Summary
Testicular sperm extraction (TESE) can cause temporary inflammation and scarring. Waiting over six months between TESE procedures improves sperm retrieval success and minimizes risks like testicular devascularization.
Area of Science:
- Reproductive Medicine
- Surgical Urology
Background:
- Testicular sperm extraction (TESE) is a method for retrieving sperm for assisted reproduction.
- The long-term physiological impact of TESE on testicular function remains incompletely understood.
Purpose of the Study:
- To evaluate the physiological effects of TESE on testicular function.
- To assess the impact of TESE timing on repeat sperm retrieval success.
Main Methods:
- Physical examinations, serial scrotal sonography, and histological analyses were performed on 64 patients post-TESE.
- Success rates of repeat sperm retrieval attempts were evaluated based on the interval between procedures.
Main Results:
- Ultrasonographic abnormalities were observed in 82% of patients at 3 months post-TESE, resolving by 6 months with scarring.
- Two patients experienced impaired testicular blood flow, one with complete devascularization after multiple biopsies.
- Repeat TESE success was significantly higher (>6 months interval: 80%) compared to shorter intervals (<6 months: 25%).
Conclusions:
- Transient adverse physiological effects are common after TESE, typically resolving within six months.
- Permanent testicular devascularization is a potential complication, particularly with multiple biopsies.
- Employing open biopsy with optical magnification may reduce the risk of vascular injury during TESE.
