Errors in chromosome segregation during oogenesis and early embryogenesis [PDF]

, 2010
Errors in chromosome segregation occurring during human oogenesis and early embryogenesis are very common. Meiotic chromosome development during oogenesis is subdivided into three distinct phases.

EFFECT OF CYSTEAMINE ON THE RATE OF IN VITRO MATURATION OF OOCYTES IN TWO MEDIA [PDF]

Acta Medica Iranica, 2006
Rate of in vitro maturation of oocytes is one of the challenges of assisted reproductive techniques. In this study we investigated the effects of supplementation of cysteamine on the rate of in vitro maturation of oocytes in two different media. Germinal

Welfare in horse breeding [PDF]

, 2015
Welfare problems related to the way horses are bred, whether by coitus or by the application of artificial reproduction techniques (ARTs), have been given no discrete consideration within the academic literature. This paper reviews the existing knowledge

Follicular fluid content and oocyte quality: from single biochemical markers to metabolomics [PDF]

, 2009
The assessment of oocyte quality in human in vitro fertilization (IVF) is getting increasing attention from embryologists. Oocyte selection and the identification of the best oocytes, in fact, would help to limit embryo overproduction and to improve the ...

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

Reproductive 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.

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

Iranian 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 ...

Effect of collection techniques on cumulus oocyte complexes (COCs) recovery, in vitro maturation and fertilization of goat oocytes

African Journal of Biotechnology, 2011
تم إجراء التجربة لدراسة تأثير تقنيات الجمع على تعافي مجمعات البويضات الركامية (COCs)، والنضج في المختبر (IVM) والإخصاب في المختبر (IVF) لبويضات الماعز. تم جمع COCs من خلال ثلاث تقنيات هي الوخز، وتقطيع وشفط مبيضات الماعز التي تم الحصول عليها في المسلخ. لوحظ أن العدد الإجمالي لـ COCs/المبيض وكذلك عدد COCs/المبيض غير الطبيعي كان أعلى بكثير (p < 0.01) في ...

Sequential analysis of global gene expression profiles in immature and in vitro matured bovine oocytes: potential molecular markers of oocyte maturation

BMC Genomics, 2011
Background Without intensive selection, the majority of bovine oocytes submitted to in vitro embryo production (IVP) fail to develop to the blastocyst stage. This is attributed partly to their maturation status and competences.
