Stress, fear or health issues such as heart disease may cause the penis to malfunction. Asthenozoospermia is when a male’s sperm are not moving well. One might need advice that is tailored to them from a professional on what to do which could involve; talking therapy to reduce anxiety levels, drugs that can help one get an erection, or changing how they live intending to improve their sperm health among others. A sexologist should be consulted for more information on this subject.

It is not advisable to take medicine to stop sex drive without consulting a doctor. Certain medications can lower sex drive, but they should only be taken under medical supervision. Please visit a urologist or endocrinologist for proper advice and treatment options.
