Novel Concepts for Inducing Final Oocyte Maturation in In Vitro Fertilization Treatment

open access: yesEndocrine reviews, 2018
Infertility affects one in six of the population and increasingly couples require treatment with assisted reproductive techniques. In vitro fertilization (IVF) treatment is most commonly conducted using exogenous FSH to induce follicular growth and human

Comparison of oocyte collection methods using caprine ovaries and in vitro embryo culture

open access: yesApplied Animal Science, 2022
Objective: The objectives of this study were to elucidate the efficiency of oocyte recovery through different techniques, grading of oocytes, and optimization of the caprine in vitro embryo production system. Materials and Methods: Ovaries were collected

Follicle priming by FSH and pre-maturation culture to improve oocyte quality in vivo and in vitro.

open access: yesTheriogenology, 2020
Nowadays there is strong demand to produce embryos from premium quality cattle, and we can produce embryos using oocytes collected from living premium animals by ovum-pick up (OPU) followed by in vitro fertilization (IVF).

Comparison of Two In vitro Maturation Media in Their Efficiency for Production of Competent Alpaca Oocytes

open access: yesJournal of Animal Science and Research, 2022
Oocyte maturation is the most critical process in in vitro culture, since the oocyte acquires competence for future processes, which involve the resumption of meiosis, epigenetic regulation, polyspermy block, activation of the zygote, exchange of ...

All-trans retinoic acid and fibroblast growth factor-2 enhance the fertility rate and embryo development in polycystic ovary syndrome mouse model [PDF]

open access: yesIranian Journal of Basic Medical Sciences
Objective(s): Polycystic ovary syndrome (PCOS) causes a developmental arrest of antral follicles and disrupts oocyte maturation. Retinoic acid (RA) and Fibroblast Growth Factor-2 (FGF2) are effective in follicle growth, thus their effects on ...

BPA and BPS affect the expression of anti-Mullerian hormone (AMH) and its receptor during bovine oocyte maturation and early embryo development

open access: yesReproductive Biology and Endocrinology, 2021
Background Exposure to endocrine-disrupting chemicals, such as Bisphenol A (BPA) and Bisphenol S (BPS), is widespread and has negative implications on embryonic development.

The Effect of Omega-3 on In Vitro Maturation of Mouse Oocytes at the Stage of Germinal Vesicle

open access: yesMajallah-i Dānishgāh-i ̒Ulūm-i Pizishkī-i Qum, 2020
Background and Objectives: Studies have shown that fatty acids affect maturation of oocytes, however, studies carried out on the effect of omega-3 on in vitro maturation of oocytes, are limited.

The variable success of in vitro maturation: can we do better? [PDF]

open access: yes, 2018
The efficiency of in vitro assisted reproductive technologies, consisting of the transfer of embryos obtained in vitro through in vitro maturation, in vitro fertilization and early embryo culture is still limited.

Current state and future possibilities of ovarian tissue transplantation

open access: yesReproductive Medicine and Biology, 2019
Background As a result of recent developments in cancer treatment, cancer survivorship and survivors' quality of life have been emphasized. Although ovarian tissue cryopreservation (OTC) is an experimental technique, it would be the sole technique for ...
