<s>[INST] My husband takes 70mg of Vyvanse and 30mg of time released Adderall everyday. He sometimes goes over in a daily dose and takes more. He recently took a sperm test because we have been trying to have kids. His test showed that he has abnormalities in motility, morphohlogy and sperm count. He is in denial that the medication has anything to do with his sperm. Can you please tell me if it does ? [/INST] Hello and Welcome to ‘Ask A Doctor’ service.I have reviewed your query and here is my advice.Vyvanse is a psychostimulant drug and is known to cause altered sexual ability or desire such as hypersexuality, male impotence, premature ejaculation, etcetera.Adderall is a amphetamine which has abuse potential, which seems to be causing him to go over the prescribed doses. But it is not known to have any effect on fertility.You must consult your doctor and bring the issue in front of him. Vyvanse could be having its side effect on your husband's sperms.Hope I have answered your query. Let me know if I can assist you further.Regards,Dr. Jitender Chauhan </s>
