It's common knowledge that endocrine disorders -- diabetes for example -- can have an effect on men's sexuality, and even reproduction. The connection with thyroid disease, however, has never been formally studied...until now.
In a study released in the December 2005 issue of the Journal of Clinical Endocrinology & Metabolism, researchers reported on the connection between specific sexual problems in men and thyroid conditions -- including hypothyroidism and hyperthyroidism -- in those men.
The study looked at 48 adult men, 34 with hyperthyroidism and 14 with hypothyroidism. The men were evaluated for a number of common problems, including a low sex drive (hypoactive sexual desire), erectile dysfunction, premature ejaculation, and delayed ejaculation. They were examined twice, once while symptomatic, and a second time approximately 8 to 16 weeks after their thyroid levels had returned to normal range.
Among HYPOTHYROID men...
- Low sex drive, delayed ejaculation and erectile dysfunction was a complaint in 64.3% of men
- Premature ejaculation was a complaint in 7.1% of men
- Premature ejaculation was a complaint in 50% of men
- Low sex drive was a complaint in 17.6% of men
- Erectile dysfunction was a complaint in 14.7%
- Delayed ejaculation was a complaint in 2.9% of men
The Good News?
According to the researchers, proper diagnosis, and treatment to return a man to "normal" thyroid function -- known as euthyroidism -- was found to reverse most sexual symptoms in men.
