Reproductive endocrine issues in men with sickle cell anemia.

In patients with sickle cell anemia, the sickling of red blood cells is known to cause end-organ damage by infarction. In some men who are affected by sickle cell anemia, the obstruction of venous outflow of the penis causes priapism, which could lead to erectile dysfunction. There is also evidence that the disease is linked to other reproductive issues in men-specifically delayed puberty, low testosterone, and sperm abnormalities-although the causes of these problems are less clear. Treatment of sickle cell anemia can have effects on the reproductive system as well. This review summarizes the findings from various publications pertaining to reproductive endocrinology, along with their conclusions and discrepancies.
