How can I increase my sperm count at age 50?

Three points are emphasized: (1) the treatments analyzed in this study can improve SPA values in some of the patients with low sperm penetration capacity; (2) of the treatments studied, sperm refrigeration resulted in the largest improvement in sperm penetration capacity; and (3) sperm refrigeration can increase fertilization and PRs during IVF in this select group of patients.

These results suggest that age-dependent downregulation of CFTR in sperm leads to lowered sperm quality in old age sperm.

The results of our study do not support the suggestion that the sperm parameters decrease with age.

These novel findings may indicate deterioration of healthy sperm cell selection process with age.

Testicular sperm extraction should be recommended before the critical age of 35 years.

In this cross-sectional study, declined sperm motility observed in men over 50 years of age might be due to age-dependent changes in epididymal and accessory sex gland function.

We find remarkable similarities in sperm count distributions in cohorts of fertile men from 1951 and 1971 to 1994.

Ultrafiltered sperm medium in considerable dilution can retard the ageing of the sperm.
