In Vitro Maturation, In Vitro Oogenesis, and Ovarian Longevity. [PDF]

open access: yesReprod Sci, 2023
AbstractThis paper will review a remarkable new approach to in vitro maturation “IVM” of oocytes from ovarian tissue, based on our results with in vitro oogenesis from somatic cells. As an aside benefit we also have derived a better understanding of ovarian longevity from ovary transplant. We have found that primordial follicle recruitment is triggered

The spectrum of in vitro maturation in clinical practice: the current insight

open access: yesFrontiers in Endocrinology, 2023
In vitro oocyte maturation (IVM) has been used worldwide. Despite the long-term implementation, the uptake of this procedure to complement current in vitro fertilization (IVF) remains low.

Effect of follicle size and culture media on in vitro maturation of juvenile porcine oocytes

open access: yesЖивотновъдни науки, 2023
In vitro maturation (IVM) of oocytes is a critical step in the assisted reproductive technologies performed in pigs. The aim of the present study was to determine what effect the use of a particular maturation medium has on the maturation of oocytes ...

Effects of the preservation medium and storage duration of domestic cat ovaries on the maturational and developmental competence of oocytes in vitro

open access: yesThe Journal of Reproduction and Development, 2022
We examined the effectiveness of saline, Euro-Collins solution (EC), and ET-Kyoto solution (ET-K) as preservation media for the cold storage of feline ovaries. Ovaries were maintained in these media at 4°C for 24, 48, or 72 h until oocyte retrieval.
