The basic difference between spermatogenesis and oogenesis is that:

one mature ovum is produced in oogenesis, and four mature sperm are produced in spermatogenesis.

The organ that makes estrogen and progesterone is the:

ovary. The ovaries, which make estrogen and progesterone, are the primary sex organs of the female.

The reason the testes are suspended in the scrotum is:

to provide for a cooler temperature. Spermatogenesis requires a cooler temperature.

The sperm's acrosome:

contains enzymes. The acrosome contains enzymes, which allow the sperm to penetrate the egg.

The surge in LH that occurs during the middle of the ovarian cycle triggers:

ovulation. The surge in LH that occurs during the middle of the ovarian cycle triggers ovulation, which, on average, occurs on average at day 14 of the monthly cycle.

The uterine layer shed with each monthly cycle is the:

functional layer of endometrium. This innermost layer is shed when hormone levels drop at the end of the monthly cycle.

__________ cells, located between seminiferous tubules, produce testosterone.

Interstitial Interstitial, or Leydig, cells produce testosterone.

Which uterine phase does the functional layer of the endometrium start to rebuild?

Proliferative The functional layer of the endometrium starts to rebuild in the proliferative phase, which is initiated by rising estrogen levels.

What's the most common sexually transmitted disease in the U.S.?

Chlamydia Chlamydia, the most common sexually transmitted disease in the U.S., is an intracellular parasite.

Which is the most correct sequence of sperm flow in the male duct system?

Seminiferous tubules, epididymis, vas deferens, ampulla, ejaculatory duct, urethra

Which represents a correct cascade of reproductive hormones in males?

GnRH, LH/FSH, testosterone, inhibin

If the testes are both removed before puberty, will secondary sex characteristics develop in the male?

No, they won't develop and the man will be sterile.

Which of the following hormones causes the oocyte to mature?

FSH FSH stimulates the follicular cells and oocyte.

Ch.27 Reproduction System Questions

Question	Answer
Genetic variation is NOT enhanced through:	mitosis.
In response to parasympathetic stimulation:	blood flow increases to the penis. Parasympathetic stimulation causes NO to release, causes penile arterioles to dilate, allows the erectile bodies to fill w/blood.
The basic difference between spermatogenesis and oogenesis is that:	one mature ovum is produced in oogenesis, and four mature sperm are produced in spermatogenesis.
The organ that makes estrogen and progesterone is the:	ovary. The ovaries, which make estrogen and progesterone, are the primary sex organs of the female.
The primary sex organ of the male is the:	testes.
The reason the testes are suspended in the scrotum is:	to provide for a cooler temperature. Spermatogenesis requires a cooler temperature.
The sperm's acrosome:	contains enzymes. The acrosome contains enzymes, which allow the sperm to penetrate the egg.
The surge in LH that occurs during the middle of the ovarian cycle triggers:	ovulation. The surge in LH that occurs during the middle of the ovarian cycle triggers ovulation, which, on average, occurs on average at day 14 of the monthly cycle.
The usual site of fertilization is the:	uterine tube.
The uterine layer shed with each monthly cycle is the:	functional layer of endometrium. This innermost layer is shed when hormone levels drop at the end of the monthly cycle.
__________ cells, located between seminiferous tubules, produce testosterone.	Interstitial Interstitial, or Leydig, cells produce testosterone.
