Pe. Egbase et al., PREGNANCY RATES AFTER INTRACYTOPLASMIC SPERM INJECTION IN RELATION TOSPERM RECOVERY TECHNIQUES, Journal of assisted reproduction and genetics, 14(6), 1997, pp. 317-320
Purpose/Methods: Clinical outcome after intracytoplasmic sperm injecti
on (ICSI) was evaluated in relation to three techniques of sperm recov
ery, mini-Percoll, simple concentration, and centrifugation and washin
g. Results: Whereas fertilization and embryonic cleavage rates were si
milar in the three groups, the rates of implantation and clinical preg
nancy were statistically significantly higher following sperm recovery
by the techniques of mini-Percoll and centrifugation and washing.
