Male Reproductive System
This structure produces sperm and testosterone.
What are the testes?
This structure releases eggs during ovulation.
What is the ovary?
This hormone triggers ovulation.
What is luteinizing hormone (LH)?
Fertilization occurs when these two cells join.
What are sperm and egg cells?
If fertilization does not occur, this structure sheds its lining.
What is the uterus?
This structure is where sperm mature and gain motility.
What is the epididymis?
This structure is the site of fertilization.
What is the fallopian tube?
This hormone helps rebuild the uterine lining during the follicular phase.
What is estrogen?
This process occurs when a fertilized egg attaches to the uterine lining.
What is implantation?
What happens if ovulation does not occur?
What is fertilization cannot occur because no egg is released?
List the correct pathway sperm travel after leaving the testes.
What is epididymis → vas deferens → urethra?
This structure supports implantation and development of the embryo.
What is the uterus?
What happens during ovulation?
What is the release of an egg from the ovary?
Why is timing important in reproduction?
What is egg release, sperm availability, and uterine readiness must occur at the same time?
A decrease in estrogen and progesterone causes this event.
What is menstruation?
A patient produces healthy sperm, but sperm cannot leave the body. Which structure is most likely blocked?
What is the vas deferens?
A fertilized egg forms successfully, but implantation does not occur. Which structure is most likely not functioning properly?
What is the endometrium?
A patient does not experience an LH surge. What process will most likely fail?
What is ovulation?
A fertilized egg forms, but it never implants. Will pregnancy continue successfully? Explain why or why not.
What is no because the embryo must implant into the uterine lining to receive nutrients and continue development?
A patient ovulates normally and sperm are healthy, but fertilization never occurs.
Explain which structure is most likely malfunctioning AND why fertilization fails.
What is the fallopian tube because the egg and sperm cannot meet if the egg cannot travel through the tube?
A patient has normal testosterone levels but is infertile because sperm cannot mature properly. Explain which structure is malfunctioning and why fertility is affected.
What is the epididymis because sperm must mature and gain motility before fertilization can occur?
A blockage occurs in the fallopian tube. Explain how this affects fertilization and what happens to the egg after ovulation.
What is fertilization will not occur because the egg cannot travel through the tube to meet sperm?
Progesterone levels do not rise after ovulation. Explain how this affects the uterine lining and possible pregnancy.
What is the uterine lining will not be maintained, making implantation and pregnancy unlikely?
Explain how the ovary, fallopian tube, and uterus work together to support reproduction.
What is the ovary releases the egg, the fallopian tube transports the egg and is the site of fertilization, and the uterus supports implantation and development?
A patient ovulates normally and fertilization occurs, but progesterone levels suddenly decrease. Predict what will most likely happen next and explain why.
The uterine lining would not be maintained, making implantation or continued pregnancy unlikely because progesterone supports the uterine lining after fertilization?
