Male Reproductive System (Sherpath)

Which describes the function of the cremaster muscle in the male reproductive system?

Controls temperature of the testes The function of the cremaster muscle in the male reproductive system is to control the temperature of the testes by relaxing or tightening to keep sperm within the testes cooler than the core body temperature.

Which internal structure of the male reproductive system ensures sperm survive during intercourse?

Prostate gland The prostate gland is an internal structure of the male reproductive system that ensures sperm survive during intercourse by secreting seminal fluid that protects the sperm from the acidic environment of the vagina.

Which statement accurately describes a function of testosterone in male sexual maturation?

Release of testosterone causes increased growth of bones. One function of testosterone in male sexual maturation is to cause increased growth of the skeletal system

How do structures of the male reproductive system enhance motility of sperm?Select all that apply.

Seminal vesicles produce an alkaline fluid. The seminal vesicles secrete an alkaline seminal fluid that enhances both the motility of the sperm and the ability to survive in the acidic environment of the vagina. The prostate gland secretes seminal fluid. The prostate gland secretes seminal fluid that enhances motility of the sperm. The bulbourethral glands add fluid to semen. The bulbourethral glands secrete seminal fluid that enhances motility of the sperm.

Which processes explain the development of the deepened voice and increased muscle mass during male sexual maturation?Select all that apply.

Testosterone targets adrenal glands. Testosterone targets adrenal glands, causing development of secondary sex characteristics. Luteinizing hormone (LH) causes the testes to secrete testosterone. LH causes the testes to secrete testosterone, which results in development of secondary sex characteristics, including a deepened voice and increased muscle mass.

Which statement explains the function of the hypothalamus in male sexual maturation?

The hypothalamus releases gonadotropin-releasing hormone (GnRH), leading to enlarged testes. The function of the hypothalamus is to release GnRH to initiate puberty and cause male sexual maturation.
