Male produces _____ of sperm daily
Sperm are stored and mature in
If sperm aren't expelled from the body within a certain period, they are ____
_____ produce large amounts of sex hormones which affect maturation, development, and changes in the activity of the reproductive system organs.
Sex hormones in females
estrogen and progesterone
Sex hormones in males

Both males and females have accessory reproductive organs including ______ to carry gametes away from the gonads toward the site of fertilization
Epididymis, Ductus (vas) deferens, Ejaculatory duct, and Urethra make up the ______
The seminal vesicles, prostate, and bulbourethral glands make up the
3 accessory glands
_______ are the primary gonads that produce and synthesize sperm and hormones
is a fibromuscular cutaneous sac, located between the penis and anus.
the site of sperm & testosterone production.
functions as a storage reservoir for sperm & site of sperm maturation.
a collection of muscle fibers, vessels, nerves and ducts that run to and from the testes.
What are the 3 paired structures of the scrotum?
testis, epididymis, and the spermatic cord
What are the muscle fibers within scrotum?
dartos and cremaster
_____ muscle is a sheet of smooth muscle, situated immediately underneath the skin. It acts to help regulate the temperature of the scrotum, by wrinkling the skin –this decreases surface area, reducing heat loss
Originally, the testes are located on the ________
posterior abdominal wall
T/F: As the testes descend through the inguinal canal to the scrotum, they carry their neurovascular supply with them
During embryonic development they descend down the abdomen, and through the _______ to reach the scrotum.
Arterial supply to the testes and epididymis is via the paired _____ arteries
Lymphatic drainage to the testes is to the ________ nodes
lumbar lymph and preaortic nodes
Network of nerves derived from the renal and aortic plexi that innervate the testis
The ______ is a network of veins, responsible for the venous drainage of the testes, acts as a heat exchanger, cooling the arterial blood before it reaches the testes.
As it travels through the inguinal canal, the pampiniform plexus condenses into a
single testicular vein
