Fertility Treatment????

[Gregory Matthews]

The following may be reviewed at National Geographic, October 2016, "Speedy Delivery," page 18 & 19.

Infertility is often (not always) caused by male sperm that are sluggish swimmers, for some reason or another.  [NOTE:  It may be 20% of the time.]

A mechanical motor, named "spermbot" has been designed.  It wraps around the sperm's tail and propels   the sperm off, hopefully to unite with an egg.  It can be driven magnetically. 

NOTES:

1)  At the present this is only done in a lab.

2)  It has not yet been attempted on humans.

3) So far it has been attempted on cows and it has not been successful.

4) Scientists in Germany continue to work on it.

The National Geographic article contains a photograph of a sperm with an attached motor approaching an egg.

I think it's on page 25 & 26...

That is the page, whatever the number is.  My edition of the NG seems to be numbered differently than yours.  Perhaps it is the advertising pages  which may differ from region to region.  I do not know.

I have the answer:  As is common in documents that are filed in digital form, the print document is paged differently from the digital file.  In this example, page 38 in the print edition is actually page 45 in the digital file.

In my opinion, in the majority of infertile couples [humans, that is] it is the wife who is infertile.  Male infertility doesn't seem to show up so often, and is easily cured in the doctor's office lab.

 

For farmers, of course, the male cattle infertility would be important; it would impinge on their earning power.
