The male reproductive organ are following:-

 A. External genital organs

 1. Peins

 • Erectable and highly muscular organ, used for copulation

 • Hanging over the scrotum , become erect due to filling of Blood to spongy erectile tissue.

 • Terminal part of peins is called glans penis.

 2. Scrotum

 • It is hanging out side of abdomenl cavity

 • Scrotal sac is filled with a fluid called hydrocele.

 • The scrotal sac communicate with the abdomenl cavity by a narrow canal callled inguinal canal

 B. Internal genital organs

 1. Testis

 • It is primary sex organs, a paired , oval bodies.

 • Each testis is divided into 200-300 testicular lobules by septa. Each lobules contains 1-4 seminiferous tubules.

 2. Epididymis

 • Very thin, very large, and highly convoluted mass of tube, lies outside and partlly encircling the tesits.

 • Divided into three parts- caput epididymis , corpus epididymis and cauda epididymis.

 3. Ductus deferens or vas deferens

 • Thick walled muscular tube emerges from Cadua epididymis and enter into abdomenl cavity through inguinal canal.

 • Forms a loop around urinary bladder, and then joins ducts from seminal vesicles to form ejaculatory duct.

 4. Spermatic cord

 • Testis is held inside the scrotal sac by thick fibrous tissue called spermatic cord.

 5. Seminal vesicles

 • A pair, fibro muscular pouch below urinary bladder.

 • Secrets alkaline viscous fluid that provides nutrient to spermatozoa.

 6. Ejaculatory duct

 • A pair, formed by union of ducts from seminal vesicles and vas deferens.

 7. Male urethra

 • Tube arises from urinary bladder

 • Common tube for discharge of urine and semen.

 8. Prostate gland

 • One in number, below urinary bladder and between two seminal vesicles.

 • Discharge its secretion to urethra, helps in sperm mobility and nourishment of sperms.

 9. Bulbo urethral glands or cowper's glands

 • A pair, pea sized, situated below prostate gland and at the base of penis.

 • Secret alkaline fluid, serves as lubricant for vagina.
