Question: Rekha told her friend Babita that even after four years of marriage she is not able to bear a child ...

Rekha told her friend Babita that even after four years of marriage she is not able to bear a child and sarcastic remarks of her in- laws make her depressed. Rekha told Babita that she and her husband should get examined by a doctor. After examination, the doctor found no abnormalities in Rekha and his husband except low sperm count of her husband. Rekha told her friend that her husband takes alcohol, drugs and smoke daily. Her husband has some defects in the erection of the penis.
What is the use of erection of the penis?

Explanation

Solution

Erection is the enlarged and rigid state of the penis, typically in sexual excitement.When men become sexually aroused, hormones, muscles, nerves, and blood vessels all work with each other to make an erection. Nerve signals, sent from the brain to the penis, stimulate the muscles to relax. This, in turn, allows blood to flow to the tissue within the penis.

Complete Step by Step Answer:
If a man is unable to erect his penis properly, he is unable to perform intercourse and semen containing sperms cannot be introduced into the vagina in the required amount.
The anatomy of the penis:
The penis is formed up of:
- Two chambers called the corpora cavernosa, which run the length of the organ and contain many types of blood vessels shaped like cavernous spaces (like a sponge).
- The urethra, or channel for urine and sperm, which runs along with that of the underside of the corpora cavernosa.
- Erectile tissue, which surrounds the urethra, two main arteries and a number of other veins and nerves.
- The shaft, the longest part of the penis.
- The head (glans), which is at the top of the shaft.
- The meatus, or opening at the tip of the head is where urine and semen are discharged.

Note: Don't get confused by these two words- Erection and ejaculation. Erection is the enlarged and rigid state of the penis, typically in sexual excitement, while ejaculation is when a male is sexually aroused, and tubes called the vas deferens squeeze sperm from the testes toward the back of the urethra, the tube via which the semen flows through as the seminal vesicles also release fluid there.
