It depends on why the man is sterile. There are many causes. If he has had a vasectomy, an operation to make him sterile, that operation can now be reversed for a majority of men, if they want to go through the hassle and expense. If a man is sterile for some other reason, there are many possible medical reasons and many possible treatments. Only a fertility expert knows all about it.

A sterile man typically cannot father biological children because sterility refers to the inability to produce viable sperm. However, there are options available for men who are sterile, such as using donor sperm or exploring assisted reproductive technologies like in vitro fertilization (IVF) with a surrogate. Adoption is another avenue for building a family. Each option allows for the possibility of parenthood despite infertility.
