Male infertility is a clinical diagnosis. It is pretty much the only reason for a testicular biopsy.
This article focuses on the testicular causes of infertility. Testicular biopsy redirects to here.
General
- Infertility is a clinical diagnosis.
It can be divided into:[1]
- Pre-testicular - e.g. hormonal, pituitary.
- Testicular.
- Post-testicular - e.g. blockage of vas deferens.
Microscopic
Male infertility on testicular biopsy shows one the following patterns:[1]
- Normal testis.
- Hypospermatogensis.
- Maturation arrest.
- Sertoli cells only.
- Seminiferous tubule hyalinization
- A combination of the above.
DDx:
- Intratubular germ cell neoplasia.
- Germ cell tumour.
- Testicular adrenal rest tumour in the context of congenital adrenal hyperplasia - case report.[2]
- Inflammation of the testis.
Sign out
- The diagnosis should be the pattern (#1-6 above).
The following should be commented on:
- The number of tubules.
- The number of tubules with sperm.
- Hyalinization of the tubules.
- Inflammation.
- Absence of intratubular germ cell neoplasia.
Mixed pattern
LEFT TESTIS, BIOPSY FOR SPERM RETRIEVAL: - SERTOLI CELLS ONLY REGIONS (25% OF BIOPSY) INTERMEIXED WITH HISTOLOGICALLY NORMAL TESTIS (75% OF BIOPSY) WITH NORMAL NUMBERS OF SPERM. - NEGATIVE FOR SIGNIFICANT SEMINIFEROUS TUBULE HYALINIZATION. - NEGATIVE FOR SIGNIFICANT INFLAMMATION. - NEGATIVE FOR INTRATUBULAR GERM CELL NEOPLASIA.
