The aim of this study was to determine if a low response to gonadotrophin stimulation could be considered as an indication for intracytoplasmic sperm injection (ICSI). This prospective study included a total of 96 non-male infertile couples with six or fewer retrieved oocytes, who underwent 104 in-vitro fertilization (IVF) cycles between January 1996 and April 1997. They were randomly divided i...

Considerable changes are afoot in the practice of assisted human conception. Doubts about its methods, especially over endocrinology, concern its complexity and its expense. IVF has spread worldwide since its beginnings in the UK, but its current practice, termed routine IVF, is being challenged by simpler routines. These include natural cycle IVF, which has been in the background for many year...

This is a report of a case of an egg recovery procedure completed with manual suction instead of the automated negative pressure suction. A 35-year-old woman who was undergoing in vitro fertilization (IVF) treatment had to undergo oocyte recovery using manual suction through a syringe instead of the automated negative pressure suction systems because of the failure of both the initial and repla...

OBJECTIVE The aim of this study was to explore the effects of the insemination method on the outcomes of elective blastocyst culture. METHODS We retrospectively analyzed the outcomes of elective blastocyst culture performed between January 2011 and December 2014. RESULTS There were 2,003 cycles of conventional in vitro fertilization (IVF) and 336 cycles of intracytoplasmic sperm injection (...

OBJECTIVE To investigate the impact of Hepatitis C Virus (HCV) infection on in vitro fertilization (IVF) outcomes. METHODS A retrospective analysis was conducted using IVF cases occurring at the Centre for Reproductive Medicine, General Hospital of Tianjin Medical University between January 2008 and December 2013. A total of 1424 couples undergoing IVF cycles were included: Ninety couples whe...

Meta-analyses have found conflicting results with respect to the use of progesterone or progesterone plus estrogen as luteal phase support for in vitro fertilization (IVF) protocols involving gonadotropins and/or gonadotropin-releasing hormone analogs. The aim of the present study was to perform an updated meta-analysis on the efficacy of progesterone versus progesterone plus estrogen as luteal...

Intracytoplasmic sperm injection (ICSI), an important method used to treat male subfertility, is applied in the transgenic technology of sperm-mediated gene transfer. However, no study has described successful generation of offspring using ICSI in the common marmoset, a small non-human primate used as a model for biomedical translational research. In this study, we investigated blastocyst devel...

BACKGROUND Growth hormone (GH) is used as an adjuvant therapy in in vitro fertilization and embryo transfer (IVF-ET) for poor ovarian responders, but findings for its effects on outcomes of IVF have been conflicting. The aim of the study was to compare IVF-ET outcomes among women with poor ovarian responders, and find which subgroup can benefit from the GH addition. METHODS We searched the da...
