Abstract:

Eat. Survive. Reproduce. These are the fundamental functions of all species, including humans. More specifically, we eat to survive, and we survive to reproduce and spread our DNA. However, there exist data that suggest that human reproduction is in peril. The total fertility rates (defined as births per woman over her lifetime) continue to decline and are projected to decline further worldwide (1, 2). Such declines have a profound impact on society because a birth rate of 2.1 is required for a nation to maintain a stable population. If the fertility rate were to fall below such a value (as it has for many countries in the developed world), the economic implications are enormous in terms of the workforce and ultimately tax base for social programs (which are compounded as lifespans increase). Thus, in addition to an academic question, a declining fertility rate has existential implications for a society.

Reproduction is the law of Life.

Reproduction is the law of life. All species which reproduce at a rate faster than their death rate, survive and thrive. When the Reproduction rate goes below the death rate, the species disappears. 

Human beings have survived for several millennia and seem to have lived through many catastrophes. While the man made disaster of climate change and environmental pollution certainly has great health repercussions, it is far fetched to assume that it has reduced spermatozoa concentration. The current evidence is quite unsatisfactory.

Spermatozoa concentration is very variable from time to time(1); it’s estimation has huge Inter observer and Intra observer variation and the methods of evaluation are different. It is an unreliable indicator of man’s fertility. Except in it’s extreme situation of Azoospermia, we are not entirely clear as to what is a Fertile Semen Sample. (2) Under these circumstances, it would be unwise to decide that man’s fertility is declining or to conclude that my father had a higher spermatozoa concentration than me.

Does my father have higher sperm counts than me?- May be, may be not. Does it really matter?
