Kumar, Naina; Singh, Amit K & Choudhari, Ajay R
Background: High rates of sub-fertility and adverse pregnancy outcomes were seen
after age 40. In contrast to oogenesis, spermatogenesis continues in elderly men.
Objective: To retrospectively study the impact of aging on semen parameters in
male partners of infertile couples in the rural area of developing country over 10
years and to find out whether aging affects male factor fertility and various semen
parameters in this part of developing country.
Materials and Methods: In this cross sectional study, the laboratory semen analysis
records of 1219 male partners of infertile couples of a rural tertiary care center of
Central India in a 10-year period from January 2005 to December 2014 were
evaluated into 5 groups based on men age: Group 1: 21-28 yr (n=57); group 2: 29-35
yr (n=450); group 3: 36-42 yr (n=532); group 4: 43-49 yr (n=165), and group 5: 50-60 yr (n=15). Evaluation of all semen parameters were done according to WHO
standard criteria (1999).
Results: The analysis of semen records revealed the significant negative association
of semen volume, total sperm count, sperm motility, and morphology with age.
There was a significant fall in total sperm count, sperm motility, and morphology
after the age of 35 yr.
Conclusion: Age has significant negative effect on semen volume, total sperm
count, and sperm motility and morphology in this region of India.
