Dynamics of Blood Serum Levels of Follicle-Stimulating Hormone, Luteinizing Hormone, Prolactin, Estradiol, and Progesterone in Right- and Left-Handed Women

Abstract

The dynamics of follicle-stimulating hormone (FSH) luteinizing hormone (LH), prolactin (PRL), estradiol (E2), and progesterone were studied in left- and right-handed women having a stable 28-day menstrual cycle. The hormones were determined by enzyme immunoassays on days 3, 8, 10, 13, 16, 22, 26, and 28 of the menstrual cycle. The data showed that bllod serum levels of FSH, LH, PRL, and E2are higher in left-handed in comparison to right-handed women (p< 0.001). On days 10 through 28 of the cycle, the level of progesterone is also higher in left-handed women (p< 0.001). The dynamic of these hormones in left-handed and right-handed women appeared to remain within the normal limits. These findings indicate that the handedness correlates with the dynamucs of serum levels of these hormones. Higher serum levels of hormones in left-handed women suggests that they have higher levels of the functional activity of the hypophysis–ovarian axis and prolactin axis.
