One of the main problems concerning IVF units is the need to decrease the occurrence of multiple pregnancies in their practice without affecting the overall success rate. Different embryological parameters concerning every step of the early embryo development are known to have some predictive value for implantation potential. In this prospective study, a(More)
BACKGROUND Assisted reproduction techniques can minimize the risk of infection and treat possible sterility associated with serodiscordant couples. METHODS We assessed the efficacy of these techniques in 57 couples in which at least one partner had human immunodeficiency virus (HIV-1) infection that was currently under control (47 men and 10 women). The(More)
We have developed a new allele-specific amplification method for the preimplantation genetic diagnosis (PGD) of spinal muscular atrophy (SMA; Werdnig-Hoffmann disease) from a single cell. This method is based on the detection of the deletion of exon 7 of the telomeric copy of the survival motor neurone (SMN(t)) gene. An oligonucleotide was designed to be(More)
BACKGROUND The aim of this prospective multicentre study was to compare the two endoscopic techniques of laparoscopy and fertiloscopy in routine evaluation of the pelvis in infertile women. METHODS A total of 92 women was selected in 14 University Hospitals to undergo fertiloscopy followed by transabdominal laparoscopy by a team of two surgeons in each(More)
OBJECTIVE To determine whether there is a difference between the known gestational age in pregnancies conceived after IVF and the estimated gestational age based on the crown-rump length (CRL) measurement during the first trimester. DESIGN We retrospectively (between 2007 and 2012) studied a cohort of 6,739 patients who underwent ultrasonography between(More)
OBJECTIVE To evaluate the efficiency of our treatment of vaginal infection for couples included in an IVF program. PATIENTS AND METHODS Microbiologic screening of vaginal flora and semen has been performed one month prior to in vitro fertilization for 951 couples in 2000. Antibiotic treatment was prescribed in case of positive culture. RESULTS Positive(More)
OBJECTIVE To determine the homocysteine evolution during ovarian stimulation in IVF or ICSI protocols and in, a second time, to evaluate the role of hyperhomocysteine as thrombotic risk factor for the treated patients. MATERIAL AND METHODS Plasma homocysteine was determined three times for each of 31 women included in an IVF/ICSI program. Dosages were(More)
OBJECTIVE We studied the impact of infertility and all the more Assisted Reproductive Techniques on marital relations and sexuality. MATERIAL AND METHOD Our study is based on a questionnaire distributed in our centre and on a review of literature. RESULTS Our inquest shows that both partners keep a good relationship in their couple and support each(More)
BACKGROUND We report the first attempts at preimplantation genetic diagnosis (PGD) and IVF and their accompanying difficulties for achondroplasia (ACH) patients. METHODS A PGD test was developed using fluorescent single cell PCR on lymphoblasts from patients and controls and from blastomeres from surplus IVF embryos. A specific digestion control based on(More)
