9 Clinical Trials for Various Conditions
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.
The purpose of this study is to understand the experience of men and their partners when diagnosed with male-factor infertility while trying to achieve a pregnancy and the skills they use to adapt to this diagnosis.
Purpose/Lay Summary: Background: - Chromosomes are the structures inside of each cell that carry our genetic material (genes). Certain differences in the sex chromosomes are known to cause various diseases, such as infertility, Turner syndrome, or Klinefelter syndrome. However, it is not fully understood why these differences are seen and what clinical findings may be caused with different sex chromosome variants. This study is seeking to learn more about the genetic and clinical characteristics of disorders related to the X and Y chromosomes. Objectives: - To study related medical conditions in people with sex chromosome variants. Eligibility: * Patients with known sex chromosome differences may be eligible to participate. * Healthy volunteers age 18 - 55 Design: * Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. * This study will last about 5 days. Participants will have a variety of endocrine and other tests. They will provide blood, urine, and semen samples for these tests. * Imaging studies of the heart and abdomen will be performed. These tests may include ultrasounds and magnetic resonance imaging. * Participants will also have their vision and hearing checked. * Healthy volunteers with have a single day visit for a medical history, physical exam, and blood and skin samples. * Treatment will not be provided as part of this study. * Compensation is offered.
The purpose of this study is to determine if using microdots of hyaluronan (PICSI) to select sperm for ICSI will result in increased pregnancies especially with men that have a low hyaluronan binding score (HBA).
The purpose of this prospective, randomized study, was to determine if neck and shoulder massage performed within 15 minutes of semen sample collection will increase the semen volume, and therefore increase the total motile sperm available for insemination as a result of decreased stress.
Methods of infertility treatment may involve in vitro fertilization or IVF. Though effective, IVF is complex and expensive. Methods using no gonadotropin hormone stimulation of the ovaries are being compared to mild stimulation doses. The goal of the research is to determine which of these if more suitable as a low cost approach for varying individual patients.
The purpose of this study is to determine the effectiveness of the ViaCell's product media for freezing and thawing human eggs for future use in assisted reproductive technology.
Brief Summary: The objectives of the trial are to evaluate the safety and effectiveness of the FemaSeed Localized Directional Insemination for artificial insemination, now known as the FemaSeed Intratubal Insemination since FDA Cleared under K231730 in September 2023.
The purpose of this study is to demonstrate that the Eeva™ System is compatible with the Eeva 12-well Dish.
