Moderate ovarian stimulation does not increase the incidence of human embryo chromosomal abnormalities in in vitro fertilization cycles.

2012

A high chromosomal abnormalities rate has been observed in human embryos derived from in vitro fertilization (IVF) treatments. The real incidence in natural cycles has been poorly studied, so whether this frequency may be induced by external factors, such as use of gonadotropins for ovarian stimulation, remains unknown.We conducted a prospective cohort study in a University-affiliated private infertility clinic with a comparison between unstimulated and stimulated ovarian cycles in the same women. Preimplantation genetic screening by fluorescence in situ hybridization was performed in all viable d 3 embryos.The primary objective was to compare the incidence of embryo chromosomal abnormaliti…

Fertility Relevance Probability Analysis Shortlists Genetic Markers for Male Fertility Impairment.

2020

Impairment of male fertility is one of the major public health issues worldwide. Nevertheless, genetic causes of male sub- and infertility can often only be suspected due to the lack of reliable and easy-to-use routine tests. Yet, the development of a marker panel is complicated by the large quantity of potentially predictive markers. Actually, hundreds or even thousands of genes could have fertility relevance. Thus, a systematic method enabling a selection of the most predictive markers out of the many candidates is required. As a criterion for marker selection, we derived a gene-specific score, which we refer to as fertility relevance probability (FRP). For this purpose, we first categori…

Live Birth After Uterus Transplantation

2015

ABSTRACTIn the 3 decades since the birth of the first in vitro fertilization baby in 1978, there have been remarkable advances in infertility treatment. Until now, however, absolute uterine factor infertility remained the only major type of female infertility viewed as untreatable. Absolute uterine

The gender gap in the diagnostic-therapeutic journey of the infertile couple

2021

Medical procreation impairs both the biological and psychological lives of couples. However, male and female attitudes to infertility are different and require a different approach during the IVF journey. Thus, the gender impact assessment (GIA) method was used to analyse original studies present in the literature. We found some gender-related differences and, subsequently, possible outcomes of intervention to improve healthy reproduction management and prevent infertility. In particular, it became apparent that there was the need for an in-depth male infertility assessment and a gender-specific follow-up.

Microarray analysis in sperm from fertile and infertile men without basic sperm analysis abnormalities reveals a significantly different transcriptom…

2007

Sperm analysis following World Health Organization guidelines is unable to explain the molecular causes of male infertility when basic sperm parameters are within a normal range and women do not present gynecologic pathology. Consequently, there is a need for accurate diagnostic tools in this area, and microarray technology emerges as promising. We present, for the first time, preliminary results of a comparison of sperm mRNA expression profiles between fertile and infertile men with normal semen parameters, discovering profound discrepancies between groups, with potential diagnostic and therapeutic possibilities.

Cellular therapies for the endometrium: An update

2018

An update on the current state of endometrial cell therapies in terms of cell types, mechanisms of action, delivery, safety, regulatory frameworks and future perspectives. This review focuses on clinical trials using angiogenesis-promoting therapies and stromal therapies piloted in the last 10 years for alleviating Asherman's syndrome and long-term infertility. All studies present promising preliminary results, indicating increased endometrial thickness and resumed menstruation. Further characterization of individual cell products, their mode of action and larger clinical trials will be essential to establishing cell therapy as a viable option for the treatment of infertility and fertility …

Human uterus transplantation in focus.

2016

Introduction Uterus transplantation (UTx) is introduced as the first treatment for absolute uterine factor infertility (AUFI), affecting 1:500 fertile aged women. This review presents potential patients, research and human UTx cases. Sources of data Published articles and our research experience. Areas of agreement The first UTx live births in 2014 established UTx as a possible treatment for AUFI. This was proceeded by 15 years of systematic research. Areas of controversy Is a deceased donor UTx as effective as the proven successful live donor UTx?. Growing points Human UTx trials will accumulate data on risks, effectiveness and long-term consequences for donors, recipients and children. Th…

The history behind successful uterine transplantation in humans

2017

This paper aimed to describe the basic aspects of uterine transplant (UTx) research in humans, including preliminary experiences in rodents and domestic species. Studies in rats, domestic species, and non-human primates validated and optimized the UTx procedure in terms of its surgical aspects, immunosuppression, rejection diagnosis, peculiarities of pregnancy in immunosuppressed patients, and patients with special uterine conditions. In animal species, the first live birth from UTx was achieved in a syngeneic mouse model in 2003. Twenty-five UTx procedures have been performed in humans. The first two cases were unsuccessful, but established the need for rigorous research to improve success…

Deficiencies in reporting results of lesbians and gays after donor intrauterine insemination and assisted reproductive technology treatments: a revie…

2015

At a time when increasing numbers of lesbians and gays consider parenthood using reproductive assistance in infertility centers, the present review aims to summarize the results obtained so far by lesbians after intrauterine insemination (IUI) and in-vitro fertilization (IVF) using donor spermatozoa (D-IUI and D-IVF, respectively) and gays entering into gestational-surrogacy programs. Data show that gays display normal semen parameters and lesbians exhibit no specific causes of female infertility except perhaps for polycystic ovary syndrome (PCOS) and some PCOS-related factors. Pair-bonded lesbians entering into D-IUI programs, tend to have higher pregnancy and delivery percentages followin…
