Ich habe jetzt Information im WWW dazu gesucht und folgendes, leider nur auf Englisch, dazu gefunden:

Antibiotics
Numerous antibiotics have been associated with causing male infertility. The chart below summarizes the names of the antibiotics and their effect on sperm.
How it affects male fertility:
Minocycline Toxic to developed sperm Toxic to bovine (cow) sperm; believed to be toxic to human sperm as well
Nitrofurantoins (nitrofurantoin, furadantin) Interfere with sperm production resulting in decreased sperm count Unknown if lower doses affect sperm to a smaller degree – recommendation is to choose an alternative antibiotic
Macrolides (erythromycin, troleandomycin) May cause reduced sperm motility or sperm death (spermicidal) Present information based on animal data, but believed to apply to humans as well
Aminoglycosides (neomycin, gentamicin) Negative affects on the production of sperm; neomycin can reduce count and motility Other aminoglycosides have not demonstrated any negative effects on sperm in laboratory studies
Sulfasalazine Can cause a decrease in sperm count, motility, and morphology
Reversible after discontinuation of drug. Case reports are in patients being treated for inflammatory bowel disease (IBD)
Dort werden Fluorchinolone nicht erwähnt.

In diesem Artikel werden auch vor allem sulfasalazine erwähnt, die die männlichen Spermien schädigen können, bei Chinolonen werden höchstens minimale Einflüsse auf die Spermien vermutet.
