Freezing sperm as a way to protect quality as men age
Part of Women’s health & pregnancy clinical trials.
This study is looking at whether freezing sperm can protect the quality of sperm as men age. If you join, you'll provide samples for research, and the findings could help men plan for future fertility.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be a man between 18 and 65 years old.
- You must be having a semen analysis or fertility treatment at IVI Murcia.
- You must be willing to give a semen sample and a blood sample for this study.
- You cannot have been diagnosed with very low or no sperm count (below 1 million per mL).
- You cannot have a known chromosome problem or a missing piece of the Y chromosome.
- You cannot have had a fever in the last 3 months, have a varicocele, or be taking certain supplements for sperm health.

Other trials that look related to this one.
This study looks at how everyday chemicals called endocrine disruptors (found in some plastics and personal care products) might affect sperm health in men with low sperm counts. If you qualify, you may help researchers learn whether reducing exposure to these chemicals can improve fertility.
This study measures “free radicals” in sperm to see how lifestyle and the microbiota (gut/community of microbes) may relate to sperm health. You may be asked to provide a semen sample as part of standard fertility testing, unless certain health factors apply.
This study tests a new way of preparing sperm for in vitro fertilization (IVF) to see if it is safe. It may help couples who are already planning IVF with fresh sperm samples.
This trial studies how doctors collect and freeze a small piece of testicle tissue from boys to protect future fertility before treatments like chemotherapy or radiation. It may help families preserve options for having children later if testicular function is permanently affected.
This study tests whether adding platelet-rich plasma (PRP – a treatment made from your blood that may help healing) to donor sperm before freezing helps protect the sperm. You may qualify if you are a healthy man aged 18–35 with strong semen quality.
This study looks at how the father's age might affect the growth of embryos in the lab. It is for couples doing their first IVF cycle, planning to test embryos for genetic health before freezing them, and then transferring one healthy embryo.
