21. Effects of endocrine disruptors on adreno-cortical and Leydig cell steroidogenesis
Abstract : A common sequential pathway for steroidogenesis, designed to produce steroid hormones, is expressed in the adrenal cortex, testes and ovaries. In this process, cholesterol is converted to all known steroids by specific enzymes in a tissue-specific manner. READ MORE

22. Endometrial receptivity and development of new contraceptive methods
Abstract : Ovulation and endometrial development as well as contraceptive efficacy was studied after treatment with the antiprogestin mifepristone. Mechanism of action after treatment with the gestagen levonorgestrel or mifepristone in doses effective for emergency contraception was also evaluated. READ MORE

23. Endometrial receptivity and regeneration in health and disease : molecular, cellular and clinical perspectives
Abstract : Each month, the endometrium regenerates under the influence of the ovarian hormones and builds up to a receptive state in preparation for embryo implantation. In the absence of pregnancy, it sheds during menses and the regenerative cycle starts again. READ MORE

24. Identification and characterization of stem Leydig cells in the testis
Abstract : In the testis, several cell types are needed to ensure male fertility, among them the testosterone-producing Leydig cells. Testosterone supports the maturation of sperm and maintains the male phenotype. Functional Leydig cells are therefore required to prevent testicular malfunction. READ MORE

25. Hormonal and paracrine influences on Leydig cell steroidogenesis
Abstract : 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. READ MORE
