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,...

BACKGROUND The aim of this study was to investigate whether a pre-incubation time between oocyte retrieval and insemination or injection had any effect on the success rate of IVF or intracytoplasmic sperm injection (ICSI). Based on previously published data, many laboratories retain a time interval of several hours between oocyte retrieval and insemination/injection. In our setting, inseminatio...

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...

OBJECTIVE To assess the relationship between the ethnicity of women and the clinical success of in vitro fertilisation (IVF) or intracytoplasmic sperm injection (ICSI) treatment. DESIGN Observational cohort study. SETTING Nottingham University Research and Treatment Unit in Reproduction (NURTURE), UK. SAMPLE A total of 1517 women, of which 1291 were white Europeans and 226 belonged to an ...

BACKGROUND To evaluate the impact of the association of endometrioma with or without deep infiltrating endometriosis (DIE) after a first intra cytoplasmic sperm injection- in vitro fertilization (ICSI-IVF) cycle on pregnancy rate. MATERIALS AND METHODS In this retrospective study, women with endometrioma who underwent a first ICSI-IVF cycle from January 2007 to June 2010 were reviewed for pre...

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...

background: c-reactive protein (crp) can be increased after hormonal stimulations. the changes of crp might affect the success of in-vitro fertilization (ivf). objective: the aim of this study was to determine the possible relationship between the serum crp level and outcome of controlled ovarian stimulation, and pregnancy rate in patients undergoing ivf or intra cytoplasmic sperm injection (ic...

OBJECTIVE To investigate the incidence of complications in the use of assisted reproductive technology in the management of infertile couples. DESIGN Retrospective study. SETTING The Egyptian IVF & ET Center, Maadi, Cairo, Egypt. PATIENT(S) Two thousand nine hundred twenty-four patients underwent IVF-ET or intracytoplasmic sperm injection (ICSI) in 3,500 cycles. INTERVENTION(S) IVF-ET, ...

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...

Objective: The aim of the study was to investigate the course and outcomes of twin pregnancies conceived by different methods of assisted reproduction (ART) compared to those conceived spontaneously. Methods: The study involved patients with twin pregnancies who delivered at the Ob/Gyn Clinic of the Clinical Center of Serbia over a period of three years. Patients were differentiated according t...
