Ans: B, C, D
Feedback:
Male sex hormone levels, particularly testosterone, decrease with age. The sex hormones play a part in the structure and function of the reproductive system and other body systems from conception to old age; they affect protein synthesis, salt and water balance, bone growth, and cardiovascular function. Decreasing levels of testosterone affect sexual energy, muscle strength, and the genital tissues. The testes become smaller and lose their firmness. The prostate gland enlarges, and its contractions become weaker. The force of ejaculation also decreases because of a reduction in the volume and viscosity of the seminal fluid.
