Low serum vitamin D is associated with an increased likelihood of acquired premature ejaculation.

What Was Tested

Researchers studied Vitamin D, K2, Magnesium and Zinc in this observational study publication.

To investigate the relationship between 25-hydroxyvitamin D (25 (OH) D) levels and acquired premature ejaculation (PE).

Who Took Part

According to the abstract, 97 patients were involved.

The age groups tagged for this paper are young adults, adults and middle-aged adults, men only.

A total of 97 patients with acquired PE and 64 healthy men as a control group selected from volunteers without PE attending their Andrology Outpatient Clinic between November 2016 and April 2017 were included the study.

All patients were considered to have acquired PE if they fulfilled the criteria of the second Ad Hoc International Society for Sexual Medicine Committee.

How the Study Was Run

Premature ejaculation diagnostic tool questionnaires were used to assessment of PE and all participants were instructed to record intravaginal ejaculatory latency time.

Vitamin D levels were evaluated in all participants using high performance liquid chromatography method included in the study.

What Was Measured
