Description:	The study aimed to establish the most suitable osmolarity range of the hypoosmotic solution for testing the membrane integrity in raw semen of rams. Sodium citrate and fructose based solutions (S) with the following osmolarities (mOsm/L) were used: 50 (S1), 75 (S2), 100 (S3), 125 (S4), 150 (S5), 175 (S6), 200 (S7), 250 (S8), 290 (S9) and 300 mOsm/L (S10). Nine mature Santa Ines rams (21.5+0.5 months; 72.9+1.6 kg) had semen collected one month apart. After the hypoosmotic swelling test (HOST) the ejaculates were evaluated using a phase-contrast microscope. A total of 200 spermatozoa were counted and sperm cells were classified as spermatozoa with coiled tails (CD, %), strongly coiled tail (CFD, %) or non-coiled tails. According to CD, S1, S2, S3, S4, S5, S6 and S7 were superior to S8, S9 and S10 (P<0,05). According to CED, S2, S3, S4, S5, S6 and S7 were superior to S8, S9 and S10 (P<0,05). Results suggest that the 75 up to 200 mOsm/L solution would be bestfor using in HOST when raw semen of rams is analyzed.
