Normal Menstrual cycle (cervical discharge)

is a white, odorless cervical discharge composed of cervical mucus, normal vaginal flora, and vaginal squamous epithelium.

Increasing amounts of this normal vaginal discharge typically occurs midcycle (eg, 10-14 days after previous menses) as estrogen levels increase prior to ovulation, and then regresses.

Without manifestations of infection such as pruritus, erythema, pain, or a malodorous discharge.

Prior to the diagnosis of physiologic leukorrhea, other causes of increasing vaginal discharge must be excluded.

Polymorphonuclear leukocytes on microscopic examination are evidence of a local immune response (eg, inflammation) to infection.

Microscopic examination reveals a predominance of squamous cells and rare polymorphonuclear leukocytes.

This patient has rare polymorphonuclear leukocytes on microscopy, ruling out all infectious etiologies as the cause of her discharge.
