These days there are all sorts of ways to have a baby -- including using a sperm bank.

Use of donor sperm can be a tremendous boon to those trying to conceive, but the practice is not without some cause for concern.

Take for example a white woman in Ohio who recently sued a sperm bank for mistakenly providing her with sperm from a black donor.

Her case raises some tough questions about how sperm banks are regulated.

To help sort through some of those questions Take Two speaks with Naomi Cahn. She is a professor of law at George Washington University and author of "Test Tube Families: Why the Fertility Market Needs Legal Regulation."
