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

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

    Abstract : 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. READ MORE

  4. 12. The impact of genetic, environmental and life-style factors on male reproductive function

    Author : Jonas Richthoff; Malmö Reproduktionsmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; male reproductive function; testicular cancer; smoking; Medicin människa och djur ; Medicine human and vertebrates ; cryptorchidism; sperm concentration;

    Abstract : Recent studies have indicated a decline in sperm number in the western world during the past 50 years, sperm concentration changing from 113 to 66 millions per mL. Furthermore, significant geographical differences in male reproductive function have been observed. READ MORE

  5. 13. Pre- and post-copulatory sexual selection in the fowl, Gallus gallus

    Author : Hanne Løvlie; Sven Jakobsson; Tommaso Pizzari; Matthew J. G. Gage; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cryptic female choice; Gallus; inbreeding avoidance; mate choice; sexual conflict; sexual selection; sperm competition; Ethology and behavioural ecology; Etologi och beteendeekologi; etologi; Ethology;

    Abstract : The evolutionary goal of individuals is reproduction and sexual selection favours traits improving reproductive success. When males invest less than females in offspring, males have potentially a higher reproductive rate than females. READ MORE

  6. 14. Safety and quality aspects of IVF - neonatal and maternal outcomes following advanced techniques

    Author : Erica Ginström Ernstad; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; blastocyst transfer; frozen embryo transfer; vitrification; preimplantation genetic testing; neonatal outcome; maternal outcome;

    Abstract : Background: Singletons born following assisted reproductive technology (ART) have adverse neonatal outcome compared to singletons born following spontaneous conception (SC). Moreover, the women undergoing ART are at an increased risk of hypertensive disorders in pregnancy (HDP) and placental complications. READ MORE

  7. 15. Ovarian Reserve and Assisted Reproduction

    Author : Thomas Brodin; Jan Holte; Matts Olovsson; Lars Berglund; Juha Tapanainen; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; AFC; AMH; anti-Müllerian hormone; antral follicle count; follicle-stimulating hormone; FSH; ICSI; infertility; intracytoplasmic sperm injection; in vitro fertilization; IVF; LH; live birth; luteinizing hormone; menstrual cycle; menstrual cycle length; ovarian reserve; pregnancy; reproductive endocrinology; reproductive technology; Medicinsk vetenskap; Medical Science;

    Abstract : Treatment success in IVF-ICSI is mainly limited by female age, but differences in ovarian reserve (OR; the remaining pool of oocytes and their quality) between individuals modify treatment prerequisites among women of similar age. OR may be assessed by OR tests (ORTs). READ MORE
