(HealthDay News) — Higher glycemic variability in the hypoglycemic domain is associated with premature ejaculation in young men with type 1 diabetes, although prevalence of premature ejaculation is similar for young men with and without type 1 diabetes, according to a study published in the Journal of Sexual Medicine.

Giuseppe Bellastella, MD, PhD, from the Second University of Naples in Italy, and colleagues examined the prevalence of premature ejaculation in type 1 diabetes. Data were collected from 100 male patients with type 1 diabetes aged younger than 40 years and 51 age-matched controls without diabetes. 

Blood glucose variability was assessed in a subgroup of 30 patients with diabetes (20 with premature ejaculation and 10 without). The premature ejaculation diagnostic tool (PEDT) and the self-estimated intravaginal ejaculatory latency time (IELT) were used to assess the presence of premature ejaculation.

The researchers noted no significant difference in premature ejaculation prevalence between the groups: Pathological values of PEDT score and IELT score were observed in 24% of patients with diabetes and in 23.5% of controls. 

HbA1c was significantly associated with the PEDT score (P=.006) and IELT (P=.01). The PEDT score correlated with low blood glucose indices but not with the standard deviation of blood glucose, mean amplitude of glycemic excursions or low blood glucose indices in the subgroup assessed for glucose variability.

“In diabetic patients with [premature ejaculation], a higher glycemic variability in the hypoglycemic domain is significantly associated with the PEDT score,” the researchers wrote.
