Q

What happens to the scrotal muscle when the weather is cold or hot?

A

(A) In cold weather, the scrotal muscle contracts and brings the testes closer to the body.
(B) In very hot weather, the scrotal muscle relaxes allowing the testes to fall away from the body.

Because of the scrotum’s function, the temperature of the testes can remain as even as possible to promote the production and viability of the sperm.

Q

When does the testes descend among male fetuses?

A

Testes in a fetus form in the pelvic cavity and then descend late in intrauterine life (about 34th to 38th week of pregnancy) into the scrotal sac. Because this descend occurs late in pregnancy, many male infants born preterm will have undescended testes.

(descent does not occur in the extrauterine life)

Q

How do spermatozoa mature?

A

(A) The hypothalamus releases GnRH, which in turn influences the anterior pituitary gland to secrete FSH and LH.
(B) Androgen binding protein and testosterone then combine to form sperm formation.
(C) when the production of testosterone reaches peak amount, a feedback effect on the hypothalamus and APG is created, which slows down the production of FSH and LH, which then decreases and regulates sperm production.

Q

Characterize the testes.

A

One testis is slightly larger than the other and is suspended slightly lower than the scrotum than the other (usually the left one). Because of this, testes tend to slide past each other more readily on sitting or muscular activity, and there is less possibility of trauma to them.

It normally feels firm, smooth and are egg shaped.

Q

True or false. Spermatozoa can survive at a temperature as high as that of the internal body?

A

Q

What are the recommendations of the American Academy of Pediatrics (AAP) on circumcision?

A

The AAP advises that circumcision decisions should be made in consultation with parents with consideration of their cultural or religious beliefs. Its advantages allow for lower rates of urinary tract infections, HIV, STIs, and penile cancer. Its disadvantages include surgical complications, such as bleeding and pain, and reduction of sensation with sexual stimulation.

What is the role of Bartholin glands?

A

To secrete fluids that lubricate the external genitalia during coitus and improve sperm survival.

(If the Skene glands or the Bartholin glands (the most common site) become infected, they swell, feel tender, and produce a serous discharge)
