thank you for posting your query in healthcaremagic.com... well your doctor must have examined and investigated both you and your wife for infertility....and after that prescribed these drugs to you.... well for fertilisation and eventually pregnancy to occur, there must be good sperm motility, sperm count and morphology...any of these below the normal level can lead to infertility.... FERTISURE M is used in low sperm motility or movement and Q GOLD is used in low sperm count , motility or morphology.... using these regularly may lead to reversal of male factor and also unknown factor infertility... hope this was helpful.... contact me for any further queries... regards
