- Large cysts - aching pelvic pain, dyspareunia
- abnml uterine bleeding with disturbance of ovulation
7
Q
tx for follicular cysts
A
- observation; symptomatic; resolve spontaneously < 2 mo
- OCPs - may not speed resolution of cysts
- Aspiration - done in past; not thought to help dx or reduce recurrence
- Cystectomy - for large or painful cysts

* Low day-21 progesterone level
* Anovulation on sonographic follicular monitoring
30
observation would be best for what type of PCOS pt?
maintenance?
* with regular cycle intervals (8-12/yr) and mild hyperandrogenism who do not desire to conceive
* Regular screening for lipids, DM, weight
31
lifestyle changes for PCOS
1. **5-10% wt loss** can restore normal ovulatory cycles in some patients
1. Reduces insulin and androgen levels
1. Well-balanced hypocaloric diet instead of low-carb/high-protein - Limited processed foods and foods with added sugars
1. Regular aerobic exercise
32
types of hormonal therapy for PCOS
1. COC
2. progesterone-only therapy
33
MOA of COC for PCOS
1. Induce regular menses and antagonizes endometrial proliferation
1. Reduce androgen lvl → suppress FSH/LH release, increase SHBG
- Chose COCs with progestins that have less androgenic properties
- Norethindrone, norgestimate, desogestrel, drospirenone
1. vaginal ring/patch - not well studied
2. If not pregnant - progesterone to cause withdrawal bleed before COC
34
for suspected PCOS, If pt has not had menses for > 4 weeks what must you obtain?
**pregnancy test**
35
1. Oral OR IUD
1. Mainly used in patients who cannot take COC
1. Helps prevent endometrial hyperplasia/cancer
- Some forms can be used for contraception
- Does not tx hyperandrogenic sx
Progesterone-only therapy
36
Insulin sensitizing agents for PCOS?

37
tx for NAFLD/NASH in PCOS?
* **Metformin** - can reduce risk, reduce progression
* Weight loss can also improve metabolic/hepatic function
38
tx for hirsutism
1. **_COCs_** - lower androgens, inc SHBG; **1st-line/initial tx**
1. **GnRH agonists** - lower androgen lvl; Expensive and undesirable SE of bone loss, menopausal s/s
1. **Depilation** - hair removal above skin surface; Shaving, topical chemical depilatories
1. **Epilation** - removal of entire hair shaft; Mechanical, electrolysis, laser

| 5-alpha-reductase inhibitors
43
tx for acne in PCOS
involves **lowering androgen levels**

* Topical treatments usually do not improve
45
2 Novel and Emerging Therapies for PCOS
1. **Myo-Inositol** - dietary supp; Second messenger - may help improve ***insulin sensitivity***
- maybe help ovulatory frequency, wt loss
2. **NK34 antagonists / Kappa-receptor agonists** - slows GnRH pulses
