Varicocele — enlarged veins in the scrotum — is the most common correctable cause of male infertility, present in 35–40% of men with fertility problems. At Mother Hospitals, Boduppal, Dr. E. Prashanthi Reddy evaluates and treats varicocele through microsurgical varicocelectomy and/or IVF with ICSI. Call 97059 93366 for a male fertility evaluation.

The most common correctable cause of male infertility — found in 35–40% of infertile men
A varicocele is an abnormal enlargement of the veins that drain the testicles — the pampiniform venous plexus. Think of it as varicose veins in the scrotum. Blood that should flow out of the testicle pools in these dilated veins instead, raising scrotal temperature and damaging sperm production.
Varicocele is found in 15% of all men — but in 35–40% of men with primary infertility and up to 80% of men with secondary infertility (can't have a second child). It is the single most common correctable cause of male infertility.
Most varicoceles occur on the left side (because of the angle at which the left testicular vein drains into the left renal vein). Bilateral varicocele (both sides) occurs in 15–20% of cases and has a more severe effect on sperm production.
Three mechanisms by which varicocele damages sperm quality
Pooled blood in dilated veins warms the scrotum — sperm production needs temperatures 2–3°C below body temperature. Even 1–2°C excess impairs spermatogenesis significantly.
Impaired venous drainage increases reactive oxygen species (free radicals) that damage sperm DNA, reduce motility, and cause abnormal morphology — sperm DNA fragmentation.
Varicocele reduces testosterone production by impairing Leydig cell function. Lower testosterone further suppresses sperm production and libido.
Venous stasis (blood pooling) reduces oxygen and nutrient delivery to the testicle — in severe long-standing varicocele, this causes testicular atrophy (shrinkage).
Complete male fertility evaluation — semen, hormones, and scrotal ultrasound
Complete semen parameters including count, motility (progressive and total), morphology (Kruger strict criteria), volume, and pH. Repeat test if abnormal, to confirm findings.
Confirms varicocele diagnosis, grades its severity (Grade 1–3), and identifies which side(s) are affected. The gold standard imaging for varicocele — detects subclinical varicocele not palpable on examination.
FSH, LH, testosterone, prolactin — assesses testicular function and hypothalamic-pituitary axis. Elevated FSH with low testosterone suggests significant testicular damage.
DFI (DNA Fragmentation Index) — identifies oxidative DNA damage to sperm that standard semen analysis misses. Important for couples with recurrent IVF failure or recurrent miscarriage despite normal semen parameters.
Surgery vs IVF with ICSI — personalised recommendation based on your case
| Factor | Microsurgical Varicocelectomy | IVF with ICSI |
|---|---|---|
| Best for | Younger couples, mild-moderate male factor, no female factor | Female age >35, combined male+female factor, severe azoospermia |
| Timeline to pregnancy | 6–18 months (sperm improves over 3–12 months) | 2–4 months per IVF cycle |
| Natural conception | Yes — 30–40% natural pregnancy rate post-surgery | No — assisted reproduction required |
| Success rate | Sperm improves in 60–70%; pregnancy in 30–40% | 40–60% per cycle (depends on female age/AMH) |
| Advantage | Restores natural fertility long-term; lower cost | Faster; works regardless of sperm severity |
| Procedure | Day surgery — 2–3 cm incision under microscope | Egg retrieval + ICSI in lab + embryo transfer |
Dr. E. Prashanthi Reddy evaluates both partners together and recommends the most efficient path to pregnancy for your specific situation.
Answered by Dr. E. Prashanthi Reddy
What is a varicocele?
Enlarged, dilated veins in the scrotum that drain the testicles — similar to varicose veins in the legs. Varicocele is the most common correctable cause of male infertility, present in 35–40% of infertile men.
How does varicocele cause infertility?
By raising scrotal temperature (pooled blood transfers heat to the testicle), increasing oxidative stress (free radical damage to sperm), reducing testosterone, and impairing blood flow. Result: low sperm count, poor motility, abnormal morphology, and elevated sperm DNA fragmentation.
Can varicocele cause azoospermia (zero sperm)?
Yes — severe bilateral varicocele can cause non-obstructive azoospermia. Varicocelectomy restores sperm to the ejaculate in 30–50% of azoospermic men with varicocele. For those who don't respond, surgical sperm extraction (TESA/micro-TESE) with IVF/ICSI is available.
Is surgery always needed for varicocele?
Not always. Men with varicocele but normal semen analysis and fertile partners may not need surgery. Treatment is recommended when varicocele is clinical (detectable), semen analysis is abnormal, and the couple is trying to conceive. IVF/ICSI is an alternative to surgery for suitable couples.
How long after varicocelectomy does sperm improve?
Sperm improves from 3 months post-surgery and continues for up to 12 months. Semen analysis at 3 and 6 months monitors progress. Spontaneous pregnancy rates of 30–40% are achieved within 1–2 years after successful repair.
Can varicocele come back after surgery?
Recurrence rate is lowest with microsurgical subinguinal varicocelectomy (under 1–2%) — which is why it is the gold standard. Laparoscopic varicocelectomy has a higher recurrence rate (5–15%). Open high ligation has the highest recurrence. Dr. E. Prashanthi Reddy refers surgical cases to experienced urological surgeons for optimal outcomes.
What is the cost of varicocele treatment in Hyderabad?
Semen analysis, scrotal Doppler ultrasound, and hormonal panel are affordably priced at Mother Hospitals. Varicocelectomy surgery cost and IVF/ICSI package pricing are available on request. Call 97059 93366 for a detailed quote.
