Male sexual reproductive organ

The penis is made up of two main areas; the shaft, which is made of spongy tissue that fills with blood when the penis is erect, and the glans, the sensitive tip which is covered by foreskin in uncircumcised men. It takes sperm about 4 to 6 weeks to travel through the epididymis. A deep fascia, or sheet of connective tissue , surrounding the structures in the body of the penis is prolonged to form the suspensory ligament, which anchors the penis to the pelvic bones at the midpoint of the pubic arch. The seminal vesicles have longitudinal and circular layers of smooth muscle, and their cavities are lined with mucous membrane, which is the source of the secretions of the organs. Their secretions form the bulk of semen. The vas deferens empties into the ejaculatory duct, which passes through the prostate gland to merge with the urethra.

The inside of the penis is made of a spongy tissue that can expand and contract. It is not a substitute for medical advice, diagnosis or treatment. The penis, which usually hangs limp, becomes hard when a male is sexually excited. The vagina, a muscular tube extending from the uterus to the outside of the body, is the receptacle for sperm ejaculated during sexual intercourse and also forms part of the birth canal that will be used later, when the offspring comes to term.
