In 100 consecutive patients who were undergoing laparoscopy for infertility (group 1, n = 52), chronic pelvic pain 2, 18) or tubal sterilization 3, 30, asymptomatic fertile women), peritoneal biopsies taken from areas of visually normal peritoneum uterosacral ligaments. Twenty-six in group 1 (50%), eight 2 (44.4%) and 13 3 (43.3%), found to have laparoscopic evidence endometriosis elsewhere the pelvis. The majority women (80.7% 87.5% 100% 3) had stage I disease. incidence distinctive...

BACKGROUND: Anti-Müllerian hormone (AMH) has been recently proposed as a marker for ovarian ageing and poor response to controlled hyperstimulation in assisted reproduction cycles. The present study was undertaken investigate the usefulness of baseline cycle day 3 AMH levels serum concentrations obtained on fifth gonadotropin therapy predicting pregnancy women undergoing stimulation with FSH under pituitary desensitization reproduction. METHODS: A total 80 their first IVF/intracytoplasmic...

Assisted reproductive technologies (ARTs) have been shown to be associated with general vascular dysfunction in late childhood. However, it is unknown whether cardiac remodeling also present and if these changes already manifest prenatal life. Our aim was assess fetal infant (6 months of age) cardiovascular function ART pregnancies.This prospective cohort study included 100 fetuses conceived by control pregnancies. showed signs remodeling, including a more globular heart thicker myocardial...

Throughout the primary literature and within textbooks, erythrocyte has been tacitly accepted to have maintained a unique physiological role; namely gas transport exchange. In non-mammalian vertebrates, nucleated erythrocytes are present in circulation throughout life cycle fragmented series of observations mammals support potential role non-respiratory biological processes. We hypothesised that could actively participate via ligand-induced transcriptional re-programming immune...

The transplantation of ovarian tissue has recently been the focus intense investigation with aim avoiding premature failure mainly in patients receiving chemotherapy or radiotherapy for malignant disease. Here, we present an evaluation long-term function both fresh (patients 1, 2, and 3) cryopreserved (patient 4) autografts four premenopausal aged 46–49 yr who underwent heterotopic were followed over a 1-yr period without gonadotropins to stimulate follicular growth. In 1 ∼1 cm3 cortical...

To evaluate the relative importance of follicle stimulating hormone (FSH) and luteinizing (LH) in follicular development oocyte fertility human species, use recombinant FSH, menopausal gonadotrophin (HMG), very highly purified urinary FSH (FSH-HP) plus oestradiol valerate for ovarian stimulation in-vitro fertilization (IVF) were compared three cycles a woman with isolated congenital deficiency who had never been treated agents. The total number ampoules gonadotrophins used was lower HMG...

It has been recently suggested that gonadotrophin-releasing hormone agonist down-regulation in some normogonadotrophic women may result profound suppression of LH concentrations, impairing adequate oestradiol synthesis and IVF pregnancy outcome. The aims this study, where receiver-operating characteristic (ROC) analysis was used, were: (i) to assess the usefulness serum measurement on stimulation day 7 (S7) as a predictor ovarian response, outcome, implantation, outcome patients treated with...

Studies in macaques have indicated that androgens some synergistic effects with FSH on folliculogenesis. This study investigated the usefulness of pretreatment transdermal testosterone low-responder IVF patients.Randomized clinical trial including 62 infertile women who had a background first treatment cycle cancelled because poor follicular response. Patients were randomized two groups their second attempt. In patients Group 1 (n = 31), application preceding standard gonadotrophin ovarian...

BACKGROUND: High-order multiple pregnancies (triplets or more) have a large adverse impact on perinatal morbidity and mortality as well important economic consequences. Most triplets higher births are due to ovulation induction alone in combination with intrauterine insemination (IUI) rather than in-vitro fertilization (IVF). The present investigation was undertaken determine whether there were specific variables that related patient clinical characteristics (age of the woman, duration...

Is there any effect of maternal age on chromosomal anomaly rate and spectrum in recurrent miscarriage?There was no significant difference the chromosome abnormality between sporadic miscarriage but increased significantly with age.About 50-70% non-recurrent miscarriages occur because a anomaly, agreement about either or number previous has been reached.A retrospective cohort 353 successfully karyotyped same center 2002 2011, grouped according to age.Among women, 153 were below 35 years (73...
