Equol: A Microbiota Metabolite Able to Alleviate the Negative Effects of Zearalenone during In Vitro Culture of Ovine Preantral Follicles

open access: yesToxins, 2019
The impact of zearalenone (ZEN) on female reproduction remains an issue, since its effects may differ among exposed cell types. Besides the use of decontaminants in animal diet, other approaches should be considered to minimise ZEN effects after exposure.

Assessment of different methods of bovine oocytes collection, maturation and Invitro fertilization of abattoir specimens [PDF]

open access: yesIraqi Journal of Veterinary Sciences, 2017
The aim of this study is designed to evaluate the best methods for cow oocytes collection from abattoir specimens which is the cheapest, easily obtained and bulky number. Forty five fresh cow genitalia specimens and testicle were collected directly after

Automatic evaluation of human oocyte developmental potential from microscopy images [PDF]

open access: yes, 2021
Infertility is becoming an issue for an increasing number of couples. The most common solution, in vitro fertilization, requires embryologists to carefully examine light microscopy images of human oocytes to determine their developmental potential. We propose an automatic system to improve the speed, repeatability, and accuracy of this process.

Pregnancy outcome of assisted reproductive technology cycle in patients with hypogonadotropic hypogonadism

open access: yesJournal of Human Reproductive Sciences, 2015
CONTEXT: Ovulation induction in patients with hypogonadotropic hypogonadism (HH) is a challenge to the treating physician. The threshold for ovarian response in HH may differ substantially from that of normal patients.

cAMP Pulsing of Denuded Mouse Oocytes Increases Meiotic Resumption Via Activation of AMP-activated Protein Kinase [PDF]

open access: yes, 2009
cAMP plays a critical role in the control of oocyte maturation, as a high level of cAMP maintains oocyte arrest at the first meiotic prophase. Yet this study shows that pulsing meiotically arrested denuded oocytes (DO) with cAMP induces oocyte maturation

AMP-activated Protein Kinase is Involved in Hormone-induced Mouse Oocyte Meiotic Maturation in vitro [PDF]

open access: yes, 2008
We have previously shown that AMP-activated protein kinase (AMPK) can induce the resumption of meiosis in mouse oocytes maintained in meiotic arrest in vitro.

Effect of different cryopreservation extenders added with antioxidants on semen quality and in vitro embryo production efficiency in cattle

open access: yesAnais da Academia Brasileira de Ciências, 2021
To evaluate the addition of antioxidants in extenders on post-thaw bovine semen quality and in vitro embryo production efficiency. Six semen samples were collected from five Holstein bulls. In the experiment I, the samples were diluted with AndroMed® and

A Knowledge-Based Decision Support System for In Vitro Fertilization Treatment [PDF]

open access: yes, 2022
In Vitro Fertilization (IVF) is the most widely used Assisted Reproductive Technology (ART). IVF usually involves controlled ovarian stimulation, oocyte retrieval, fertilization in the laboratory with subsequent embryo transfer. The first two steps correspond with follicular phase of females and ovulation in their menstrual cycle.
