Feeling weakness after ejaculation — is it harmful?

Sperm DNA fragmentation testing measures damage to the genetic material inside sperm, which standard semen analysis does not assess. A sample can have normal count, motility and morphology while carrying significant DNA damage. Where it may be informative: recurrent pregnancy loss, repeated IVF or ICSI failure, unexplained infertility with normal conventional parameters, and where there is a varicocele or significant lifestyle exposure. Where it is less useful: as a routine first-line test. It is not recommended for general screening, and an abnormal result does not always change management. Contributors to DNA damage include smoking, heat exposure, varicocele, infection, advanced age, obesity and oxidative stress. Several are modifiable, and repeating the test after three months of change is reasonable. Where fragmentation is high and does not improve, options include using surgically retrieved testicular sperm for ICSI, since testicular sperm typically shows less DNA damage than ejaculated sperm. Discuss with a urologist or andrologist whether it is likely to change anything in your situation before paying for it — that is the right question to ask of any add-on test.
