I just googled this ( i guess I could have done that before) and found info that is pretty interesting. Here it is in case anyone else is interested...
Just so that you know, fresh human urine is sterile (unless there is a urinary tract infection – this urine should not be used) and so free from bacteria.
I recommend that you dilute urine to 10-15 parts water to 1 part urine for application on plants in the growth stage. Dilute to 30-50 parts water to 1 part urine for use on pot plants as they are much more sensitive to fertilizers of any kind.
Trees, shrubs and lawn should cope well without dilution. Withhold the use of urine liquid fertilizer on all food plants at least two weeks before harvesting. Apply under fruiting plants, not directly on foliage.
Don’t use urine older than 24hours on your plants as the urea turns into ammonia and will burn your plants. If it’s not fresh, add it to your compost heap. Adding undiluted human urine to your compost heap will help heat it up quickly as it is an excellent activator and will add to the final nutrient value.
As far as antibiotics, vitamin supplements and other medications go, yes they will end up in your urine, but in such minute quantities that I believe to be negligible – especially when it is diluted.
So put this excellent source of free liquid fertilizer to good use in your garden, rather than add to the burden that we as humans cause to our environment.
I feel your pain though, I've always put so much trouble into manipulating things so there'd be more females, but I guess it's all for nada.
