Question

Quizplus · Accepted Answer

The moment of orgasm is characterized by rhythmic contractions of many parts of the reproductive system, including the uterus, fallopian tubes, and pelvic muscles in females, and the prostate gland, seminal vesicles, and urethra in males.

Answer: A and D are incorrect; B and E are partially incorrect.

A) The moment of orgasm is not characterized by ovulation of the oocyte from the ovary, which typically occurs before or after orgasm.
B) The release of sperm from the seminiferous tubules is not the defining feature of orgasm in males. Men may experience orgasm without ejaculation and vice versa.
C) Rhythmic contractions of many parts of the reproductive system are the hallmark of orgasm, as explained above.
D) Increased synthesis and release of ovarian steroid hormones do not occur at the moment of orgasm; instead, the hormonal changes associated with orgasm are primarily related to the release of oxytocin and endorphins.
E) Increased synthesis and release of testicular steroid hormones may occur during sexual arousal and preceding orgasm but are not a defining feature of the moment of orgasm itself.
