Male Fertility Surgery

Varicocele repair

A varicocele is an enlargement of veins within the scrotum that raises testicular temperature and impairs sperm production. Varicocelectomy is most commonly performed using the microsurgical subinguinal approach, which has the lowest recurrence rate and least risk of damage to testicular arteries and lymphatics. The procedure is indicated when a clinically detectable varicocele coincides with abnormal semen parameters and no female factor requiring immediate IVF is present.

Improvement in sperm count and motility is gradual -- a full spermatogenesis cycle takes approximately 74 days. Follow-up semen analysis is typically scheduled at three months. Not all patients see measurable improvement; the decision to operate versus proceed to IVF with ICSI is a clinical judgment based on semen severity, female partner age, and time constraints.

Surgical sperm retrieval

When no sperm are present in the ejaculate (azoospermia), sperm may still be obtainable directly from the reproductive tract. The choice of technique depends on whether the azoospermia is obstructive or non-obstructive:

1. Micro-TESE: microsurgical examination of seminiferous tubules under magnification to locate areas with active sperm production; preferred for non-obstructive azoospermia
2. TESE: testicular tissue biopsy examined for the presence of sperm
3. PESA: percutaneous epididymal sperm aspiration, a needle-based technique for obstructive azoospermia
4. TESA: testicular sperm aspiration, a needle-based alternative to open biopsy
5. MESA: microsurgical epididymal sperm aspiration, used for obstructive cases requiring a more precise approach

Retrieved sperm are used with ICSI in IVF. Obstructive azoospermia generally yields better retrieval outcomes than non-obstructive. Diagnostic testicular biopsy is performed when sperm production status is unknown and retrieval viability needs to be confirmed before planning treatment.

Vasectomy reversal

Vasectomy reversal re-establishes sperm flow following a prior vasectomy. Vasovasostomy reconnects the vas deferens where blockage is at the vas level. Vasoepididymostomy, a more technically demanding procedure, is required when blockage has occurred at the epididymis -- more common after longer intervals since vasectomy. Success rates decline with the length of time since the original procedure.

Couples comparing reversal against IVF with surgical retrieval should consider the female partner's age and ovarian reserve, the reversal success probability based on years since vasectomy, and the relative timelines and costs. Both a fertility specialist and a urologist should be consulted before deciding.

Other male fertility surgical procedures

Less common indications include repair of ejaculatory duct obstruction, where blockage prevents sperm from reaching the urethra and is typically treated by transurethral resection. Hypospadias affecting sperm deposition may require surgical correction where it directly contributes to infertility. Vas deferens abnormalities -- including congenital bilateral absence -- are evaluated for surgical feasibility; in many cases, sperm retrieval and IVF is the more appropriate path.

Male fertility surgery across countries

Procedures, legal frameworks, and IVF coordination logistics vary by destination. Key differences include Thailand's prohibition on the export of sperm, eggs, and embryos; Denmark's requirement for genetic testing before micro-TESE for non-obstructive azoospermia; and Malaysia's availability of all surgical procedures regardless of the IVF eligibility rules that apply specifically to donor egg cycles.
