Background: The aim of this study was to determine the outcome of IVF/ ICSI by modification of embryo transfer technique following embryo transfer. Materials and Methods: In this randomized trial study, two groups of infertile women (n = 55) aged %40 years underwent in vitro fertilization or intracytoplasmic sperm injection treatment cycles with or without 0.2 mL of air pushed into the catheter...

One explanation for why downstream gonadotropin protocol changes during IVF commonly arrive too late to have significant effects is that embryo development actually begins during oogenesis. Thus, efforts to modify the chromosomal status of blastocysts must address the ovarian milieu well in advance of follicular recruitment. A 42 years old woman with primary infertility of 3 years duration atte...

Ovarian pregnancy (OP) after embryo transfer is very rare. Due to the rarity and the asymptomatic nature, there are still difficulties in diagnosis and treatment. The traditional operative treatment for OP has been oophorectomy. However, the desire to maintain reproductive capability and improvements in laparoscopy have more recently led to conservative laparoscopic techniques. This rare compli...

BACKGROUND Multiple births are associated with serious adverse infant and maternal outcomes. The objective of this study was to assess the multiple-birth risk (MBR) associated with IVF and determine whether the risk is impacted by stage of embryo development at transfer. METHODS A population-based sample of 50 819 IVF transfers utilizing day 3 or day 5 embryos performed in the USA in 2001 on ...
