Measure
Fluoxetine
Participants will receive treatment with fluoxetine for 2 months Fluoxetine: Participants will begin taking 10 mg of fluoxetine, once a day by mouth, on the first day of their second menstrual cycle during the study. Dosage will be increased to 20 mg of fluoxetine once a day after 7 days, to be maintained until the luteal phase (start of ovulation) of menstrual cycle 3. If side effects are intolerable, the dose will be lowered to 10 mg of fluoxetine per day. Participants will undergo a total of 2 months of treatment with fluoxetine.
Bupropion
Participants will receive treatment with bupropion for 2 months Bupropion: Participants will begin taking 150 mg of bupropion, once a day by mouth, on the first day of their second menstrual cycle during the study. Dosage will be increased to 300 mg of bupropion once a day after 7 days, to be maintained until the luteal phase of menstrual cycle 3. If side effects are intolerable, the dose will be decreased to 150 mg of bupropion per day. Participants will undergo a total of 2 months of treatment with bupropion.

PRIMARY outcome

Timeframe: Measured in baseline menstrual cycle and during antidepressant treatment for two menstrual cycles

Population: All subjects enrolled were included in the mixed model analysis. For mean results at each timepoint in the data table below, some subjects were not included due to missing blood samples or samples collected outside the specified cycle phase window.

Hormone levels at early follicular, ovulation, and luteal phase of 3 menstrual cycles which included baseline, month 1 of daily antidepressant treatment and month 2 of daily antidepressant treatment. Effects of the two antidepressant treatments and menstrual cycle on hormone level were examined.

Population: All subjects enrolled were included in the mixed model analysis. For mean results at each timepoint in the data table below, some subjects were not included due to missing questionnaire samples or samples collected outside the specified cycle phase window.

A five-item scale with each item scored from 1 to 6. Score range is 5 to 30. Higher scores indicate more sexual dysfunction. Scores at early follicular, ovulation, and luteal phase of 3 menstrual cycles which included baseline month, month 1 of daily antidepressant treatment and month 2 of daily antidepressant treatment. Differential effects of the two antidepressant treatments and menstrual cycle on ASEX scores were examined.

Population: All subjects enrolled were included in the mixed model analysis. For mean results at each timepoint in the data table below, some subjects were not included due to missing blood samples or samples collected outside the specified cycle phase window.

Free testosterone was calculated from total testosterone ng/ml divided by sex hormone binding globulin (SHBG) nmol/l multiplied by 100. Hormone levels at early follicular, ovulation, and luteal phase of 3 menstrual cycles which included baseline month, month 1 of daily antidepressant treatment and month 2 of daily antidepressant treatment. Differential effects of the two antidepressant treatments and menstrual cycle on hormone levels were examined.
