Summary Introduction

To match: Each structure with its description


Testis – d. produces testosterone.

The testis is the primary male reproductive organ that produces the sperms. The testis projects out of the pelvic girdle and is present inside the scrotum. The testis has Leydig’s cells that produce testosterone, when induced by hormones from the pituitary.

Epididymis – c. stores sperms.

The testis produces the sperms in its seminiferous tubules. The sperms from the seminiferous tubules are collected and stored in the epididymis. From the epididymis, the sperms are sent to the vas deferens.

Labia majora – h. fat-padded skin folds.
