D
ovaries and testes
Explanation: 

Detailed explanation-1: -LH has various functions, which differ between women and men. In both sexes, LH contributes to the maturation of primordial germ cells. In men, LH causes the Leydig cells of the testes to produce testosterone. In women, LH triggers the creation of steroid hormones from the ovaries [1].

Detailed explanation-2: -Follicle stimulating hormone is produced by the pituitary gland. It regulates the functions of both the ovaries and testes.

Detailed explanation-3: -Theca cells are regulated by LH and these cells undergo a “luteinization” phase like the granulosa cells, where they become “theca-lutein” cells that directly produce progesterone as part of the Corpus Luteum.

Detailed explanation-4: -Follicle-stimulating hormone (FSH): This hormone stimulates the testes to produce sperm and stimulates the ovaries to produce eggs and estrogen. Luteinizing hormone (LH): This hormone stimulates ovulation in women and testosterone production in men.
