FSH and LH get their names from their role in female reproductive cycle, but they also function in males.
(a) What are their functions in male?
(b) How are their functions in females and males similar?

Explanation

(a) In males, FSH stimulates Sertoli cells which nourish developing sperm. LH stimulates production of androgens (mainly testosterone) which in turn stimulates spermatogenesis.
(b) In both males and females, FSH encourages growth of cells that support and nourish developing gametes (Sertoli cells in males and follicle cells in females) and LH stimulates sex hormone production (testosterone in males and estrogen in females) which promote gametogenesis.
