Cigarette smoking is associated with sexual dysfunction and impaired fertility in males. The aim of this study was to determine the potential protective effect of honey against the toxic effect of cigarette smoke (CS) on sexual behavior and fertility of male rats.

Thirty-two adult Sprague-Dawley rats were randomly divided into four groups (8 rats/group) as control, honey (H), CS and H plus CS (H + CS) groups. Rats in control and CS groups received oral administration of distilled water daily while rats in H and H + CS groups received honey (1.2 g/kg body weight/day) by oral gavage. Rats in CS and H + CS groups were also exposed to CS for 8 min 3 times/day. From 10 to 13 weeks of treatment, each male rat was cohabited with 3 untreated female rats for sexual behavioral and reproductive performance studies.

Honey significantly increased the percentages of rats achieving intromission and ejaculation as well as increased mating and fertility indexes of male rats exposed to CS. Thus, honey has a protective effect against CS-induced impaired sexual behavior and fertility in male rats.
