Colorado Revised Statutes Title 25. Health § 25-57-109. Donor age limits--limits on number of families per donor--limits on egg-retrieval cycles per ovum donor--rules--applicability

(1)(a) Except as provided in subsection (4) of this section, a gamete agency, gamete bank, or fertility clinic shall make a good faith effort to determine how many families are established with gametes matched or provided by the gamete agency, gamete bank, or fertility clinic from each donor by conducting sufficient record-keeping, requiring recipients, as a condition of receiving donor gametes, to provide information on live births, and requesting information from recipients on live births, and using industry best practices, including methods or processes to account for the number or percentage of live births that are likely not reported, such as the correlation between the number of units of donor gametes sold or released and the resulting live births. A gamete agency, gamete bank, or fertility clinic shall not match or provide gametes from a donor to additional families once the gamete agency, gamete bank, or fertility clinic has record of or should reasonably know that twenty-five families have been established using a single donor's gametes in or outside of Colorado, with no limit on the number of children conceived by each of the families, unless the donor requests, and the gamete agency, gamete bank, or fertility clinic agrees to, a lower limit on the number of families. This limit does not include any children conceived by the donor as a parent or children conceived with the donor's gametes when the donor is known to the recipient parent or parents at the time of the donation. This limit does not include donations of embryos from one family to another family.

(b) For the purposes of this subsection (1), a family is considered established when a recipient parent or parents conceive a child using gametes from a donor and a live birth results or likely resulted. A gamete agency, gamete bank, or fertility clinic shall make reasonable good faith efforts, and document such efforts, to obtain information from a recipient parent about whether and when a live birth has occurred, including requesting such information from a recipient parent or the parent's medical provider using multiple commercially reasonable methods.
