ICSI (Intracytoplasmic Sperm Injection)
A single sperm is injected directly into an egg — commonly used for male factor infertility.
ICSI is typically recommended when sperm count, motility, or morphology may make natural fertilisation less likely, including in cases of male infertility. It is performed as part of an IVF cycle, with a single healthy sperm selected under a microscope and injected directly into a mature egg.

Azoospermia
Azoospermia is a condition characterised by the absence of sperm in semen. It falls into two broad types. Obstructive azoospermia is caused by a blockage along the reproductive tract — in the epididymis, vas deferens, or ejaculatory ducts — due to congenital abnormalities, infection, past surgery such as a vasectomy, or inflammation. Non-obstructive azoospermia instead reflects the testicles' inability to produce sufficient sperm, rooted in genetic factors, hormonal imbalances, the after-effects of chemotherapy or radiation, testicular injury, or certain medications. Distinguishing between the two guides which treatment path is appropriate.
