Female Reproductive System: Hormones & Menstrual Cycle Quiz

Here are the study notes for the Female Reproductive System (Hormones & Menstrual Cycle):

Hormones

• Estrogen: primary sex hormone responsible for female reproductive characteristics and sexual development
• Progesterone: hormone that prepares the uterus for implantation of a fertilized egg
• Follicle-stimulating hormone (FSH): stimulates follicle growth in the ovaries
• Luteinizing hormone (LH): triggers ovulation and corpus luteum formation
• Oxytocin: stimulates uterine contractions during childbirth and milk letdown during lactation

Menstrual Cycle

• Average duration: 28 days, but can range from 21 to 35 days
• Phases: menstrual, follicular, ovulatory, and luteal
• Menstrual phase: days 1-5, shedding of uterine lining, and preparation for a new cycle
• Follicular phase: days 1-14, growth and maturation of ovarian follicles, and increased estrogen levels
• Ovulatory phase: days 14-17, LH surge triggers ovulation, and release of a mature egg
• Luteal phase: days 17-28, corpus luteum formation, and increased progesterone levels

Ovulation and Fertilization

• Ovulation: release of a mature egg from the ovary, usually around day 14 of a 28-day cycle
• Fertilization: fusion of a sperm and an egg, resulting in a zygote
• Fertilization usually occurs in the fallopian tube

Hormonal Regulation

• Hypothalamic-pituitary-ovarian (HPO) axis: complex feedback loop that regulates hormone production and the menstrual cycle
• Negative feedback loop: high estrogen and progesterone levels inhibit FSH and LH production
• Positive feedback loop: low estrogen and progesterone levels stimulate FSH and LH production
