Changes in the menstrual bleeding of users of a subdermal contraceptive implant of nomegestrol acetate (Uniplant) do not influence sexual frequency, sexual desire, or sexual enjoyment.

OBJECTIVE

To evaluate the effect of menstrual changes induced by a nomegestrol acetate subdermal contraceptive implant (Uniplant; Thermex, Bahia, Brazil) on users' sexuality.

DESIGN

Prospective observational survey.

SETTING

San Borja-Arriarán Hospital, University of Chile, School of Medicine.

PATIENT(S): Normally cycling healthy women and their partners.

INTERVENTION(S): Structured interview before and during use of the contraceptive.

MAIN OUTCOMES MEASURE(S): Sexual frequency, desire, and enjoyment; perception of health; and contraceptive satisfaction.

RESULT(S): During the use of the implant more women reported irregular cycles (32% versus 11%) and vaginal spotting (38% versus 19%). Frequency of sexual relations was unchanged (2.3 versus 2.5/wk) but the percent of couples engaging in sexual relations during vaginal spotting increased (28% versus 11%). There was no significant difference in the percent of men or women who reported an increase, or decrease, in perceived sexual desire, sexual enjoyment, or perception of health during the use of Uniplant.

CONCLUSION(S): Despite the alterations in menstrual cyclicity and the occurrence of spotting, the use of a contraceptive subdermal implant of nomegestrol acetate did not effect desire for, enjoyment of, or frequency of sexual relations in users.
