• Progesterone
• Estrogen

Do the levels of FSH and progesterone increase or remain low during the first 5 days of the menstrual cycle?

• Progesterone remains low but FSH increases
• Progesterone and FSH both remain low
• Progesterone increases but FSH remains low
• Progesterone and FSH both increase

Which correctly describes the role of the epididymis in semen production?

• Produces fluid containing fructose to nourish sperm
• Finishes maturation of sperm so they are capable of swimming
• Produces alkaline fluid with minerals to protect sperm

How is in vitro fertilization different from natural fertilization in humans?

• In vitro involves artificial injection of sperm into the uterus
• In vitro only involves one parent
• In vitro happens outside the body
• In vitro uses stem cells instead of eggs

Which of the following is a role of LH?

• Stimulates ovulation
• Stimulates repair and maintenance of endometrial lining
• Stimulates follicle development
• Inhibits FSH

Which of the following demonstrates positive feedback during the menstrual cycle?

• High levels of estrogen produce more FSH receptors on follicle cells which allows them to produce more estrogen
• High levels of estrogen eventually inhibit FSH
• High levels of progesterone inhibit FSH and LH
• High levels of LH inhibit estrogen

Which of the following demonstrates negative feedback during the menstrual cycle?

• High levels of estrogen produce more FSH receptors on follicle cells which allows them to produce more estrogen
• High levels of estrogen eventually inhibit FSH
• High levels of oxytocin cause contractions which lead to the release of more oxytocin
• High levels of progesterone lead to menstruation

Which hormone stimulates repair of the endometrial lining

• Estrogen
• Progesterone
• LH
• FSH

Which hormone causes the primary follicle to develop?

• FSH
• LH
• Estrogen
• Progesterone
