Effect of In Vitro Maturation Technique and Alpha Lipoic Acid Supplementation on Oocyte Maturation Rate: Focus on Oxidative Status of Oocytes.

International journal of fertility & sterility, 2016
Therapeutic potential of in vitro maturation (IVM) in infertility is growing with great promise. Although significant progress is obtained in recent years, existing IVM protocols are far from favorable results. The first aim of this study was to investigate whether two step IVM manner change reactive oxygen species (ROS) and total anti- oxidant ...

The effect of C–C motif chemokine ligand 2 supplementation on in vitro maturation of porcine cumulus-oocyte complexes and subsequent developmental competence after parthenogenetic activation

Frontiers in Veterinary Science, 2023
Porcine embryos are used for a variety of applications. However, the maturation rate in vitro remains low, and novel in vitro maturation (IVM) techniques that facilitate the collection of mature oocytes are necessary.

Effect of preantral follicle isolation technique on in-vitro follicular growth, oocyte maturation and embryo development in mice [PDF]

Human Reproduction, 2002
The use of mechanical and enzymatic techniques to isolate preantral follicles before in-vitro culture has been previously described. The aim of this study was to assess the effect of the isolation procedure of mouse preantral follicles on their subsequent development in vitro.Follicles were isolated either mechanically or enzymatically and cultured ...

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

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 ...
