Live birth after SrCl(2) oocyte activation in previous repeated failed or low fertilization rates after ICSI of frozen-thawed testicular spermatozoa: case report.

Purpose: To report a live birth resulting after strontium chloride (SrCl(2)) oocyte activation in a couple with complete fertilization failure or low fertilization rates following intracytoplasmic sperm injection (ICSI) of frozen-thawed testicular spermatozoa.

Methods: The couple underwent ICSI of frozen-thawed testicular spermatozoa. After ICSI, the oocytes were artificially activated by SrCl(2) because the results of fertilization were not satisfactory in the previous cycles.
