In order to study the impact of procedures of IVF/ICSI technology on sex ratio in China, we conducted this multi-center retrospective study including 121,247 babies born to 93,895 women in China. There were 62,700 male babies and 58,477 female babies, making the sex ratio being 51.8% (Male: Female = 107:100). In univariate logistic regression analysis, sex ratio was imbalance toward females of...
BACKGROUND Since its introduction in 1994, testicular stem cell transplantation (TSCT) has been widely used for research. This technique may also become important for preserving fertility in pre-pubertal cancer patients. Therefore, it is necessary to investigate the safety aspects of reproduction using spermatozoa obtained after TSCT. In this study, preimplantation development of mouse embryos,...
IMPORTANCE Between 1978 and 2010, approximately 5 million infants were born after in vitro fertilization (IVF) treatments. Yet limited information on neurodevelopment after IVF exists, especially after the first year of life. OBJECTIVE To examine the association between use of any IVF and different IVF procedures and the risk of autistic disorder and mental retardation in the offspring. DES...
The objective of this study was to assess fertilization, implantation and pregnancy rates in infertile patients with severe teratozoospermia [P (poor prognosis) pattern sperm morphology assessed by strict criteria] treated by in-vitro fertilization (IVF) using a high insemination concentration (HIC), or by intracytoplasmic sperm injection (ICSI). This was a retrospective cohort study performed ...
The study's objective was to assess the effect of a cognitive behavioral group intervention on the pregnancy rates of patients submitted to in vitro fertilization (IVF) techniques or to intracytoplasmic sperm injection (ICSI). The study was conducted on 188 patients, 93 who participated in a group of psychological intervention before the IVF and ICSI procedures and 95 patients submitted to IVF ...
OBJECTIVE To compare prelabour caesarean section (CS) rates in older nulliparous women with a term singleton baby in cephalic presentation conceiving spontaneously and through IVF/ICSI. When the latter women would ask for CS, how willing are gynaecologists to comply with that request? METHODS A population-based retrospective (1995-2009) cohort study, conducted in Northern Belgium. A compariso...
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 Anti-nuclear antibodies (ANA) are suspected of having relevance to adverse reproductive events. METHODS This study aims to investigate the potential effect of ANA on IVF/ICSI outcome and the therapeutic role of prednisone plus low-dose aspirin (P + A) adjuvant treatment in ANA + patients. The first IVF/ICSI cycles without P + A of sixty-six ANA + women were enrolled as the ANA + gr...
Great advances have been made in the field of assisted reproductive technology (ART) since the first in vitro fertilization (IVF) baby was born in Korea in the year of 1985. However, it deserve to say that the invaluable data from fertility centers may serve as a useful source to find out which factors affect successful IVF outcome and to offer applicable information to infertile patients and f...
BACKGROUND Implantation remains a limiting step in IVF/ICSI. Endometrial injury isa promising procedure aiming at improving the implantation and pregnancy rates after IVF/ICSI. OBJECTIVE The aim of this study was to evaluate the effect of endometrial injury induced in precedingcycle on IVF/ICSI outcome. MATERIALS AND METHODS Four hundred patients undergoing their first IVF/ICSI cycle in two...
