Organism Human Homo sapiens
Reference Van den Bergh, M., Emiliani, S., Biramane, J. et al. (1998) A first prospective study of the individual straight line velocity of the spermatozoon and its influences on the fertilization rate after intracytoplasmic sperm injection. Hum. Reprod. , 13, 3103–3107 abstractPubMed ID9853865
Method P.3104 left column 2nd paragraph: "To measure the individual velocity of the spermatozoon [investigators] connected to the Olympus IMT inverted microscope with Normarski optics, normally used for ICSI [intracytoplasmic sperm injection], a video camera and video tape recorder. A data box with timer was installed between the camera and video tape recorder. All measurements were performed at ×300 magnification and on a microscope with heated stage. Temperature was kept constant at 37°C as usually done during the ICSI procedure."
Comments Abstract: "The straight line velocity of 500 individual spermatozoa was measured immediately before their direct injection into the cytoplasm of 500 metaphase II oocytes. The straight line velocity (VSL) did not have a normal distribution (P < 0.01) and ranged between 0 and 35 microm/s."
