Menstruation and Ovulation After Bilateral Oophorectomy: Absent

Bilateral oophorectomy (removal of both ovaries) causes surgical menopause.

• No ovulation – no oocytes remain.
• No menstruation – no ovarian estrogen/progesterone → no endometrial proliferation/shedding.
• Hormonal consequences – abrupt loss of estradiol, progesterone, testosterone → vasomotor symptoms, bone loss, urogenital atrophy, cardiovascular risk.

Management

• Hormone therapy (HT) – estrogen ± progestin (if uterus intact) until average natural menopause age (~51), then reassess.
• Non-hormonal options for symptoms if HT contraindicated.
• Bone density monitoring, cardiovascular risk reduction.

If uterus remains, cyclic progestin induces withdrawal bleeding but this is not a true period (no ovulation).
