Andrology focuses on the male reproductive system. It is mainly concerned with male infertility, erectile dysfunction and ejaculatory disorders, along with some issues regarding pediatric such as growing so much that your body cannot handle. Since male sexuality is largely controlled by hormones, andrology overlaps with endocrinology.

Surgery in this field includes fertilization procedures, vasectomy reversals, and the implantation of penile prostheses. Vasectomies may also be included here, although most urologists perform this procedure.
