So, it appears that the lowly cockroach, that detested insect pest, shares more with us ladies than just our kitchens. Biologists at Manchester University, who are undertaking research into increased fertility problems in women who put off having children until they are older, now believe that cockroaches hold the key to the mysteries of women's fertility.
They are particularly interested in the mating behaviour of the dusky roach (Nauphoet cinera). The female cockroach is unusual as she bears live young and also experiences reproductive cycles and becomes less fertile with age. If breeding is delayed, the cockroaches lose reproductive potential apparently due to a biochemical reaction which may be similar to that of human beings. Now, I ask myself, why do scientists spend so much time and so many resources on human fertility when half of the world population is starving?
If we believe what we are told, it is possible that in another fifty to sixty years scientists will have conquered ageing, that inevitable process which causes the human cell to divide and reproduce a finite number of times with increasing errors. If that happens, my great, great grandchildren may be able to look forward to living to be 150 years old but - in what sort of world?
We have problems today with a growing percentage of pensioners compared to the working population. So, shouldn't a curb be put on human reproduction instead of trying to prolong human fertility? Do we really want to see women of sixty or seventy still bearing children? Do we really want to have to carry on working until we are ninety? Is the ultimate fate of mankind to live packed like sardines in mile-high tenements? In such a world, I envisage most people having to work from home because public transport and road systems can no longer cope. A nightmarish future where there are so many people that 'shifts' have to be imposed for recreational purposes or for shopping.
Learning all we can about the human genome is a good thing. But I wonder if scientists are considering all the consequences for humanity when they dream about prolonging human fertility.
