Participant baseline characteristics.
| Mean ± SEM | ||
|---|---|---|
| Age (years) | 26.5 ± 1.1 | |
| BMI (kg/m2) | 23.9 ± 0.4 | |
| Baseline Reproductive Hormones | LH (IU/L) | 2.6 ± 0.2 |
| Testosterone (nmol/L) | 20.4 ± 0.9 | |
| Baseline trait scores | ||
| STAI-Y Trait | 36.6 ± 1.8 | |
| BIS | 19.4 ± 0.8 | |
| BAS | Drive | 11.6 ± 0.4 |
| Fun | 12.2 ± 0.5 | |
| Reward | 17.5 ± 0.4 | |
| SDI | Dyadic | 44.7 ± 1.4 |
| Solitary | 14.1 ± 1.4 | |
| Total Score | 62.9 ± 2.1 |
Notes: BMI = Body Mass Index; LH = Luteinizing Hormone; STAI-Y Trait = State-Trait Anxiety Inventory to assess trait anxiety; BIS = Behavioural Inhibition System Scale to assess sensitivity to punishment anticipation; BAS = Behavioural Activation System Scale to assess sensitivity to desired goals, fun and reward. SDI = Sexual Desire Inventory to assess dyadic and solitary sexual desire. Results confirmed normal baseline hormone levels, no active anxiety trait, reward responsiveness or sexual desire abnormalities that could confound MRS analysis. n = 19.
