P.R. Laws Ap. tit. 34A, § II, Rule 154
Upon trial for the crime of procuring or attempting to procure an abortion, or aiding or assisting therein, or for inveigling, enticing or for inducing or deceiving an unmarried female, under the age of twenty-one (21) years, until then reputed to be chaste, to enter a house of ill repute or any other place for the purpose of prostitut[ing] her or aiding or assisting therein or for having unlawful carnal relationship with any man, or upon trial for seduction under the promise of marriage, the defendant cannot be convicted upon the sole testimony of the aggrieved woman unless such testimony is corroborated with some evidence which by itself tends to establish the relationship of the accused with the commission of the crime. This corroboration shall not be sufficient if it only proves the perpetration of the crime, or the circumstances thereof.
