (paroxetine, clomipramine), finasteride, methotrexate, and some anticonvulsants can reduce sperm count as a side effect. Never stop prescribed medication without consulting your doctor first.
How Low Sperm Count Is Diagnosed
Diagnosis starts with a semen analysis, which measures three core parameters: sperm concentration (count), motility (movement), and morphology (shape). The NHS recommends that if the first test shows a possible problem, a second analysis is performed approximately 3 months later to confirm, since sperm counts fluctuate naturally.
If both tests confirm low count, further investigation typically includes:
-
Hormone blood tests to check testosterone, FSH, LH, and prolactin levels
-
Scrotal ultrasound to identify varicocele or structural abnormalities
-
Genetic testing if the count is very low or zero
-
Post-ejaculation urinalysis to check for retrograde ejaculation
-
Sperm DNA fragmentation testing to assess the integrity of sperm DNA, which affects embryo development and miscarriage risk
At IVF Matters, male fertility testing includes semen analysis, semen culture, sperm DNA fragmentation assessment, hormonal profiling, genetic screening, and scrotal ultrasound. Dr Irfana Koita reviews results and builds a treatment plan based on the complete picture, not a single test result.
5 Proven Low Sperm Count Treatment Options
-
Lifestyle and Dietary Changes: The First Line of Treatment
For mild to moderate low sperm count with no identified structural or hormonal cause, lifestyle modification is the starting point. This is not a vague "eat better" recommendation. Specific changes can measurably affect sperm parameters.
Weight management. Losing excess weight through regular exercise and a balanced diet can improve both sperm count and testosterone levels. Even moderate weight loss in overweight men has been shown to improve semen quality.
Quit smoking and limit alcohol. Both have well-documented negative effects on sperm production. The NHS advises drinking no more than 14 units of alcohol per week, spread across 3 or more days.
Reduce heat exposure. Switch from tight underwear to loose-fitting boxers. Avoid prolonged hot baths and saunas. Do not rest laptops on your lap for extended periods.
Dietary improvements. Research consistently links Mediterranean-style diets (rich in fruits, vegetables, whole grains, fish, nuts, and olive oil) with higher sperm concentration and motility. Diets high in processed foods, trans fats, and added sugars are associated with poorer outcomes.
Antioxidant supplementation. Zinc, selenium, vitamin C, vitamin E, and CoQ10 all have evidence supporting their role in protecting sperm from oxidative damage. The benefit is strongest in men with existing nutritional deficiencies. Start supplementation at least 3 months before retesting, since new sperm take about 74 days to mature.
These changes are not a substitute for medical investigation, but they can make a meaningful difference, particularly when combined with one of the treatment options below. IVF Matters offers nutrition consultations tailored specifically to fertility, so any dietary plan is built around your test results rather than generic advice.
- Hormone Therapy for Low Sperm Count
When blood tests reveal a hormonal cause, targeted medication can restore the signals that drive sperm production.
Clomiphene citrate (used off-label in men) stimulates the pituitary gland to produce more FSH and LH, which in turn increase testosterone and sperm production in the testes. It is typically prescribed for men with low testosterone who want to preserve or improve fertility, since external testosterone replacement actually suppresses sperm production.
Gonadotropin injections (FSH and hCG) directly stimulate the testes to produce sperm. These are used in cases of hypogonadotropic hypogonadism, where the pituitary gland fails to produce adequate levels of the hormones needed for sperm production.
Stopping testosterone replacement therapy (TRT). If you are currently taking exogenous testosterone (injections, gels, or patches), this is likely suppressing your natural sperm production. Switching to clomiphene or gonadotropins under specialist supervision can allow sperm production to recover, though the process typically takes 6 to 12 months.
Hormone therapy requires specialist monitoring through regular blood tests and semen analyses to track response and adjust dosing.
- Surgical Treatment: Varicocele Repair and Obstruction Correction
Surgery is the appropriate low sperm count treatment when a physical problem is identified.
Varicocelectomy is the surgical repair of a varicocele. The procedure ties off or redirects the swollen veins, restoring normal temperature regulation in the scrotum. Studies show that varicocelectomy improves sperm count in about 70% of men and significantly increases pregnancy rates. It is typically performed as a day procedure under local or general anaesthetic.
Vasectomy reversal reconnects the vas deferens after a previous vasectomy. Success rates depend on how long ago the vasectomy was performed, with higher success rates when the reversal is done within 10 years.
Obstruction repair. Blockages in the epididymis or ejaculatory ducts can prevent sperm from reaching the semen. Microsurgical techniques can bypass or repair these blockages. If surgical repair is not possible, sperm can often be retrieved directly from the testicle or epididymis for use in IVF/ICSI.
Surgical sperm retrieval (TESA, MESA, or micro-TESE) is used when no sperm are present in the semen (azoospermia), but sperm production is occurring in the testes. The retrieved sperm are then used with ICSI to fertilise eggs in the laboratory.
-
IUI: Intrauterine Insemination for Mild Low Sperm Count
Intrauterine insemination (IUI) is a fertility treatment where prepared, concentrated sperm is placed directly into the uterus around the time of ovulation. By bypassing the cervix, IUI increases the number of sperm that reach the fallopian tubes.
IUI is most effective for men with mild low sperm concentration treatment needs, typically when the post-wash count (after laboratory preparation) is at least 5 to 10 million motile sperm. It is also used when motility rather than count is the primary issue, or when unexplained infertility is diagnosed alongside borderline sperm parameters.
IUI is less invasive and less expensive than IVF. At IVF Matters, the fixed-price IUI package is £3,000 and includes monitoring, medication, sperm preparation, and the insemination procedure.
IUI success rates per cycle are lower than IVF (typically 10 to 20% per cycle for mild male factor infertility), so most specialists recommend trying 3 to 6 cycles before considering IVF.
-
IVF and ICSI: Male Infertility Treatment for Moderate to Severe Cases
When low sperm count is too severe for IUI, or when other treatments have not worked, in vitro fertilisation (IVF) with intracytoplasmic sperm injection (ICSI) is the most effective male infertility treatment available.
How IVF with ICSI works for low sperm count:
-
The female partner undergoes ovarian stimulation to produce multiple eggs
-
Eggs are collected from the ovaries under sedation
-
A single healthy sperm is selected and injected directly into each mature egg using a fine needle (ICSI)
-
Fertilised eggs develop into embryos in the laboratory over 5 to 6 days
-
The strongest embryo is transferred to the uterus
ICSI is specifically designed for male factor infertility. It requires only one viable sperm per egg, making it effective even for men with severe oligospermia. When combined with advanced sperm selection techniques like ZyMot (which mimics natural sperm selection to identify the healthiest sperm), outcomes can be further optimised.
At IVF Matters, the fixed-price IVF package (£12,000) includes ICSI, ZyMot sperm selection, Embryoscope monitoring, all medication, unlimited monitoring scans, blastocyst culture, assisted hatching, embryo transfer, and one year of embryo storage. There are no hidden costs.
For men with very low or zero sperm counts, surgical sperm retrieval (described in option 3) can be combined with ICSI, meaning that even azoospermia does not necessarily rule out biological fatherhood.
Remedies for Low Sperm Count: What Works and What Does Not
The search for remedies for low sperm count often leads men to unproven supplements, herbal products, and online "sperm boosters." It is important to separate evidence-based approaches from marketing.
What has evidence behind it: zinc, selenium, vitamin C, vitamin E, CoQ10, and vitamin D supplementation (particularly when correcting a deficiency). A Mediterranean-style diet. Regular moderate exercise. Adequate sleep (7 or more hours). Stress management. Quitting smoking and reducing alcohol.
What does not have reliable evidence: proprietary "fertility blend" supplements with undisclosed ingredients, herbal remedies marketed without clinical trial data, and any product claiming to "double" or "triple" sperm count without specifying the mechanism or evidence base. This is also where most of the "fertility-maxxing" advice circulating online falls short: extreme supplement stacks, cold exposure protocols, and other social-media routines promising dramatic results are rarely backed by the kind of clinical evidence described above, and some (particularly high-dose, multi-supplement stacking) can do more harm than good.
What can actively harm sperm count: testosterone replacement therapy (suppresses natural production), anabolic steroids, excessive zinc supplementation (above 25mg daily), and high-dose antioxidants without medical guidance.
When to See a Specialist About Low Sperm Count
The NHS recommends seeing a GP if you and your partner have been trying for over 12 months without success (or 6 months if your partner is 36 or over). However, you do not need a GP referral to see a private fertility specialist.
You should consider seeing a specialist sooner if:
-
You have a known condition that affects fertility (varicocele, undescended testes, hormonal disorder)
-
You or your partner have had previous fertility issues or miscarriages
-
You are taking medication known to affect sperm production
-
You have noticed changes in sexual function (erectile difficulties, low libido, reduced ejaculate volume)
At IVF Matters, you can book directly without a referral. Same-week appointments are available, and the male subfertility page explains the full diagnostic and treatment pathway that Dr Koita follows for male factor cases.
Frequently Asked Questions
Can Low Sperm Count Be Permanently Cured?
It depends on the cause. Lifestyle-related low sperm count often improves significantly with sustained changes to diet, weight, and habits. Varicocele repair typically produces lasting improvement. Hormonal therapy works as long as the underlying condition is managed. Genetic causes of low sperm count cannot be reversed, but assisted reproduction (IVF/ICSI) can still achieve pregnancy using the sperm that is available.
How Long Does It Take for Low Sperm Count Treatment to Work?
Sperm production takes approximately 74 days, plus 10 to 14 days for maturation. Any treatment, whether lifestyle changes, supplements, or hormone therapy, needs at least 3 months before its effect shows up in a semen analysis. Surgical treatments like varicocelectomy typically show results in semen parameters within 3 to 6 months after the procedure.
Does Low Sperm Count Mean I Cannot Have Children?
No. Many men with low sperm counts conceive naturally, though it may take longer. For counts that are too low for natural conception, treatments like IUI, IVF, and ICSI offer effective pathways to biological fatherhood. Even men with no sperm in their semen (azoospermia) can sometimes father biological children through surgical sperm retrieval combined with ICSI.
Is Low Sperm Count Becoming More Common?
Research indicates that sperm counts in Western countries have declined by over 50% since 1973, and the decline appears to be continuing. Obesity, environmental toxin exposure, lifestyle factors, and increased average age at first attempt to conceive are all likely contributors. This trend makes early testing and proactive management more important than ever.
Can Stress Alone Cause Low Sperm Count?
Chronic stress raises cortisol levels, which can interfere with testosterone production and sperm development. While stress alone is unlikely to be the sole cause of clinically low sperm count, it can worsen existing issues and reduce overall semen quality. Addressing stress through exercise, sleep, and professional support is a reasonable part of any fertility improvement plan.
