Normal length of menstrual cycle
28 days
Phases of menstrual cycle
Follicular phase - follicles grow
Ovulation (1 day)
Luteal phase
Follicular phase hormone
FSH - causes growth of follicles
GnRH causes FSH release from anterior pituitary
Inhibin is later released to inhibit FSH
Name of follicle that ovulates (releases oocyte)
Mature/Grafian follicle
Hormone that causes ovulation
LH
Day 14 of 28 day cycle
Causes oocyte release
Corpus luteum
What the follicle turns into after ovulation
Produces oestrodiol and progesterone
Lasts for 2 weeks producing hormones unless egg is fertilised (stays for about 3 months until placenta takes over)
Degenerates into corpus albicans (doesn’t produce hormones)
Follicular phases
Primordial follicles Primary follicles Secondary follicles Tertiary follicles (most grown one is released into Fallopian tube) Corpus luteum Involution Corpus albicans Primordial follicles
HCG secreted by fertilised egg
Prevents corpus luteum undergoing involution
Uterine cycle phases
Menstrual phase Proliferation phase (grows) Secretory phase (continues growing + good vasculature, secretes more endometrium) If no fertilisation, endometrium breaks down
What happens during menstruated phase
Follicles grow
Menstration
Layer of endometrium always present
Stratum basalis
Layer of endometrium that breaks off
Stratum functionalis / functional layer
Layer below endometrium
Myometrium
Name of fertilised egg that starts mitosis
Blastocyst
Day fertilised egg will implant in uterine lining
About day 21
When uterine lining is at its thickest
Hormone responsible for blood vessels and increased secretion of stratum functionalis
Progesterone (+ oestradiol) secreted from corpus luteum
Time after which corpus luteum involutes if no blastocyst implantation
About 2 weeks
Reduces progestone levels
Menarche
The first menstrual cycle
Menopause
The cessation of menstruation for 12 consecutive months (not on hormonal contraception)
Diagnosed based on age + symptoms
Dysmenorrhoea
Painful menstruation
Menorrhagia
Abnormally heavy bleeding at menstruation
Metrorhagia
Period lasts for more than 7 days or spotting between periods
Not used very often
Oligomenorrhoea
Infrequent menstrual periods (less than 6-8 peer year)
Primary amenorrhea
Absence of menses at age 15 years in the presence of secondary sexual characteristics and normal growth
