Cannabis is a dioecious plant meaning there are female and male types. Whilst you probably klnow this the way they work is very much the same as other male/female sexual species. the male produces pollen (think sperm) and the female has the propensity to produce seeds if fertilized (think of a seed as a zygote).
You should kill the male and move on. It can't give you bud or seeds or anything useful really. Waste of time and space and likely to screw up other grows around you making their sweet ladies pop a couple seeds thanks to your pollen.
if you have females going now move mmale to another room under some kind of light until polen is produced
collect polen and sprinkle on bottom branches of female carfully if not to late in femail flowering
if so dry polen and save in freezer for next grow if you are interested in seeds dont kill male like advised
and if you are growing do more reading im i started this year and try to read everything i mean everything i go to diff sites and read to barnes and nobile and read read all posts and replys interested or nr not
