Filter by:This study aims to better understand the effects of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, virus that causes the coronavirus disease 2019 (COVID-19), on male fertility.
The purpose of this study is to compare semen parameters with in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) when male factor infertility patients abstain from ejaculation more than 48 hours (routine care) or less than 24 hours from the day of the partner's oocyte retrieval. The investigators hypothesize that total motile sperm count will be improved with ejaculatory abstinence (EA) less than 24 hours. Information from this trial could allow investigators to optimize chances for a successful pregnancy in patients who need IVF/ICSI.
To evaluate embryology outcomes after application of a technique known as round spermatid injection (ROSI) into donor oocytes in a high-volume clinical infertility practice.
The aim of the study is to examine the value of the new MRI techniques (spectroscopy and DWI), and FDG-PET in prognostication of male infertility.
Single center, prospective, open clinical study to determine the genomic imprint (epigenetic modification) in a series of male infertility patients with alterations in their spermiogram (oligozoospermia) compared to a group of fertile patients in order to evaluate the effect of FSH ( follicle stimulating hormone) administration on these modifications and on male infertility.
In this study, investigators assess, using Fluorescence in situ Hybridization (FISH) and Comparative Genomic Hybridization (CGH) arrays for Preimplantation Genetic Screening (PGS), the incidence of aneuploidies in spermatozoa and embryos from infertile men with and without microdeletions who undergo assisted reproduction in their clinics.
There is a lack of clarity regarding the justification to instruct the couple to shift from intracytoplasmic sperm injection (ICSI) to intracytoplasmic morphologically selected sperm injection (IMSI). In this study, we aim at evaluating the efficacy of IMSI in couples with previous implantation failure with ICSI.
Hypothesis: To identify new gene mutations that can be related to patients with idiopathic male factor infertility. Primary Objective: To detect possible genetic abnormalities in families with more than one sibling with male infertility. Secondary Objective: To evaluate using next generation DNA sequencing in cases of infertility
A varicocele is the presence of dilated testicular veins in the scrotum. Although it is generally agreed that a varicocele is the most common identifiable pathology in infertile men (detected in up to 40% of men in some series of men with infertility), the influence of a varicocele on male fertility potential and role of varicocelectomy in restoring of fertility remain the subject of ongoing controversy. The present controversy on the effect of varicocelectomy on male fertility potential has led many clinicians to dismiss the diagnosis of a varicocele altogether and instead, offer alternative treatments to the couple. Many of these alternative therapies are expensive and risky for the patients and their children. Several recent reviews have critically examined the results of randomized, controlled trials of varicocelectomy on fertility potential. The effect of varicocelectomy on spontaneous pregnancy rates remains controversial. The investigators hypothesize that a varicocelectomy will result in a significant improvement in fertility and testicular function in infertile men with a clinical varicocele.
