Cyclic hormonal contraception may attenuate premenstrual symptoms, but that the timing of symptoms is similar regardless of hormonal contraception use.

‘Better understanding the psychological and physical effects of hormonal contraception could help guide clinicians in the diagnosis and treatment of premenstrual syndrome (PMS).’

The researchers report changes in menstrual cycle symptom scores for
variables such as depression, anger, irritability, and physical
symptoms between cyclic hormonal contraception users and nonusers. They
found that cyclic hormonal contraception may attenuate premenstrual
symptoms, but that the timing of symptoms is similar regardless of
whether the subjects used hormonal contraception. 




Better understanding the psychological and physical effects of hormonal contraception could help guide clinicians in the diagnosis and treatment of premenstrual syndrome (PMS).
"Because women taking hormonal contraceptives are routinely excluded from studies of PMS and premenstrual dysphoric disorder (PMDD), this study provides a valuable examination of the influence of exogenous hormones on premenstrual symptom expression and response to treatment," says Robert Downs, Deputy Editor of Journal of Women’s Health, Richmond, VA.
