View clinical trials related to Infertility, Male.
Filter by:Male from infertile couples are tested for semen analysis and sperm DNA fragmentation. Any case with high DNA fragmentation index (DFI) will be randomized indicated for multi-micro nutrient supplement (PROfortil™) in 3 months and then checked again post-treatment for (DFI). The IVF/ICSI cycles will be analyzed for pregnancy outcomes
This is a RCT to test the outcome of two protocols used for preparation of the endometrium for frozen blastocyst embryo transfer
Comparing second ejaculate and physiological ICSI (PICSI) as strategies for improvement of abnormal sperm DNA fragmentation in patients undergoing ICSI.
Comparing the reproductive outcomes of different sperm selection techniques; Density gradient centrifugation (DGC), Testicular sperm (Testi), Physiological ICSI (PICSI), and Magnetic activated cell sorting (MACS) in abnormal sperm DNA fragmentation (SDF) ICSI patients.
Spermatogonial stem cell transplantation through ultrasound guided rete testis injection and testicular tissue grafting will be performed for participants who have frozen testicular tissue prior to gonadotoxic therapy. The purpose of this study is to test the safety and feasibility of these transplant technologies and restore fertility for these participants.
Study rationale 1. An increasing proportion of the worldwide population is being infected with COVID-19. 2. There are ongoing and currently unanswered safety concerns about the effects of COVID-19 on reproductive health. 3. It will be immensely reassuring to rapidly report that COVID-19 has no detectable effects on male endocrine or sperm function. Conversely, if COVID-19 does impair male reproductive health, appropriate screening can be performed in couples trying to conceive, and further research can be undertaken. 4. The proposed study will be simple, rapid, and authoritative for the UK and worldwide.
The purpose of this research study is to evaluate if special types of cells called round spermatids can be gathered from men with non-obstructive azoospermia and used (in absence of elongated spermatids and spermatozoa) to reliably and effectively create pregnancy with a procedure called Round Spermatid Injection (ROSI). This process is similar to In Vitro Fertilization, or 'IVF'. In addition, this study wants to test the safety of ROSI and see what effects (good and bad) it has on embryo created from this method.
To evaluate the influence of lead (pb) and cadmium (cd) seminal plasma level on embryo development and pregnancy rate during intracytoplasmic sperm injection (ICSI).
Very little is known about how medical providers can help adolescent and young adults (AYAs) and their caregivers make decisions about fertility preservation (sperm banking) before beginning cancer treatment. The purpose of this study is to see if having a guided conversation about fertility preservation increases preservation rates and/or satisfaction with the decision among AYA males with cancer. The primary hypothesis is that compared to standard of care control group (routine fertility consult at diagnosis, n=20), AYAs in the intervention arm (routine fertility consult at diagnosis + FP Decision Tool and Facilitated Conversation by trained interventionist) will have higher rates of FP uptake. The secondary hypothesis is that families in the intervention group will report better FP decision quality compared to those in the control arm.
A total of 60 men (40 with a history of infertility and treatment with assisted reproduction and 20 infertile controls achieving conception naturally) will be asked to provide at least one semen sample each for conventional semen analysis including measurement of DNA-fragmentation and semen preparation with swim-up. The prepared semen sample will then analyzed by comprehensive microscopy analyses aiming at identifying distinct subpopulations of spermatozoa based on chromatin density and composition, mitochondrial and acrosome function and epigenetic markers. In addition, spermatozoa samples of selected individuals will be subjected to comprehensive analyses of the chromatin and RNA expression status using epigenomic approaches.
