Intensified peroxidation in the Graafian follicle may be a factor compromising the normal development of the oocyte. The aim of this study was to measure concentrations of three oxidative stress markers: conjugated dienes, lipid hydroperoxides and thiobarbituric acid-reactive substances, in preovulatory follicular fluids and sera of 145 women attending an(More)
Endometriosis is a common disease in women at reproductive age. We investigated the concentration of neutrophil-activating factor (growth-regulated gene-alpha; GRO-alpha) (a member of the chemokine family), in peritoneal fluid of infertile women with or without endometriosis. Peritoneal fluid was obtained laparoscopically from 22 women with and 21 without(More)
BACKGROUND The effect of recombinant human LH (r-hLH; lutropin alfa) in women undergoing controlled ovarian stimulation with recombinant human FSH (r-hFSH) prior to IVF was investigated. METHODS After down-regulation with the GnRH agonist, buserelin, 114 normo-ovulatory women (aged 18-37 years) received r-hFSH alone until the lead follicle reached a(More)
Cystic fibrosis (CF) is one of the autosomal recessive diseases, caused by mutations in a gene known as cystic fibrosis transmembrane regulator (CFTR). The majority of adult males with CF (99%) is characterized by congenital bilateral absence of vas deferens (CBAVD). CBAVD is encountered in 1-2% of infertile males without CF. Females with CF are found to be(More)
BACKGROUND The overall aim of this prospective, randomized study was to compare the reproductive potential of fresh and frozen-thawed ejaculated spermatozoa from oligoasthenoteratozoospermic patients in an intracytoplasmic sperm injection (ICSI) procedure. METHODS All patients consenting to participate in this study had a sperm sample frozen prior to the(More)
BACKGROUND Failed fertilization after IVF occurs in 10-20% of cycles. Conflicting results of rescue fertilization by ICSI have been reported. We therefore compared the success rate in terms of fertilization and pregnancy of cycles in which rescue ICSI was performed with those from a matched control group of primarily ICSI cycles. METHODS Unfertilized(More)
The aim of this study was to assess the benefits of the transfer of only two of the best quality embryos, three if a woman was over 35 years of age, in terms of pregnancy rate and the incidence of multiple gestations. In 1993-94, when we were replacing three embryos when available and up to five when the woman was over 35 years of age, 217 clinical(More)
OBJECTIVE To examine the nonenzymatic antioxidant properties of human seminal plasma. DESIGN Determination of total (peroxyl) radical-trapping antioxidant parameter and malondialdehyde concentration in seminal plasma of 112 men attending IVF-ET or intracytoplasmic sperm injection (ICSI) programs. SETTING University-based center for reproductive(More)
Uterine leiomyomata (fibroids) are very common, mostly benign tumors in women of reproductive age. Symptomatic fibroids cause significant morbidity and are characterized by heavy prolonged menstrual bleeding, by pain and pelvic pressure and, in some cases, they may lead to reproductive dysfunctions. Up to date, surgical procedures (hysterectomy or(More)
