28
Accessory glands of female reproductive
Mammary glands
29
What are ovaries attached to
Ovarian ligaments to uterus
30
Ovaries function
Site of folliculogenesis
31
Cortex of ovary
Ovarian follicles
32
Medulla of ovary
Large blood vessels, lymphatics and nerves
33
Site of fertilization
Fallopian tubes
34

36
What is the vagina the organ of
Copulation Delivery of baby
37

Perimetrium Myometrium Endometrium
38
Perimetrium uterus
Outer serous layer
39
Myometrium uterus
Middle layer of smooth muscle
40
Endometrium uterus
Inner musical lining Responds to hormones Shed menstruation Increases 5-6mm following menstruation due to progesterone
41
How many couples have infertility
1 in 8
42
43
GnRH triggers
FSH and LH
44
FSH stimulates
Releases androgen binding pro from sertoli Androgen binding pro makes spermatigenic cell receptive to testosterone
45
LH stimulates - male
Leydig to release testosterone
46
Testosterone acts - make
Locally to promote spermatogenesis Systemically to promote characteristics, libido, anabolic effect
47
Male infertility Pre testicular
Hypogonadotropin hypogonadism
48
Make infertility testicular
Poor sperm quality may result from trauma
49
Azoospermia
Absence of sperm in semen
50
Oligospermia
Few sperm in semen
51
Teratospermia
Abnormal morphology
52
Male infertility post testicular
Difficulty releasing sperm bc of structural abnormalities or failure of arousal Vas deferens obstruction and impotence
53
Follicular phase
GnRH derives FSH production and follicular growth
54
Pre ovulatory phase
Growing follicle produces estradiol Estradiol triggers LH surge Ovulation occurs
55
Literal
Corpus output produces progesterone
56
Proliferative phase
6-15
57
Secretory phase
Day 16-28
58
Menstrual phase
Day 1-5
59
Female infertility hypothalamus pituitary factors
Hypogonadotropic hypogonadism Damage to pituitary gland or hypothalamus Genetic defects Lactrogenic
60
