This study investigated the clinical outcomes of intracytoplasmic sperm injection using sperm obtained via microdissection testicular sperm extraction, specifically comparing fertilization, embryo quality, and pregnancy rates between motile and poorly motile sperm groups. The researchers analyzed data collected by multiple authors to determine if sperm motility significantly impacted these key reproductive metrics following the specialized extraction procedure. The results indicated that while both groups underwent the same assisted reproduction techniques, the specific impact of sperm motility on good embryo formation and subsequent pregnancy success was evaluated through detailed statistical assessment. The paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.

Supplementary Material

( a ) Fertilization rates between motile and poorly motile sperms. ( b ) Good embryo formation rates† between motile and poorly motile sperms. (†Calculated as the number of good embryos/the number of fertilized egg × 100%). When embryo quality was assessed 2 days post-oocyte collection, the good embryo group included those at 4-cell Grades 1–3, 5-cell Grade 1, and 6-cell Grade 1 stages; at 3 days postoocyte collection, 8-cell Grades 1–3, 9-cell Grades 1–3, and 10-cell Grade 1 stages; at 5 days postoocyte collection, =3BB blastocysts. ( c ) Pregnancy rates between motile and poorly motile sperms.
