  1. 1. Hormonal and paracrine influences on Leydig cell steroidogenesis

    Författare :Nina Renlund; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Androgen production by Leydig cells is critical for development of the male reproductive organs and for maintaining normal body homeostasis and fertility later in life. Biosynthesis of testosterone is driven by secretion of the gonadotropin, luteinizing hormone (LH) from the pituitary. LÄS MER
