Azoospermia

Plain-English guide for patients and families.

Azoospermia means no sperm are found in semen after centrifugation on at least two analyses. It is split into obstructive (sperm production may be normal but blocked) and non-obstructive (production in the testes is reduced or absent). Treatment may include surgical sperm retrieval plus ICSI.

Diagnosis pathway

Repeat semen analysis, hormone profile (FSH, testosterone, LH), examination, and sometimes genetic tests (e.g. CFTR in congenital absence of the vas deferens, karyotype/Y microdeletions in severe non-obstructive cases). Imaging or specialist referral completes the picture.

Treatment directions

Obstructive cases may be treated with reconstructive surgery or sperm retrieval from the epididymis/testes. Non-obstructive cases may use Micro-TESE to find pockets of sperm for ICSI. Donor sperm is an option when agreed by the couple after counselling.

Educational

Azoospermia affects approximately 1% of all men and about 10–15% of men presenting with infertility. Despite the alarming diagnosis of "zero sperm," modern microsurgical techniques like Micro-TESE can retrieve sperm in up to 50–60% of non-obstructive cases, enabling biological fatherhood through ICSI.

Key Points

Azoospermia is classified into obstructive (OA) and non-obstructive (NOA) — treatment differs significantly between the two.
Obstructive azoospermia often has excellent sperm retrieval rates since sperm production is typically normal.
Micro-TESE retrieval rates in NOA range from 30–60% depending on the underlying cause.
Genetic testing (karyotype, Y-microdeletion, CFTR) is essential before surgical retrieval to guide prognosis and counselling.
Even with very few sperm retrieved surgically, ICSI can achieve pregnancies with good outcomes.

Who Should Know This?

Men with zero sperm on semen analysis, couples facing male factor infertility, men with a history of undescended testes, prior chemotherapy, or known genetic conditions affecting fertility.

Clinical Context in Pakistan

Azoospermia management requires an integrated approach combining andrology, genetics, and IVF laboratory expertise. Dr. Adnan Jabbar at IVF Experts Lahore offers comprehensive azoospermia evaluation including hormonal workup, genetic testing, and coordination with microsurgical sperm retrieval and ICSI.
