Table 4. Hormonal levels of participants in the bariatric surgery and control groups at 3, and 6-months follow-up

Hormonal levels	Mean±SD		p-value
Hormonal levels	Bariatric surgery group	Control group	p-value
3-month FU
FSH (mIU/mL)	10.4±3.2	8.1±2.5	0.002^*
LH (mIU/mL)	6.2±2.1	4.8±1.6	0.01^*
Estrogen (pg/mL)	75.6±12.1	77.8±11.5	0.6
Progesterone (ng/mL)	0.9±0.3	0.8±0.2	0.4
6-month FU
FSH (mIU/mL)	11.6±3.5	8.3±2.8	0.001^*
LH (mIU/mL)	6.8±2.3	4.9±1.7	0.009^*
Estrogen (pg/mL)	58.3±12.9	76.9±11.8	0.4
Progesterone (ng/mL)	0.8±0.2	0.8±0.2	0.8

Indicates statistically significant difference (p<0.05) between the bariatric surgery group and the control group. FSH and LH levels were significantly increased in the bariatric surgery group compared to the control group at both 3-month and 6-month follow-up periods, while there was no significant difference in estrogen and progesterone levels between the two groups at 3-month and both time points, respectively. While there is a significant decrease in estrogen levels in the bariatric surgery group at 6 months follow-up compared to baseline (p<0.001) and compared to the control group at 6 months. However, as we mentioned, there is no significant difference between the groups at baseline or at 3 months follow-up.
