Reproductive pathologies Flashcards
What is menopause?
cessation of menses for 12 consecutive months
What is the physiology of menopause?
- •As ovarian follicles diminish with age, so too does the amount of oestrogen produced by granulosa cells
- •BecauseLH secretion isdependent on oestrogen levels, menopause is preceded by ~5 years of increasingly anovulatory cycles (referred to as the climacteric)
- •Eventually, menstruation ceases due to reduced number of follicles & reduced responsiveness to FSH
- •Average age for cessation of menses: 51 years
What are the clinical features of menopause?
Non-specific - hot flushes, hight sweat, fatigue, lethargy
reproductive: reduction fo breast size, vaginal dyspareunia, UTI
Neurological: changes mood and memory, headache, dizziness
Musculoskeletal: osteoporosis, arthralgia, myalgia
cardiovascular: HBP, AMI
what is the climacteric period?
period with irregular menses before complete cessation of menstruation
What are the advantages and disadvantages of hormone therapy?
ADVANTAGES
- •Relieves symptoms of menopause
- •Prevents early menopausal bone loss – reductionin #risk
DISADVANTAGES
- •‘Premenstrual-like’ symptoms e.g. bloating & fluid retention, breast tenderness, irritability
- •Increased risk for:
- •Thromboembolic disease
- •Cardiovascular disease: stroke
- •Cancer: breast, endometrial (oestrogen-only HT)
- •Gall bladder disease
What is Polycystic ovarian syndrome?
Inappropriate secretion of gonadotrophins
Diagnostic criteria
- menstrual irregularity
- clinical hyperandrogenism
- polycystic ovaries
What is the correlation between PCOS and Chronic disease?
Hyperinsulanemia
What is the pathophys behind PCOS?
- •Follicular growth is continuously stimulated, but not to full maturation
- •Hyperinsulinaemia suppresses normal follicular apoptosis – this permits the survival of follicles that would normally disintegrate
- •The net result is anovulation and enlargement of the ovaries with cyst formation
What are the clinical features of PCOS?
- •Menstrual disturbance: oligomenorrhoea, amenorrhoea
- •Infertility
- •Hyperandrogenism: acne, hirsutism, male pattern baldness
- •Obesity (38% of cases)
- •Asymptomatic (20% of cases)
- •Increased risk for: Type 2 diabetes, cardiovascular disease, endometrial cancer
