Peter Frederiksen, 63, was arrested two months ago after the gruesome find in his home in South Africa.
Surgical equipment and anaesthetic drugs were also said to have been found in the property, that the Dane had shared with his wife, 28-year-old Anna Matseliso Molise.
The woman allegedly told police that he had drugged her and cut off her private parts while she was incapacitated.
Tragically, Anna was meant to testify against her husband but she was gunned down while leaving her house last month.
Police believe the other women affected are from the Lesotho area in South Africa, and that they were sedated before performing the operations.
However, it is not known if the woman would have survived the attacks.
A Police spokeswoman said that Frederiksen had kept a clear record of every body part he had removed since 2010.
The gun shop owner faces charges of sexual assault, intimidation and breaking medical laws.
