In 1999, Cecos (Centre for the Study and Preservation of Human Eggs and Sperm) in the Cochin Hospital in Paris set up a program for Artificial Insemination by Donor (AID) of female partners of female-to-male transsexual men (transmen). The project met with some resistance, and the issues were discussed in meetings of the Ethics Committee: questions were raised as to the transman’s mental health, his ability to be a father, and the child’s future development âwould this be normal, particularly as regards the construction of his or her gender identity? The parents were offered a follow-up evaluation of their children in order to decide whether these objections were in any way relevant. If so, the program would be halted; if they were unfounded, the program would be maintained and perhaps adopted by other Centers in France. The proposed follow-up was accepted by the parents who were seen with their children at the end of the child’s first year, then once every two years thereafter in a consultation framework. Between 2000 and 2010, 42 children (28 boys and 14 girls) were born to 29 couples. By the end of 2010, 24 of these children had participated in our follow-up study; the others would be seen the following years. These are not homosexual couples. They are in a steady relationship; the fathers fulfil their function competently. They are, nevertheless, fathers without a penis, who identify with the masculine and paternal values of their culture. The children are in good health, their development is normal, they seem happy and consider themselves as either boys or girls, in harmony with their biological sex. It was recommended that the parents tell the truth about AID and the father’s transsexualism. As for the AID, it has rarely given rise to problems. As regards their transsexualism, in spite of their wish to talk to their child about it, many fathers did not find appropriate words. A booklet, written and illustrated by one of them, was helpful for the others, showing that they need only to talk in fairly simple terms about their childhood as they had experienced itâsomething that they did not do spontaneously. There is no reason to regret having helped transmen to become fathers. It will be interesting to see how their children experience adolescence.
