Thanks for your query.Based on the facts that you have posted it appears that you have staphylococcal infection
of the seminal vesicle
or prostate confirmed on semen culture.
Please continue taking antibiotic prescribed by your family Physician at least for 1 month and repeat semen culture again.
You need to treat your wife simultaneously with same antibiotics for a month.
Once semen is sterile get your semen analysis
done to assess the sperm count, sperm motility
and morphology of the sperms .If all the parameters are within normal range there is no reason why you should not impregnate your wife.
