What hormone is primarily responsible for stimulating the growth of ovarian follicles?

What role does luteinizing hormone (LH) play in the menstrual cycle?

True or False: Sperm can survive for several days in a female’s reproductive tract.
True.
What is the duration of a typical menstrual cycle?
Approximately 28 days.
Which hormone surge triggers ovulation?
Luteinizing hormone (LH).
What is the primary purpose of gametogenesis?
To produce haploid gametes for sexual reproduction.
What structure in the male anatomy is responsible for the production of testosterone?
The Leydig cells in the testes.
Fill in the blank: The _______ is the external part of the female genitalia.
vulva.
What is the role of FSH in males?
FSH stimulates sperm production in the testes.
True or False: The luteal phase occurs before ovulation.
False: The luteal phase occurs after ovulation.
What is the function of the corpus luteum?
The corpus luteum secretes progesterone after ovulation.
What happens during the menstrual phase of the menstrual cycle?
The uterine lining sheds if no fertilization occurs.
