Fertilizing ability of sperm with unexplained in vitro fertilization failures as assessed by the zona-free hamster egg penetration assay: its prognostic value for sperm-oolemma interaction

Assessment Of Sperm Quality Analyzer Ii B: Comparison With Manual Semen Analysis And Casa

“…There are some available sperm function tests including sperm penetration test, Acrobeads test, and hypoosmotic swelling test [3,5,11]. Accurate determination of the motion characteristics of spermatozoa is also important for the diagnosis of male factor infertility.…”

Evaluation of the Sperm Motility Analyzer System (SMAS) for the Assessment of Sperm Quality in Infertile Men

“…Although the WHO [1999] standardized the laboratory procedures involved in assessing human semen, the fundamental problem remains that the conventional criteria of semen quality are of limited prognostic value in predicting pregnancy rate [Aitken et al 1985;Bostofte et al 1990]. There are various available sperm function tests, including the Acrobeads test, hypoosmotic swelling test, and the hemizona assay [Wolf et al 1996;Jeyendran et al 1984;Morshedi et al 1995]. Accurate determination of the motion characteristics of spermatozoa is also important for the diagnosis of male factor infertility, but standard manual semen analysis is a rather subjective technique associated with large inter-laboratory variation.…”

Role of sperm DNA integrity in fertility

“…The sperm parameters concentration, motility and morphology are, however, claimed to be poor predictors of a male´s fertility status, this in natural conception Guzick et al, 2001) as well as in assisted reproductive techniques (ART) (Wolf et al, 1996).…”
