The existence of a complex population of mRNA in human sperm is well documented but their role is not yet elucidated. Using discontinuous density gradients, we have isolated high and low motile sperm from the same semen sample. The levels of different transcripts coding for molecules either involved in nuclear condensation (protamines 1 and 2) or in(More)
To investigate the risk of transmission of hepatitis C virus (HCV) via semen in assisted reproduction techniques, semen samples from 32 men chronically infected with HCV attending a center for assisted procreation were tested for HCV RNA by a reverse transcription-PCR protocol by using a modified version of the Cobas AMPLICOR HCV assay (version 2.0; Roche(More)
Medical assistance for procreation in a couple where one or both parents has hepatitis C viral infection (HCV) raises the issue of the transmission of the infection to the baby and/or of possible contamination of both the technicians and the gametes or embryos from virus-free parents in the laboratory. It becomes essential to assess transmission risk in(More)
OBJECTIVE To evaluate genetic, demographic and clinical features in patients with cryopyrin-associated periodic syndrome (CAPS) from the Eurofever Registry, with a focus on genotype-phenotype correlations and predictive disease severity markers. METHODS A web-based registry retrospectively collected data on patients with CAPS. Experts in the disease(More)
OBJECTIVE To determine the incidence of cytomegalovirus in the ejaculates of infertile men who were seropositive for IgG antibodies to cytomegalovirus. DESIGN Prospective study. PATIENT(S) We tested cytomegalovirus infection in the semen of men participating in an IVF-ET program. MAIN OUTCOME MEASURE(S) IgG and IgM antibodies to cytomegalovirus were(More)
In France, assisted reproductive technology (ART) for hepatitis C virus (HCV)-infected patients is now subject to strict control after the publication of recent guidelines. Infertile serodiscordant couples (HCV-viraemic men and their seronegative female partners) require special care to carried out in designated 'viral risk' laboratories. Twelve sequential(More)
BACKGROUND The global obesity epidemic has paralleled a decrease in semen quality. Yet, the association between obesity and sperm parameters remains controversial. The purpose of this report was to update the evidence on the association between BMI and sperm count through a systematic review with meta-analysis. METHODS A systematic review of available(More)
BACKGROUND Cryopreservation/thawing of bovine spermatozoa induces a reduction in cell viability and is possibly associated with a form of programmed cell death that we previously named 'apoptosis-like phenomenon'. METHODS In this study, we specified, by flow cytometry, the moment of appearance of some characteristics of apoptosis during the(More)
BACKGROUND The guidelines advise arterial embolization in case of post-partum hemorrhage. We evaluated its feasibility and the subsequent fertility. METHODS A retrospective study has been conducted in our center for the past 10 years (1996-2005). Fifty-two patients experiencing a primary post-partum hemorrhage who were resistant to medical treatment(More)
We here report a successful pregnancy and healthy childbirth obtained in a case of total globozoospermia after intracytoplasmic morphologically selected sperm injection (IMSI) without assisted oocyte activation (AOA). Two semen analyses showed 100% globozoospermia on classic spermocytogram. Motile sperm organelle morphology examination (MSOME) analysis at(More)
