Follicular wave synchronization prior to ovum pick-up

Theriogenology, 2020
Among the reproductive biotechnologies, in vitro embryo production (IVEP) is an important tool for multiplying genetic material of superior merit. Recently, the number of embryos produced and transferred in vitro became significantly higher than that produced in vivo worldwide.

Artificial ovum pick‐up chamber

Makromolekulare Chemie. Macromolecular Symposia, 1988
AbstractAn artificial implantable ovum pick‐up and transfer chamber was developed for a treatment of patients suffering from infertility caused by tubal defects. The first chamber prototypes were made of Cardiomat 610 polyetherurethane using a dipping technique.

Repeated endoscopic ovum pick-up in sheep

Theriogenology, 1999
Endoscopy is an effective and minimally invasive technique which offers the possibility of repeated ovum pick-up (OPU). In this study 4 different treatment programs (Groups A, B, C and D) for repeated endoscopic OPU in sheep were investigated. The number of follicles and oocytes, quality of cumulus-oocyte-complexes (COCs), and detectable effects on ...

Repeated ovum pick-up in Italian Mediterranean buffalo cows

Theriogenology, 1996
The potential of the ovum pick-up technique, used over a long period, was evaluated in 6 Italian Mediterranean buffalo cows that had more than 500 d open. The cows were submitted to ovum pick-up twice weekly for 2 mo. An additional 2-mo cycle of ovum pick-up was performed in 3 of the buffalo.

Progesterone Device Use Improves Ovum Pick-Up Efficiency in Acyclic Donors

Journal of Equine Veterinary Science, 2023
The aim of this study was to evaluate follicular dynamics and ovum pick-up (OPU) efficacy in untreated mares or mares treated with an intravaginal progesterone (P4) device during seasonal anestrus (acyclic) and during the breeding season (cyclic). Six mares (mean age = 5 years), were recruited into an ovum pick-up scheme that was performed every 14 ...
