        The Male Reproductive System in Human

The male reproductive system consists of scrotum, which is suspended outside the abdominal cavity. This pouch keeps the testis temperature below the body temperature, which is necessary for the development of sperm. The tubules inside testis are about 250 meter long. The testis is connected to the vas deferens, which carries sperm to the prostate glands where it mixes with the seminal vesicles to form a viscous liquid/ so that it can easily flow out. This in turn is connected with the urethra then to the penis.

            Spermatogenesis

Sperm production begins at the age of puberty. It continues throughout the life, with several hundred million sperm being produced each day. Once sperm is formed/ it moves into the epididymis, where they mature and are stored.

             Male Sex Hormones

The pituitary gland produces follicle stimulating hormone (FSH) and luteinizing hormone (LH). It stimulates the cell, which secrete testosterone hormone that helps in productions of sperms.

        The male reproductive organ is testis. It lies in the pouch like structure called scrotum. The tube like structure which carries sperm from testis to outside is called:

(a) Ureter

(b) Vas deference

(c) Urethra

(d) Prostate gland

(e) None of these

Answer: (b)

Explanation

All are the parts of male reproductive system, but vas deference helps in carrying of sperm to outside.

         The hormones are the substance which regulates the functioning of our body. It also plays important role in our reproductive system. The hormones, which stimulates the formation of sperms in male is called:

(a) Progesterone

(b) Estrogen    

(c) Testosterone

(d) FSH

(e) None of these

Answer: (c)

Explanation

All of the options is hormones but option C is male reproductive hormones and the rest are female sex hormones.
