Objective:
To report two consecutive spontaneous pregnancies in a compound heterozygous patient with classic galactosemia and a heterozygous partner, 6 years after ovarian tissue cryopreservation.
Design:
Case report.
Setting:
Tertiary health care center.
Patient(S):
A patient with classic galactosemia and strict adherance to a galactose-free diet.
Intervention(S):
Right ovariectomy by laparoscopy and cryopreservation of cortical slices; metabolic follow-up.
Main Outcome Measure(S):
Genotyping, galactose-1-phosphate uridyltransferase (GALT) activity and erythrocyte galactose-1-phosphate determination, histology of ovarian cortex, pregnancy achievement.
Result(S):
Undetectable GALT activity; compound heterozygosity: association of c.563A>G (p.Gln188Arg) and a novel mutation c.982C>T (p.Arg328Cys); rare growing follicles and abnormally low primordial follicles; two uneventful spontaneous pregnancies without need for autografting of the cryopreserved tissue.
Conclusion(S):
The risk for ovarian failure is a frequent concern, but spontaneous pregnancies may occur, even repeatedly, in young patients with galactosemia. Thus, there is a need for more accurate predictive factors to guide the indication for ovarian tissue cryopreservation, the benefits and risks of which have to be balanced through a multidisciplinary approach.
