Summary
The project's background: Sickle cell disease is, at present in France, the most frequent
genetic illness. Recent progress in its treatment, in particular the use of hydroxyurea, has
considerably modified the prognosis of this disease. Many more patients now reach
reproductive age and do consider fathering. Exceptional studies have reported the potential
impact of this medical treatment on the sperm parameters and fertility of male patients. In a
retrospective analysis, the investigators found that the observed alterations of semen
parameters due to sickle cell disease seem to be exacerbated by hydroxyurea treatment.
The study hypothesis: A large prospective study is essential to assess the potential adverse
impact of the medical treatment of sickle cell disease on spermatogenesis and consider the
advisability of proposing sperm cryopreservation before this treatment is started.
Primary purpose of the protocol: evaluate the impact of a treatment by hydroxyurea (20-30
mg/kg/day), 6 months after its beginning, in 34 men with sickle cell disease (18-60 years
old). The main trial criterion will be the average difference of the concentration of
spermatozoa s (millions/ml) in the ejaculate, before and after 6 months of medical treatment.
