ABSTRACT
Effects of adrenalectomy and administration of gonadotropins on cell counts of different cell types of spermatogenesis and morphology of the Leydig cells were studied in 30 day old mice. Adrenalectomy (duration, 12 days; age at autopsy 42 days) caused a significant decrease in the diameters of seminiferous tubules and Leydig cell nucleus and, cell counts of intermediate spermatogonia, round and elongated spermatids. Administration of FSH (75 micrograms/0.1 ml saline) + LH (25 micrograms/0.1 ml saline) everyday for 12 days to adrenalectomized mice restored testicular activity as revealed by significant increases in mean diameter of the Leydig cell nuclei and cell counts of intermediate spermatogonia and elongated spermatids over those of adrenalectomized mice. The results indicate that (i) testis of adrenalectomized mouse responds to gonadotropin treatment and (ii) impairment in gonadotropin secretion is possibly a major factor in inducing testicular regression following adrenalectomy.
