It is not always possible to determine what causes low levels of amniotic fluid. Oligohydramnios can be caused by a continuous leaking of amniotic fluid. It can also occur when the fetus has kidney failure. After about four months of pregnancy, the kidneys of a normal fetus will produce the amniotic fluid. If the fetus has kidney abnormalities, the amount of amniotic fluid may be too low.
Oligospermia is also known as a low sperm count or oligozoospermia. In oligozoospermia there are fewer sperm cells in the ejaculate than normal. Oligospermia is generally defined as less than 20 million spermatozoa per one ml of ejaculate. Oligospermia is one of the main causes of male infertility or sub-fertility. Sub-fertility is a reduced ability to achieve a pregnancy while infertility is defined as the complete inability to produce a pregnancy after about one year of unprotected sexual activity.
