Study Notes

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

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

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: 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

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
