1.
Do not have unprotected s-ex. Se-xually-transmitted diseases, such as for
example gonorrhoea and Chlamydia, may damage the sperm-producing cells
that block the tubes carrying sperm from the testis to the penis.
2. Avoid pesticides that control pests in the garden and on the farm. Such chemicals may damage the sperm-reproducing organs.
3.
Avoid insecticides sprayed to kill mosquito. Such chemicals may damage
the sperm- reproducing organs. Therefore, if you must spray your room
against mosquitoes, allow a minumum of one hour before you go back once
again to the room.
Continue after the break.
