  4. 18. New micromanipulative techniques in reproductive biology

    Författare :José Inzunza; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : New micro manipulative techniques have facilitated development to help patients who suffer from infertility and spontaneous abortion, as well as those who carry severe genetic diseases and have risks of delivering an affected child. Preimplantation genetic diagnosis (PGD), which is based on obtaining blastomere biopsy from an eight-cell embryo, has made it possible to diagnose severe defects caused by a genetic factor. LÄS MER

  5. 19. Steroid metabolism in human reproductive organs

    Författare :Anna Helena Karypidis; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Androgens are involved in the development of prostate cancer. Both UGT2B17 and CYP7B1 are involved in the metabolism of androgens and are highly abundant in the prostate. Deletion of the UGT2B17 gene is associated with low or undetectable urinary testosterone levels. LÄS MER
