  1. 1. EXPOSURE TO PERSISTENT ORGANOCHLORINE POLLUTANTS AND MALE SEMEN FUNCTION

    Författare :Anna Rignell-Hydbom; Avdelningen för arbets- och miljömedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Miljömedicin; Environmental health; epididymal and accessory sex gland function; Y:X sperm chromosome ratio; sperm chromation integrity; sperm concentration; sperm motility; persistent organochlorine poluutants;

    Sammanfattning : Persistent organochlorine pollutants (POPs), such as polychlorinated biphenyls (PCB) and the insecticide dichloro-diphenyl-dichloro-ethylene (DDT) have been released into the environment mainly since the second World War. POPs accumulate especially in highly ranked predators of the aquatic food chain. LÄS MER

  3. 2. Cancer and male reproductive function- the effect on sperm DNA integrity and on birth outcomes in the offspring

    Författare :Olof Ståhl; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SCSA; birth outcomes; sperm DNA integrity; male cancer; fertility;

    Sammanfattning : Male cancer survivors (MCS) are at risk of suffering from impaired fertility. Male fertility is dependant on sperm DNA quality. The Sperm Chromatin Structure Assay (SCSA) reflects the proportion of sperm with poor DNA, the DNA fragmentation index, DFI. LÄS MER

  4. 3. Preserving Genetic Integrity in Reproduction: Insights from Telomere Protection and Sperm Head-Tail Junctions

    Författare :Kexin Zhang; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Reproductive biology;

    Sammanfattning : This doctoral thesis embarks on a meticulous exploration of genetic integrity within the expansive domain of reproductive biology. Its overarching objective is to decipher the intricacies that underlie the preservation of hereditary stability across generations. LÄS MER

  5. 4. The interplay between chromosome structure and meiotic integrity

    Författare :Ingrid Lilienthal; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Sexually reproducing organisms employ a specialized cell division called meiosis to form unique, haploid gametes from a diploid precursor cell. Upon fertilization, two opposite-sex gametes fuse to create a zygote that will develop into the offspring. LÄS MER

  7. 5. Reproductive function in male childhood cancer survivors

    Författare :Patrik Romerius; Malmö Reproduktionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Childhood Cancer SurvivorsFertilityHypogonadismSperm DNA IntegrityAzoospermiaEstrogen Receptor alpha polymorphism;

    Sammanfattning : Childhood cancer (CC) survival rate has increased over the last couple of decades, today approaching 80%. Therefore more attention has been paid to late effects. One important issue for CC survivors (CCS) is impaired reproductive function. LÄS MER
