  1. 1. CRYOPRESERVATION OF HUMAN BLASTOCYSTS, A COMPARISON OF TWO VITRIFICATION AND WARMING KITS

    Kandidat-uppsats, Uppsala universitet/Institutionen för kvinnors och barns hälsa

    Författare :Sara Ottersgård; [2020]
    Nyckelord :Irvine Scientific; Kitazato; human embryos; embryo development; blastocyst scoring;

    Sammanfattning : Infertility is a widespread problem around the world, although the available treatment options constantly improve through research and methodological development. A common treatment option mainly for biologically caused infertility is in-vitro fertilization, where in a menstrual cycle multiple oocytes are stimulated to mature and are then fertilized in a laboratory.

  3. 2. Morphological evaluation of blastocyst after vitrification depending on treatment modality

    M1-uppsats, Uppsala universitet/Forskargrupper (Inst. för kvinnor och barns hälsa)

    Författare :Alexander Tovar Tovar Perez; [2018]
    Nyckelord :embryo biopsy; assisted reproductive technology; embryo morphology; preimplantation genetic diagnosis; refrozen;

    Sammanfattning : Assisted reproductive technology procedures has become a more complex treatment over the years after implementation of preimplantation genetic diagnostics and cryopreservation methods such as slow freeze and vitrification. When embryos undergo these methods they are exposed to external damage that threaten to affect their quality and thereby lead to lower survival rates and lower pregnancy rates. LÄS MER

  4. 3. Evaluation of VitriBlast™ for vitrification of immature oocytes

    Magister-uppsats, Institutionen för kvinnors och barns hälsa

    Författare :Fatma Gülen Yaldir; [2013]
    Nyckelord :oocytes; fertility preservation; vitrification; VitroLoop; Cryopette;

    Sammanfattning : Cryopreservation of gametes and embryos is crucial in fertility treatment and fertility preservation. Preservation of oocytes is a more complicated process than preservation of sperm and embryos. LÄS MER

  5. 4. Cryopreservation of Oocytes : Comparison between the Cryoloop and the Cryopette vitrification techniques

    Magister-uppsats, Institutionen för medicinsk biokemi och mikrobiologi

    Författare :Sara Ekberg; [2010]
    Nyckelord :Oocytes; cryopreservation; vitrification; Cryoloop; Cryopette;

    Sammanfattning : Crypreservation of oocytes is recently being considered to be a valid choice in infertility treatments.Low survival and fertilization rates due to inefficient slow freeze protocols have been the outcome ofmany previous studies done in the field. LÄS MER

  7. 5. Morphological characterisation and cryopreservation of sweet potato, Ipomoea batatas (L.) Lam., accessions at the NPGRC of South Africa

    Master-uppsats, SLU/Swedish Biodiversity Centre

    Författare :Machoene Tshidi Manamela; [2009]
    Nyckelord :cryopreservation; duplicate accessions; germplasm; morphological characterisation; NPGRC; phenotypic diversity; sweet potato ; South Africa;

    Sammanfattning : Morphological characterisation of germplasm helps in the identification of duplicate accessions, unique traits and the development of core collection. Cryopreservation serves as a complementary conservation method to field and in-vitro methods. LÄS MER
