A kit (10) for testing male fertility comprises a vessel (12), a base unit (14), a liquid supply (16) containing liquid (18), and two filters (20,22). The first filter (20) is a sample separation filter (20) which forms a hindrance to transmission of spermatozoa. The second filter (22) of the kit is a spermatozoa detection filter (22) comprising a reagent for identifying spermatozoa. Activation of the kit is prevented until a transport medium, such as the liquid, fills a gap (24) allowing spermatozoa to transmit to a detection zone (26). The kit may be of one-piece construction and utilises a thin piece of filter material to separate motile from non-motile spermatozoa.

La présente invention concerne un kit (10) servant à tester la fertilité masculine, comprenant une enceinte (12), une unité de base (14), une source de liquide (16) contenant un liquide (18), et deux filtres (20, 22). Le premier filtre (20) est un filtre de séparation d'échantillons (20) qui empêche la transmission de spermatozoïdes. Le second filtre (22) du kit est un filtre de détection de spermatozoïdes (22) comprenant un réactif qui permet d'identifier les spermatozoïdes. On empêche l'activation de ce kit jusqu'à ce qu'un milieu de transport, tel que le liquide, remplisse un espace donné, (24) permettant alors aux spermatozoïdes de s'acheminer vers une zone de détection (26). En outre, ce kit peut être constitué d'une seule pièce, et il utilise une pièce fine de matière filtre pour séparer les spermatozoïdes mobiles des spermatozoïdes non mobiles.
