Inhibin A & B

Alias: N/A

Discipline: Clinical Chemistry

Test information: The major clinical use of the inhibin A and B assays are in the diagnosis and treatment monitoring of granulosa and sertoli cell tumours. Levels of inhibin A in women with granulosa cell tumours of the ovary have been shown to be elevated. Inhibin B in neonates may be used to aid in cases with ambiguous genitalia. Higher levels are observed in babies with functional testes. Inhibin B is the most common inhibin to be found in males. Prior to puberty inhibin B levels are low, whilst during puberty levels increase. Adults males that have impaired spermatogenesis have been shown to have low inhibin B levels alongside elevated FSH. Therefore proposed as a marker for male fertility.
