1. High-Yield Flashcards
Tap each question to reveal the answer.
What is infertility?
Failure to achieve pregnancy after about 12 months of regular unprotected intercourse.
What is the main cause of infertility in PCOS?
Chronic or recurrent anovulation due to failure of normal follicular maturation.
How does hyperinsulinemia worsen hyperandrogenism in PCOS?
It increases ovarian androgen production and reduces hepatic sex hormone-binding globulin production.
What ovarian morphology supports PCOS?
Multiple arrested follicles, increased stromal tissue, and theca interna hyperplasia/luteinization.
What is the classic gross appearance of a uterine leiomyoma?
A sharply circumscribed, firm, white-gray mass with a whorled cut surface.
Which fibroid location is most associated with heavy bleeding and impaired implantation?
Submucosal fibroid because it distorts the endometrial cavity.
What is the most common degenerative change in a leiomyoma?
Hyaline degeneration.
What is endometriosis?
Presence of functional endometrial glands and stroma outside the normal endometrial cavity.
Why does endometriosis cause infertility?
Repeated hemorrhage causes inflammation, fibrosis and adhesions that distort tubo-ovarian anatomy.
What histological finding strongly supports chronic endometritis?
Plasma cells within the endometrial stroma.
What is the main action of FSH in fertility treatment?
Stimulation of granulosa cells and follicular development.
Why is hCG used after adequate follicular development?
It activates LH receptors and triggers final follicular maturation and ovulation.
What happens with continuous GnRH agonist administration?
Initial stimulation is followed by GnRH-receptor down-regulation and suppression of FSH and LH.
How does clomiphene induce ovulation?
It reduces estrogen negative feedback at the hypothalamus, increasing GnRH, FSH and LH secretion.
Which adverse effects are characteristic of danazol?
Androgenic effects such as acne, hirsutism, weight gain and voice deepening.
How are stress and urge urinary incontinence clinically distinguished?
Stress leakage follows coughing or exertion; urge leakage follows sudden compelling urgency.

3. Memory Tables
Stress vs Urge vs Overflow Incontinence
| Feature | Stress | Urge | Overflow |
|---|---|---|---|
| Typical clue | Cough / sneeze leakage | Urgency before leakage | Dribbling + incomplete emptying |
| Mechanism | Poor urethral support | Detrusor overactivity | Chronic retention |
| Key management | Pelvic-floor training | Bladder training ± medication | Correct retention/cause |
Fibroid vs Endometriosis
| Feature | Leiomyoma | Endometriosis |
|---|---|---|
| Core lesion | Benign smooth-muscle tumor | Ectopic endometrial glands/stroma |
| Hallmark morphology | Whorled white-gray mass | Hemorrhagic implants / chocolate cyst |
| Major fertility effect | Cavity distortion | Inflammation + adhesions |
| Typical symptom | Heavy menstrual bleeding | Dysmenorrhea / pelvic pain |
4. Rapid Revision Points — Last-Minute Revision
- PCOS links insulin resistance and androgen excess with follicular arrest and anovulation.
- Persistent anovulation increases the risk of endometrial hyperplasia through inadequate progesterone opposition.
- Submucosal fibroids are the fibroid type most likely to disturb the uterine cavity and fertility.
- Typical leiomyoma microscopy shows intersecting fascicles of uniform smooth-muscle cells.
- Endometriosis causes pain and infertility through recurrent bleeding, inflammation, fibrosis and adhesions.
- An ovarian endometrioma containing altered blood is called a chocolate cyst.
- Plasma cells in endometrial stroma support the diagnosis of chronic endometritis.
- GnRH antagonists suppress gonadotropins rapidly without the initial flare produced by GnRH agonists.
- Clomiphene may cause visual disturbances; gonadotropins may cause ovarian hyperstimulation.
- Pelvic-floor weakness can produce uterovaginal prolapse and stress urinary incontinence.

KMU Exam Trap: Pulsatile GnRH stimulates FSH/LH secretion, whereas continuous GnRH agonist exposure eventually suppresses FSH/LH after receptor down-regulation.

6. ⭐ Starred High-Yield Exam Points
- ⭐ PCOS: insulin resistance + ovarian androgen excess → follicular arrest → anovulatory infertility.
- ⭐ Leiomyoma: sharply circumscribed firm mass with a classic white-gray whorled cut surface.
- ⭐ Endometriosis: ectopic endometrial glands and stroma with recurrent hemorrhage, hemosiderin and fibrosis.
- ⭐ Chronic endometritis: plasma cells in endometrial stroma are the key histological clue.
- ⭐ hCG activates LH receptors and is used to trigger final follicular maturation and ovulation.
- ⭐ Continuous GnRH agonist therapy causes initial flare followed by receptor down-regulation and gonadotropin suppression.
- ⭐ Clomiphene reduces estrogen negative feedback at the hypothalamus and increases GnRH, FSH and LH to induce ovulation.
