Whether a man can still conceive naturally with oligozoospermia should depend on the actual situation. In mild cases of oligospermia and weak sperm, natural conception may be possible, but the probability of natural conception is low. In severe cases of oligozoospermia, it may cause male infertility and cannot lead to successful natural conception in women.
In men with oligospermia, which usually refers to a reduced sperm count as well as low sperm quality, only mild oligospermia may enable a woman to conceive naturally, but the probability of successful natural conception is low.
When a man has severe oligozoospermia, it may cause male infertility and prevent the woman from conceiving naturally. Therefore, when a man has oligozoospermia, he should undergo further examination to identify the cause, and under the guidance of the doctor, carry out reasonable treatment to restore fertility as soon as possible.
