Oligospermia — a sperm concentration below the reference range — is one of the most common findings in male infertility. Treatment starts with identifying the cause, because the correct next step is frequently urological or hormonal rather than regenerative.
Medical treatments for low sperm count
A structured andrology work-up comes first: repeat semen analysis, hormone profile (FSH, LH, testosterone, prolactin), scrotal ultrasound, infection screening and, where indicated, genetic testing. Depending on the finding, established options include varicocele repair, treatment of infection, hormonal therapy, lifestyle and medication review, and assisted reproduction such as IUI, IVF or ICSI.
- Varicocele correction where a clinically significant varicocele is present
- Antibiotic treatment for genital tract infection
- Hormonal therapy in hypogonadotropic hypogonadism
- Withdrawal of gonadotoxic medication or exogenous testosterone
- Assisted reproductive techniques, including ICSI for severe oligospermia
Can stem cell therapy help male infertility or low sperm count?
Mesenchymal stem cell therapy is not an approved treatment for male infertility, low sperm count or azoospermia. Direct controlled evidence in andrology is very limited. Established care — hormonal assessment, urological workup, lifestyle modification, varicocele repair where indicated, and assisted reproduction with ICSI or surgical sperm retrieval — has evidence and clear pathways. Regenerative options here are considered only alongside a reproductive-medicine specialist.
Key facts
- Approval status
- Not approved for male infertility
- Evidence
- Very limited controlled data
- Standard care
- Andrology workup, varicocele repair where indicated, ICSI/TESE
What we know
- ICSI with surgical sperm retrieval (TESE/micro-TESE) has established results in selected patients with azoospermia.
What remains uncertain
- Whether MSC administration produces reproducible sperm-parameter change compared with placebo.

A plain summary of what the published research does and does not show for this condition. It is written to the same standard whether the evidence is strong or weak.
- Human studies available?
- Yes — early-stage only
- Randomised trials?
- Very few controlled human studies
- Main outcomes studied
- Sperm concentration and motility

- Regulatory approval for this indication
- United States (FDA): No FDA-approved mesenchymal stem cell product for this indication. The FDA has issued consumer warnings about unapproved stem cell products.
- European Union (EMA): No EMA-authorised mesenchymal stem cell medicine for this indication.
- United Kingdom (MHRA): No MHRA-authorised mesenchymal stem cell medicine for this indication.
- Türkiye (Ministry of Health): In Türkiye, cell therapies are delivered only inside Ministry of Health–licensed centres under the regenerative medicine / advanced therapy regulations, as clinical research or individual (exceptional) use — not as an approved routine treatment for this indication.
- Role at our centre

Where regenerative approaches fit
Research into mesenchymal stem cells and their secretome in non-obstructive azoospermia and idiopathic oligospermia is early-stage. It is discussed as an adjunct in selected cases where standard options have been exhausted and the patient understands the evidence is preliminary. It is never offered as a replacement for a fertility work-up or for ICSI.

What a consultation covers
Two semen analyses at least two weeks apart, hormone results, ultrasound findings, prior treatments and your partner's fertility assessment. We will state clearly whether a regenerative discussion is even appropriate, or whether andrology and IVF referral should take priority.
Frequently asked questions
Can stem cells cure low sperm count?
No. Evidence is preliminary and no regenerative therapy is established as a treatment for oligospermia. Standard andrology and assisted reproduction remain the primary routes.
How long before a semen analysis changes after treatment?
Spermatogenesis takes roughly 72–90 days, so any repeat analysis is scheduled at least three months later.
Does testosterone therapy help?
Exogenous testosterone usually suppresses sperm production and can worsen infertility. It should be reviewed by an andrologist.
