Menstrual and Hormonal Disorders
- Polycystic Ovary Syndrome (PCOS): A common hormonal disorder among women of reproductive age, characterized by irregular periods, excess androgen levels, and/or polycystic ovaries on ultrasound.
- Thyroid Disorders affecting Gynecologic Health: Conditions like hypothyroidism or hyperthyroidism that can impact menstrual cycles, fertility, and pregnancy outcomes.
- Abnormal Uterine Bleeding (Heavy, Irregular, Prolonged Periods): Menstrual bleeding that is different in frequency, duration, or amount than what is typical for an individual, requiring investigation.
Gynecologic Cancers and Precancerous Conditions
- Cervical Dysplasia (CIN) & Cervical Cancer: Precancerous changes (Cervical Intraepithelial Neoplasia) or malignant tumors of the cervix, the lowermost part of the uterus, often linked to HPV infection.
- Endometrial Hyperplasia & Uterine (Endometrial) Cancer: Precancerous thickening of the uterine lining (endometrial hyperplasia) or cancer that begins in the lining of the uterus (endometrium).

- Endometrial Ablation & Resection: Minimally invasive procedures to destroy or remove the lining of the uterus (endometrium) to treat heavy menstrual bleeding in appropriate candidates.
- Basic Infertility Workup & Ovulation Tracking: Initial investigations into causes of infertility and guidance on tracking ovulation.
