What does an Obstetrician and Gynecologist (OBGYN) like Dr. Hasen do?

An Obstetrician and Gynecologist (OBGYN), like Dr. Hasen, is a medical doctor specializing in women's reproductive health, pregnancy, and childbirth. They provide care throughout a woman's life, including prenatal care, labor and delivery, postpartum support, diagnosis and treatment of gynecological conditions (e.g., infections, fibroids, endometriosis, menstrual disorders), family planning, contraceptive management, preventative screenings like Pap tests, and management of menopausal symptoms.

How often do I need a Pap test, and what is it for?

A Pap test (or Pap smear) is a screening procedure for cervical cancer. It checks for precancerous or cancerous cells on the cervix. Guidelines vary slightly by province but are generally recommended for women starting around age 21-25 (or once sexually active) and continuing every 2-3 years if results are normal. The frequency may change based on your age, medical history (including HPV status), and previous Pap test results. Dr. Hasen will advise you on the appropriate screening schedule for your individual circumstances based on current provincial guidelines.

When should a teenager have her first OBGYN visit, and what does it involve?

The first visit to an OBGYN for a teenager is often recommended between ages 13-15, or sooner if there are specific concerns like very painful periods, irregular cycles, or questions about sexual health. This initial visit may not involve a pelvic exam unless there's a specific medical reason. It's primarily an opportunity to build a rapport with Dr. Hasen, discuss normal development, menstrual health, contraception, STI prevention, and answer any questions in a confidential setting.

What are some common gynecological surgeries Dr. Hasen might perform?

Common gynecological surgeries include procedures like hysterectomy (removal of the uterus), oophorectomy (removal of ovaries), tubal ligation (female sterilization), D&C (dilation and curettage), endometrial ablation, and surgeries to treat conditions such as fibroids (myomectomy), endometriosis, ovarian cysts, or pelvic organ prolapse. Many of these can be performed using minimally invasive techniques like laparoscopy or hysteroscopy.
