Learning Objectives

• Compare major similarities and differences between male and female gametogenesis
• Relate major histological features of the ovary to the stages of follicle development
• Identify the major phases of the female reproductive cycle and the major events occurring within those phases including: (i) ovarian events of folliculogenesis, ovulation & CL formation, (ii) endometrial events of proliferation, secretory changes and menstruation
• Explain the role of the hypothalamic-pituitary-ovarian axis in the endocrine regulation of the ovarian and uterine cycles
• Recognise the differences in control of the corpus luteum during the pregnant and non-pregnant cycle

Menstrual Cycle

• how long does a single cycle take?

Oogenesis

• compare gametogenesis in males vs females?
• oocytes are kept in meiotic arrest, how long can this last for?
• what are the steps of oogenesis?
• what are the preantral and antral follicle types?
• how long does it take for a primordial follicle to progress to a primary follicle?
• how is the menstrual cycle only 28 days then?

Ovarian Cycle & Folliculogenesis

• why does follicular atresia begin halfway through gestation?
• what are the 2 phases of the ovarian cycle?
