Which of the following statements accurately describes the role of the scrotum in the male reproductive system?
Which of the following statements accurately describes the role of the scrotum in the male reproductive system?
- It produces testosterone, which is essential for sperm maturation.
- It filters and removes waste products from the sperm as they develop.
- It serves as the primary storage site for mature sperm before ejaculation.
- It maintains the testes at a temperature slightly lower than normal body temperature, optimal for sperm production. (correct)
In human sexual reproduction, what proportion of the offspring's genetic material is contributed by each parent?
In human sexual reproduction, what proportion of the offspring's genetic material is contributed by each parent?
- $100\%$ from the father, $0\%$ from the mother
- $75\%$ from the father, $25\%$ from the mother
- $25\%$ from the father, $75\%$ from the mother
- $50\%$ from the father, $50\%$ from the mother (correct)
What is the primary function of the testes in the male reproductive system?
What is the primary function of the testes in the male reproductive system?
- To produce sperm and testosterone (correct)
- To protect sperm from the male's immune system
- To transport sperm from the epididymis to the urethra
- To store sperm until ejaculation

Study Notes
- Reproduction is how organisms create offspring.
- In humans, the organs and structures used for reproduction make up the reproductive system.
- Male and female reproductive systems differ, but both create gametes, which are reproductive cells that join to produce offspring.
- Humans reproduce through sexual reproduction, where both parents contribute genetic material, half from each parent.
Male Reproductive Organs and Structures
- The main components include: testes, scrotum, epididymis, sperm ducts, seminal vesicles, prostate gland, urethra, and penis.
- Males have a pair of testes, which produce sperm (male gametes/spermatozoa) and the male sex hormone testosterone.
- Testes reside outside the body in a sac of skin called the scrotum.
- The scrotum maintains optimal temperature for sperm production, slightly lower than normal body temp.
- Each testis contains coiled tubules where sperm are made; cells in the walls of these tubules undergo meiosis to produce sperm.
- Sperm produced in tubules are carried from the testes to the epididymis, a convoluted tube where sperm mature and are temporarily stored.
- Sperm ducts transport sperm from the epididymis and connect to the urethra below the urinary bladder.

Description
Overview of human reproductive systems, with a focus on the male anatomy. Primary components include the testes, scrotum, epididymis, sperm ducts, seminal vesicles, prostate gland, urethra, and penis. Sperm is produced in the testes, which reside in the scrotum.
