The investigation of severe oligoasthenoteratotterospermia (OAT) and azoospermia includes:
- Hormone test(FSH, LH, PRL, Testo, TSH),
- Testicular ultrasound with Doppler,
- Karyotype
- Test for micro- deletions in chromosome Y,
- Cystic fibrosis test
- Testicular biopsy and histological examination.
In special cases, collaboration with specialized urologists or endocrinologists in the diagnosis and treatment of male infertility is beneficial.
