True
What is the function of the vas deferens?

B) Testosterone
What is the process of sperm production called?
Spermatogenesis
Fill in the blank: Sperm are stored in the ______ until ejaculation.
epididymis
True or False: The urethra serves both urinary and reproductive functions in males.
True
What is the primary function of the male reproductive system?
To produce and deliver sperm
What is the role of testosterone in the male body?
Regulating libido, muscle mass, and bone density
What is the term for the fluid that carries sperm during ejaculation?
Seminal fluid or semen
What is the function of the testes in terms of hormone production?
To produce testosterone
Fill in the blank: The ______ is the tube that carries sperm from the epididymis to the urethra.
vas deferens
Multiple choice: Which part of the sperm contains the genetic material? A) Midpiece B) Tail C) Head D) Acrosome
C) Head
What is the primary difference between primary and secondary male reproductive organs?
Primary organs produce gametes; secondary organs support and transport them.
Multiple choice: Which of the following is a secondary sexual characteristic in males? A) Breast development B) Body hair C) Menstruation D) Ovarian function
B) Body hair
What is the primary function of the vascular system in the testes?
The primary function is to supply oxygen and nutrients to the testicular tissues and to remove waste products.
True or False: The vascular system of the testes plays a role in thermoregulation.
True
Fill in the blank: The primary risk factor for testicular cancer is a history of __________.
cryptorchidism
Fill in the blank: The primary risk factor for testicular cancer is a history of __________.
cryptorchidism
What are seminiferous tubules?
Coiled structures in testies where sperm production occurs
What cells are responsible for producing testosterone in the testies?
Leydig cells
What’s the process of the sperm production called?
Spermatogenisis
In what part of the male reproductive system does the sperm mature?
The epididymis
What is the primary function of sperm?
To fertilize the ovum (egg) for reproduction.
Fill in the blank: The tail of the sperm is also known as the __________.
flagellum
What structure in sperm contains enzymes crucial for fertilization?
The acrosome
Multiple Choice: Which part of the sperm is responsible for its motility? A) Head B) Midpiece C) Tail D) Acrosome
C) Tail
What is the role of the midpiece in sperm anatomy?
It contains mitochondria that provide energy for movement.
What is the shape of a typical sperm cell?
It has a head, midpiece, and a long tail.
Multiple Choice: Which component of sperm carries the genetic material? A) Tail B) Midpiece C) Head D) Acrosome
C) Head
Describe the function of the acrosome in sperm.
The acrosome releases enzymes that help the sperm penetrate the outer layers of the egg.
What is the primary function of mitochondria in sperm cells?
To produce ATP for energy necessary for motility.
True or False: Mitochondria are only found in the midpiece of sperm cells.
True.
What is the role of the vascular system in sperm cell function?
To supply oxygen and nutrients and remove waste.
What is produced by mitochondria during cellular respiration?
ATP
Fill in the blank: The vascular system plays a crucial role in ______ of sperm cells.
thermoregulation.
What is the effect of hypoxia on sperm function?
It can impair sperm motility and viability.
Fill in the blank: The vascular system helps maintain the ______ environment necessary for sperm production.
homeostatic.
