Final answer:
Testosterone is the hormone primarily responsible for the development of the male reproductive system, responsible for both the physical differentiation of male sexual organs and secondary sexual characteristics. Other hormones like estrogen and progesterone play more crucial roles in female reproductive health. Therefore , the correct answer options is c)
Step-by-step explanation:
The hormone that plays a key role in the development of the male reproductive system is testosterone. It is a steroid hormone produced primarily by Leydig cells in the testes. Testosterone is responsible for the anatomical differentiation of male sexual organs during embryonic development and the activation of secondary sexual characteristics such as muscle growth, facial hair, and voice deepening during puberty.
Along with follicle stimulating hormone (FSH), testosterone is also essential for spermatogenesis, which is the process of sperm production, and the functioning of the male reproductive organs like the prostate gland.
While other hormones like estrogen, progesterone, and epinephrine have important functions in the body, they are not primarily responsible for the development of the male reproductive system. Estrogen and progesterone are more closely associated with female reproductive health, whereas epinephrine is a hormone related to the body's 'fight or flight' response.
