Serum Levels of Female Sex Hormones in Left-handed and Right-handed Menopausal Women

Abstract

The study covered 25 left-handed and 27 right-handed clinically healthy females aged between 47 and 55 years during normal menopause. It was carried out in the third year from the beginning of amenorrhoea. The levels of the follicle-stimulating hormone, luteinising hormone, proclactin, estradiol, and progesterone were determined by means of enzyme-immunological methods with IMX (Abbott, USA) and Serozyme I (Biochem Immunosystem Diagnostica, USA) apparatuses. It was established that in left-handed women the serum concentrations both of the follicle-stimulating hormone and luteinising hormone were significantly higher (P <.001), and those of prolactin, estradiol, and progesterone much lower (P <.001), as compared to the right-handed women.
