Abstract Study question Does frozen-thawed sperm show an impact on success rates in ICSI with autologous oocyte cycles compared to fresh samples? Summary answer The slight decrease cumulative live birth (CLBR) using samples should not overshadow the benefits offered by freezing. What is known already Sperm freezing offers many advantages for cycle planning, logistics, sample safekeeping and pat...

During in vitro fertilization treatment (IVF), a surplus of oocytes is produced which results in a surplus of embryos which must be preserved. Due to the recent tendency in ART treatment to transfer fewer embryos in order to avoid multiple pregnancies, partly a result of new laws and guidelines aimed at controlling the number of embryos to be transferred and the number of oocytes to be fertiliz...

Abstract Investigation of cellular responses to thermal heat stress can lead identifying novel targets intervention tackle the increasing fertility decline due climate change-associated seasonal stress. We aimed study response granulosa cells Dry beef cows (n=11) were kept together during and subjected synchronization stimulation for follicular dynamics. Ovum pick-up (OPU) was conducted on all ...

BACKGROUND Oocyte cryopreservation is an important method used in a number of human fertility circumstances. Here, we compared the survival, in vitro maturation, fertilization, and early embryonic development rates of frozen-thawed human immature oocytes using two different cryopreservation methods. METHODS A total of 454 failed-matured oocytes [germinal vesicle (GV) and metaphase I (MI) stag...

Background Cryopreservation of semen requires optimized conditions to minimize the harmful effects of various stresses. The main approach for protection of sperm against stress is based on the use of antioxidants and cryoprotectants, which are described as defensive methods. Recently, the application of controlled mild stressors has been described for activation of a temporary response in oocyt...
