Peripheral concentrations of gonadotrophins and sexual steroids in infertile males.

Relationships between the spermiogram and sex hormones in 104 andrologic patients were studied. Endocrine connections in normal and in pathologic spermiogenesis have been studied. A rather close correlation was found between FSH and ICSH levels. ICSH increases parallel with the increase of FSH level. There is also a close relationship between sperm concentration and FSH level. Between ICSH and sperm count the correlation is not significant. Between steroid hormone level and sperm concentration no correlation ws found. It is only the plasma FSH level which show a close relationship with the disorder of spermiogenesis and it has diagnostic significance.
