  • Title: Sexual dimorphism of the weight of internal organs in fetal ontogenesis.
    Author: Marecki B.
    Journal: Anthropol Anz; 1989 Jun; 47(2):175-84. PubMed ID: 2774521.
    Abstract:
    The paper contains results of the investigation on the sexual differentiation of the weight of brain, heart, lungs, liver, spleen, kidneys, adrenal glands and thymus. The studies were carried out on a total of 632 fetuses (349 males and 283 females) and 1276 newborns (795 males and 481 females) in the age from 17 to 43 weeks of life. The study of sexual dimorphism of internal organs concludes that in the period of fetal development of man this dimorphism is weakly developed.
