In vitro maturation and embryo production in cattle.

Effect of Ovarian Cyclic Status on In Vitro Embryo Production in Cattle

P-90: The Effect of Nitric Oxide on Mouse Oocyte in Vitro Maturation in Two and Three Dimensional Conditions

Background: In vitro culture of ovarian follicles may preserve fertility in women with premature ovarian failure due to cancer .It seems that creation a condition that could maintain cellular communications and supports growth of follicles to produce mature oocytes appear to be essential. Nitric oxide (NO) has been recently shown to act with a dual action in mouse oocyte meiotic maturation depe...

The Effects of Progesterone on Oocyte Maturation and Embryo Development

Oocyte maturation and embryo development are controlled by intra-ovarian factors such as steroid hormones. Progesterone (P4) exists in the follicular fluid that contributes to normal mammalian ovarian function and has several critical functions during embryo development and implantation, including endometrial receptivity, embryonic survival during gestation and transformation of the endometrial...

In Vitro Maturation, Fertilization and Embryo Culture of Oocytes Obtained from Vitrified Auto-Transplanted Mouse Ovary

In Vitro Development of Cattle Embryo as Affected By Glucose, Serum and EDTA

Purpose: The aim of this study was to evaluate the effect of different modifications of sequential synthetic oviductal_fluid (SOF) culture system on developmental competence of in vitro matured/fertilized cattle embryos. Materials and Methods: Bovine oocytes were matured and fertilized in vitro and then presumptive zygotes were randomly cultured for up to 9 days in different modifications of SO...

Effect of Β-Mercaptoethanolon Resumption of Meiosis, in Vitro Maturation and Development of Immature Mouse Oocyte Treated With Dehp (Di-(2-Ethylhexy) Phathalae)

Purpose: The aim of this study was evaluated the effect of β -mercaptoethanol on resumption of meiosis, In vivo maturation of immature mouse oocytes treated with DEHP and embryo development. Materials and Methods: NMRI mouse strain (4-6 weeks) were treated daily with 50,µI DEHP Group 1: 121 immature oocytes were matured in MEM-α medium contain FCS 5%, hCG 7.5 IU/ml, rFsH 100mIU/ml, Group 2: 12...
