<s>[INST] Had a sperm count which was very low and had been taking malarone approx 3 months before that. Could this affect the result? Also the count was 1.2. Million and the motility reading was OCC MOT OCC IMMOTILE - do you know why that is? Our doctor did not explain it well and we are very worried it will not be possible to conceive. Thank you so much [/INST] hello thank you for writing to HCM Malarone really does not cause such a dramatic drop in the sperm count You should consider doing your sperm count once more before coming to such a diagnosis If found to be low - further tests can be done to identify the cause and what treatment can be offered hope to have answered your query Dr Nandita Thakkar </s>
