<p>Device (10, 110) for separating motile sperm from a sample (100, 200), comprising a vessel (15, 115) having an inlet port (20, 120), an outlet port (35, 135) which is initially closed, a medium (40, 140) into which motile sperm in the sample (100, 200) can migrate into the vessel (15, 115) via the inlet (20, 120), and an actuator (50, 150), the operation of which opens the outlet (35, 135), thereby allowing the medium (40, 140) to flow out of the vessel (15, 115) through the outlet (35, 135). The medium (40, 140) in the vessel (15, 115) is initially prevented from flowing through the outlet (35, 135), thus allowing an incubation period which allows motile sperm sufficient time to migrate from the sample (100, 200) into the medium (40, 140) before the medium (40, 140) leaves the vessel (35, 135). The device (10, 110) preferably comprises spermatozoa detection means in communication with the outlet. In devices for separating sperm, capillary flow takes place through non-fibrous material, such as the space between sheets (81a and 81b; 181a and 181b) of closely-juxtaposed material. A device for separating motile and non-motile sperm includes a temperature sensor, a heat source (70, 170) and, optionally, temperature regulation means.</p> |
