Laparoscopy procedures are useful tools to perform some assisted reproductive biotechnologies in ewes, it requi-res general anesthesia and manoeuvres that might result alteration of the cardiopulmonary function. For this reason, study aimed investigate effects oxygen supplementation as a therapeutic measure mitigate these alterations ewes submitted laparoscopic ovum pick-up (LOPU) under total i...

Background: After the start of coronavirus disease (COVID-19) pandemic, assisted reproductive services were suspended and restarted in vitro fertilization (IVF) clinics worldwide. In our center we implemented screening all couples for COVID-19 day before starting ovulation cycle ovum pick-up (OPU) procedure. Objectives: Assess prevalence asymptomatic among undergoing (IVF). Design: Cross-sectio...

Abstract In bovine females, the production of embryos derived from oocytes obtained by ovum pick-up (OPU) is becoming a frequent procedure. Collection pre-pubertal animals enables shortening genetic distance, especially in high-value animals. Nevertheless, oocyte and later embryo developmental potential differ between prepubertal adult heifers. The aim this study was to determine possible under...

The benefit of ovarian superstimulation using exogenous FSH before ovum pick-up (OPU) and in vitro embryo production (IVEP) has been the subject conflicting results. objective present study, therefore, was to evaluate effect use dose porcine (p-FSH) OPU/IVEP on response pregnant heifers. Pregnant Holstein heifers (n = 48) were assigned randomly receive 0, 160, or 300 mg NIH-FSH-P1 a crossover d...

The aim of this study was to investigate whether plasma anti-Muellerian hormone (AMH) levels of Holstein-Friesian heifers could be used to predict ovum pick-up (OPU) and embryo production outcomes. Plasma samples and data were collected from 64 heifers, which underwent repeated OPU with subsequent in vitro embryo production followed by embryo flushing after superovulation. AMH levels were signi...
