pontaneous embryonic loss after in vitro ertilization with and without ntracytoplasmic sperm injection

Pregnancy Rate after First Intra Cytoplasmic Sperm Injection-In Vitro Fertilisation Cycle in Patients with Endometriomawith or without Deep Infiltrating Endometriosis

Genomic DNA damage in mouse transgenesis.

Creating transgenic mammals is currently a very inefficient process. In addition to problems with transgene integration and unpredictable expression patterns of the inserted gene, embryo loss occurs at various developmental stages. In the present study, we demonstrate that this loss is due to chromosomal damage. We examined the integrity of chromosomes in embryos produced by microinjection of p...

The Outcomes of Intracytoplasmic Sperm Injection and Laser Assisted Hatching in Women Undergoing In Vitro Fertilization Are Affected by The Cause of Infertility

Background We sought to determine the association between factors that affected clinical pregnancy and live birth rates in patients who underwent in vitro fertilization (IVF) and received intracytoplasmic sperm injection (ICSI) and/or laser assisted hatching (LAH), or neither. MaterialsAndMethods In this retrospective cohort study, the records of women who underwent IVF with or without ICSI and...

P-50: Elongating and Elongated Spermatids Manufactured In Vitro from Non-Human Primate Pluripotent Stem Cells

Background: We have recently shown that human embryonic (hESCs) and induced pluripotent stem cells (hiPSCs) can differentiate into advanced spermatogenic cells including round spermatids by in vitro culture (Easley et al., Direct differentiation of human pluripotent stem cells into haploid spermatogenic cells. Cell Reports 2, 440-446 2012) and also, in collaboration, that rhesus spermatogonial ...

Effects of Various Activators on Bovine Embryonic Development Following Intracytoplasmic Sperm Injection

The objective of this study was to compare the effectiveness of various combination activators of bovine oocyte following intracytoplasmic sperm injection (ICSI) in terms of cleavage and embryo development. Bovine ICSI oocytes were treated with a variation of treatments of combined or single activators as follows; 30 V for 15 x 2 μsec of electrical pulse +10 μg/mL cycloheximide (CHX),7% ethanol...
