Association between periodontal status and idiopathic male infertility

Abstract

About 30% of male infertility cases are idiopathic. Previous studies reported a positive correlation between deep periodontal pockets and sperm sub-motility, which suggests that periodontitis might have a role in idiopathic semen abnormality pathospermia. We evaluated correlations between periodontal infection parameters and the results of sperm analysis of men with idiopathic infertility. In this observational study, semen quality and periodontal status were analyzed for 95 otherwise healthy men attending an andrology unit for sperm analysis. Half the men in the sperm pathology and normozoospermia groups (50.8% and 50%, respectively) had poor periodontal status. Among the 95 participants, 38% had oligozoospermia, 28% had asthenozoospermia, 16% had cryptozoospermia, and 15% were classified as normozoospermic. Sperm pathology category was not associated with frequency of deep periodontal pockets or calculus. Bleeding on probing was significantly lower among men with asthenozoospermia than among those with normozoospermia. Poor periodontal status was not associated with any sperm pathology category or parameter. In contrast with previous findings, the present results indicate that pathospermia and poor semen quality are not associated with periodontal infection in men with idiopathic infertility.

Idiopathic male infertility related to periodontal and caries status

“…Similarly to our previous study (Pasztor et al., ), significant correlation was found in a few analyses; for example, average number of teeth with calculus was higher in patients with combined oligo‐asthenozoospermia than with normospermia ( p = .048).…”

Relationship between periodontal disease and male infertility: A case–control study

“…A study by Pásztor et al. (2016) showed that poor periodontal conditions were not associated with any semen parameter abnormalities.…”

Interaction between oral diseases and other health-related factors

“…Both study protocols were approved by the Regional and Institutional Human Medical alcohol consumption and substance abuse) were collected via a self-administered questionnaire, followed by andrological and periodontal examinations [83,84].…”

“…The following exclusion criteria were defined: varicocele or testicular microlithiasis (confirmed by ultrasound examination); hypogonadism (verified by hormonal measurements); genetic disorders (determined by chromosome analysis or molecular genetic investigations) or symptoms of urogenital infection. Patients w ith azoospermia (no spermatozoa in the ejaculate) were also excluded due to the possibility of seminal duct obstruction or serious testicular abnormality [84].…”

“…The dental and parodontal parameters of oligozoospermia, asthenozoospermia, cryptozoospermia and of the sperm pathology group (men with any sperm abnormality) were compared to men with normozoospermia ( control group). Patients with oligoasthenozoospermia were considered in both the oligozoospermic and asthenozoospermic groups [84]. No information about the andrological status of the patient was available for the dentist at the time of the dental examination.…”
