Annual rhythmic variations in sperm counts

Abstract

Four infertile patients were examined in this study and followed up for 5 years from October, 1980 to February, 1986. All the semen samples were examined at monthly interval and were analysed for circannual rhythm. A trend was noted for high sperm count (but subnormal) in December and nil counts during June to October. These patients did not improve in sperm counts even with best treatment provided and showed improvement in counts even without any treatment in winter months, showing a strong circannual rhythm.
Hence, all such cases of infertility should be examined at least twice a year for circannual rhythm and to explore the possibility of treatment in such cases.
