MRI data show impact of oral contraceptives on gland volume

Key clinical point: Women taking oral contraceptives showed lower volume in the hypothalamic and pituitary gland compared to normally cycling women based on magnetic resonance imaging (MRI) data.

Major finding: Hypothalamic and pituitary volumes were significantly lower in women using oral contraceptives compared to naturally cycling women (B = -81.2 for both; P = 0.002 and P = -0.04, respectively).

Study details: The data come from a prospective study of 50 healthy women aged 18 and older, including 21 oral contraceptive users, and 29 naturally cycling women.
