Histology of the female reproductive system
ovaries
encapsulated by the tunica albuginea
covered by the germinal epithelium
simple cuboidal epithelium
PRIMORDIAL FOLLICLES
principle follicles present before birth
consists of
primary oocyte
enveloped by
single layer of flattened follicular cells.
PRIMARY FOLLICLES
zona pellucida
SECONDARY FOLLICLES
enlargement of the zona granulosa
follicular antrum
MATURE (GRAAFIAN) FOLLICLE
corona radiata
uterine tubes
musculomembranous tube
simple columnar epithelial layer
peg cells
ciliated cells
uterus
outer wall of the uterus

Physiology of Female Reproductive Tract
Menstrual cycle
Under hormonal control
Pre-ovulatory phase
Characterized with high estrogen levels
Follicular phase in ovaries
Follicle development and release of oocyte
Proliferative phase in uterus
Endometrium thickening
Emergence of spiral arteries
Thin watery cervical mucus
More hospitable for sperms
Ovulation
In day 14 of the cycle
Due to Estorgen induced LH surge
Rupture of graafian follicle
Expulsion of the ovum
Entrance of ovum to fallopian tube
Post-ovulatory phase
Characterized with high progesterone levels
Luteal phase in ovaries
Formation of corpus luteum
Production of progesterone/ estrogen and inhibin
Degenerates to corpus albicans if there was no fertilization
Secretory phase in uterus
Spiral arteries grow longer
Uterine glands secrete more mucus
Thick cervical mucus
Less hospitable for sperms
Functional layer of endometrium sloughs off if there was no fertilization
Menstruation
Fertilization
In ampulla
3 Phases
Penetration of corona radiata
After capacitation of sperms
Penetration of zona pellucida
Acrosome reaction
Fusion of oocyte and sperm cell membrane
Cortical and zona reaction
Noora
PCOS
Caused by elevation of LH
Overstimulate theca cell
Produce androstenedione
Increase LH To FSH ratio
Insulin resistance
Hyperinsulinemia via inc androgenic enzymes and dec in SHBG
Clinical features
Hirsutism
Acne
Male pattern alopecia
Menstrual abnormalities
Weight gain 60%
Acanthus is nigricans
Risk factor
Genetic-Obesity - sedentary lifestyle - intrauterine androgen exposure
Morphology
Both ovaries will be enlarged with multiple subcortical cysts
