Comparison of ICSI Outcomes in Cycles Using Testicular and Ejaculate Sperm From Couples With High SDF
Spain22 participantsStarted 2020-10-01
Plain-language summary
In patients with oligospermia in the ejaculate or previous ICSI failures if it concurs with high DNA fragmentation, it has been hypothesized that the use of sperm obtained from the testicle would improve the clinical results, since a source of damage to the spermatic DNA is post-testicular in its storage in the epididymis and thus could be avoided. The clinical information available so far is low, of low quality and all the studies present certain limitations susceptible to improvements in further investigations before giving a definitive answer to patients in these circumstances, about whether they should opt for testicular biopsy or for the use of semen in the ejaculate.The intention proposed in our project, is to demonstrate whether using testicular sperm, compared to those available in an ejaculate in these cases, offers a clinically and statistically significant increase in chromosomally normal embryos available that may lead to better reproductive performance of the cycles, in a design never before done, where half of a patient's oocytes are inseminated from ejaculated sperm and the other half from sperm obtained in the testicular biopsy.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Infertile males with severe oligospermia (\<5 mill/ml of spermatozoa in the ejaculate) or infertile males without severe oligospermia (\>5 mill/ml of spermatozoa in the ejaculate) but with a previous complete ICSI failure. In addition, all of them have to have a sperm DNA fragmentation test level higher than 30% (SDF\>30%), the threshold value for considering the result as abnormal.
* Women with adequate ovarian reserve, understood as those with AMH values \>10pM, and Antral Follicular Count (AFC) \>10.
Exclusion Criteria:
* Abnormal karyotype (previously known).
* Microdeletions in the Y chromosome (previously known).
* Carriers of known cystic fibrosis gene mutations.
* Presence of varicocele.
* Female age \>38 years.
* Presence of uterine pathology that may condition reproductive outcomes (fibroids, uterine malformations).
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
