21. Epididymal and accessory sex gland function and semen quality
Sammanfattning : Infertility, defined as the inability to conceive after one year of unprotected regular intercourse, affects up to 15% of all couples of reproductive age. The infertility can originate from female, male or both partners. In up to 50% of the affected couples, a male factor is the cause of infertility. LÄS MER
22. Genital mutilation of girls in Sudan : community- and hospital-based studies on female genital cutting and its sequelae
Sammanfattning : Background: In spite of many decades of campaigns, female genital mutilation (FGM) is still highly prevalent in Sudan. One reason for this might be that campaigns have failed to approach fundamental values of FGM. LÄS MER
23. The fate of primary aneuploid cells in early embryonic development and stem cells
Sammanfattning : Chromosomal aberrations occurring during gametogenesis and early embryonic development play a significant role in infertility and fetal loss in humans. Germ cells that have an abnormal number of chromosomes (aneuploidy) are generated mainly due to errors during female gamete formation, a phenomenon increasing in occurrence with age. LÄS MER
24. Preserving Genetic Integrity in Reproduction: Insights from Telomere Protection and Sperm Head-Tail Junctions
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
25. Studies on genetic aberrations as possible predictors of the outcome of assisted reproduction
Sammanfattning : Traditionally, diagnosis of male infertility has relied upon microscopic assessment of semen. The normality criteria set by the World Health Organization (WHO) in regard to sperm concentration, motility and morphology are, however, poor predictors of fertility. LÄS MER
