*(-) symbol was solely used to indicate the left dominant hand. BMI: Body mass index; FSH: Follicle stimulating hormone; LH: Lutenizing hormone;

PRL: Prolactin; TSH: Thyroid stimulating hormone. Data are expressed as mean ± standard deviation, minimum maximum, and number (percentage).

A P value < 0.05 is considered statistically significant.
