The word "penile" is often used in medical or scientific contexts to refer to the male reproductive organ. However, there are other synonyms that can be used in place of this term. Some of the most common ones include "phallic", "organ" or simply "genitals". These synonyms are more general and can refer to both male and female reproductive organs, which may be more appropriate in certain situations. Additionally, slang terms such as "dick" or "cock" may be used, but these should be used with caution as they can be considered vulgar or inappropriate in many settings.
