    Effects of stem cells and amniotic fluid on uterus and ovaries in a rat model of abdominal adhesions: a controlled study
    (GALENOS PUBL HOUSE, 2022-01-01) Aygun, Elif Ganime; Tumentemur, Gamze
    Objective: This study aimed to compare the effects of human umbilical cord mesenchymal stem cells (hUCMSCs), amniotic fluid (AF), and a combination of both on the uterus and ovaries in a rat model of abdominal adhesions.Material and Methods: This study was designed as a controlled study. Four groups, each consisting of six rats, were randomly formed. One group was designated as the control (CNT). hUCMSCs -applied (hUCSC), AF-applied (AMN), and a combination of both (hUCSC + AMN) were the experimental groups. All rats were given intraperitoneal talc powder to create adhesions. After 21 days, animals in experimental groups were further treated with hUCMSC, AF or a combination of these.Results: There was a statistically significant difference in primordial follicle count, endometrial gland number, and endometrial blood vessel count (p<0.05). AMN provided the best results in the endometrial vessel and primordial follicle count. The average endometrial gland count in AMN and hUCSC + AMN was similarly higher than CNT and hUCSC alone.Conclusion: There were significantly higher for counts for endometrial glands, endometrial blood vessels, and primordial follicles in the hUCSC, AMN and hUCSC + AMN groups compared to controls. Animals in the AMN group had the best result for endometrial vessel and highest primordial follicle count. (J Turk Ger Gynecol Assoc 2022

    Effects of Normal Morphology Sperm Count on Fertilization Time in Infertile Couples with Teratospermic Males: An Evaluation with an Embryoscope
    (GALENOS YAYINCILIK, 2022-01-01) Aygun, Elif Ganime; Karabuk, Emine
    Objective: Incubation of the embryo is the vital step in assisted reproductive techniques. Embryoscope systems are incubators that keep the embryo stable and allow for continuous observation without opening the lid. Therefore, the embryo is not displaced and goes through a temperature or air change. The primary aim of this study was to explore the effects of normal morphology sperm count on two pronucleus formation time following intracytoplasmic sperm injection in infertile couples with teratospermic males. The secondary aim was clinical pregnancy. Materials and Methods: Sixty-seven couples undergoing in vitro fertilization were included in this retrospective cohort study. First, intracytoplasmic sperm injection was performed to metaphase II-oocytes. Then, the embryos were placed in an embryoscope (a time-lapse system) for observation. The time that embryos demonstrated two pronuclei were recorded. Demographic and reproductive data were obtained and analyzed. Results: A statistically significant weak correlation was detected between sperm morphology the two pronucleus formation times (r=0.295, p=0.017). Severely decreased normal sperm count was significantly associated with pregnancy with less decreased normal sperm count (p>0.024). Moreover, decreased two pronucleus formation time was significantly associated with pregnancy. Conclusion: A statistically significant, albeit weak, correlation was detected between sperm morphology with two pronucleus formation time. Furthermore, having a lower normal sperm count was related to a higher pregnancy rate than having a higher normal sperm count. Lastly, reduced two pronucleus formation time was significantly associated with pregnancy.
