Reproductive Specialty Center

Reproductive Specialty Center is an independent fertility and reproductive surgery practice in Milwaukee, Wisconsin, built around the work of Dr. Charles H. Koh and Dr. Grace M. Janik. Dr. Koh came to Milwaukee in 1977 as a faculty member at the Medical College of Wisconsin before moving into private practice, and in 1992 he and Dr. Janik reported the first laparoscopic microsurgical tubal anastomosis for reversing tubal sterilization. Dr. Janik is the practice and medical director.

The center is located in the Water Tower Medical Commons building at 2350 N. Lake Drive in Milwaukee, close to Ascension Columbia St. Mary's Hospital, where its surgeons operate.

The practice is known for minimally invasive reproductive surgery, including laparoscopic tubal reversal using specialized micro-instruments, alongside assisted reproduction led by Dr. Janik, who directs its IVF program. Directory listings also describe IUI, egg and embryo freezing, embryo genetic testing, donor egg and sperm cycles and support for gestational carrier and LGBTQ+ family building, though the clinic's own website was under construction in late 2026 and did not list services.
