1. Why are the testes located in the scrotum rather than entirely inside the main body cavity?
To prevent testosterone from entering the bloodstream too quickly
To allow sperm to mix directly with prostate fluid

To separate urine from semen before ejaculation
2. A clinician describes the cervix as a passage between two structures. Which two structures are connected by it?
The uterus and the vagina
The bladder and the urethra
The uterus and an ovary
An ovary and a uterine tube
3. If both uterine tubes are completely blocked, which reproductive event is most directly disrupted?
Release of hormones from the pituitary gland
The meeting of sperm and egg
Shedding of the uterine lining
Production of eggs within the ovaries
4. What tissue is primarily shed during menstruation?
The muscular wall of the vagina
The endometrium
The lining of the uterine tube
The outer covering of the ovary
5. If luteinizing hormone does not adequately stimulate the testes, production of which hormone is most directly affected?
Testosterone
Insulin
Thyroxine
Melatonin
6. Which organ produces sperm cells?

Epididymis
7. What is a primary reproductive function of the prostate gland?
Adding fluid that contributes to semen

Carrying urine from the kidneys to the bladder
8. A fertilized egg normally implants in which tissue?

Inside an ovarian follicle
Inside the uterine tube
10. In a typical conception, where does fertilization most often occur?

11. After sperm mature in the epididymis, through which structure do they next travel during ejaculation?
Ureter
Seminal vesicle
Prostate gland

12. If both vas deferens are blocked, which outcome is most directly expected?
Urine can no longer leave the bladder
The testes immediately stop producing testosterone
The prostate can no longer produce fluid
Sperm are prevented from entering the semen
13. Which change most directly produces an erection?
Semen accumulates in the bladder
Erectile tissue fills with increased blood

It contains two complete sets of chromosomes
It contains one set of 23 chromosomes
It contains only sex chromosomes
15. Which sequence correctly traces the usual movement of an egg after it is released?
Ovary → uterine tube → uterus
Ovary → uterus → uterine tube → cervix
