Optimization of ovum pick-up-in vitro fertilization and in vitro growth of immature oocytes in ruminants. [PDF]

J Reprod Dev
Due to the strong demand for embryo production from young and genotyped superior animals using ovum-pick up (OPU) combined with in vitro fertilization (IVF), the number of in vitro-produced embryos has exceeded that of in vivo-derived embryos globally ...

Rescue intrauterine insemination in women failing to retrieve oocytes at ovum pick-up: report of a case series. [PDF]

J Assist Reprod Genet
Failure to collect oocytes at the time of oocyte pick-up is an unfavorable outcome of in vitro fertilization (IVF) cycles. In these cases, prompt intrauterine insemination (IUI) could be an option (rescue IUI), but this possibility has been poorly ...

Oxidative stress in donor mares for ovum pick-up delays embryonic development

Theriogenology, 2023
The in vitro production of equine embryos via ovum pick-up (OPU) and intracytoplasmic sperm injection (ICSI) has increased rapidly. There is a marked effect of the individual mare on the outcome of OPU-ICSI, but little is known about the influence of the mare's health condition.

Effects of superstimulation with fsh on follicular population and recovery rate of oocytes in the growing phase of the first and second follicular wave

Veterinární Medicína, 2002
Effectiveness of in vitro production of embryos (IVP) is limited among other factors by the recovery rate of oocytes. Gonadotropin superstimulation can improve the recovery rate of oocytes.

In vitro production of bovine embryos derived from individual donors in the Corral® dish [PDF]

, 2017
Background: Since the identity of the embryo is of outmost importance during commercial in vitro embryo production, bovine oocytes and embryos have to be cultured strictly per donor.
