Accepted Answer

Swallowing seminal fluid is generally considered safe for most people, provided the male does not have a sexually transmitted infection (STI) that could be transmitted through the fluid.

Question 6

Retrograde ejaculation may potentially be harmful because of the buildup of seminal fluid in the bladder.

Question 12

Kegel exercises, similar to those done by women, have little use for men.

Accepted Answer

Question 13

The penis is primarily composed of bone and muscle tissue.

Accepted Answer

The penis is primarily composed of spongy tissue, including the corpora cavernosa and the corpus spongiosum, not bone and muscle tissue.

Question 14

The practice of circumcision involves removal of the penis and the testicles.

Accepted Answer

Circumcision involves the removal of the foreskin from the penis, not the penis or the testicles.

Question 15

The major portion of seminal fluid is produced in the prostate gland.

Accepted Answer

The major portion of seminal fluid is actually produced by the seminal vesicles, not the prostate gland. The seminal vesicles contribute about 60-70% of the ejaculate volume, whereas the prostate contributes around 20-30%.

Question 16

Cold temperatures may trigger the cremasteric reflex.

Accepted Answer

The cremasteric reflex is a response where the testicles are pulled closer to the body in response to cold temperatures, among other stimuli, to regulate the temperature of the testes for optimal sperm production.

Question 17

Accepted Answer

Circumcision is associated with several health benefits, including a reduced risk of urinary tract infections, a lower risk of sexually transmitted infections (including HIV), and a reduced risk of penile cancer.

Question 20

The testicles not only produce sperm but also secrete male sex hormones.

Accepted Answer
