Kallman's syndrome is a genetic condition which causes low levels of
gonadotrophin releasing hormone (GnRH). This, in turn, leads to low levels
of lutenising hormone and follicle stimulating hormone (plus other
physical problems in some people). The person with Kallman's syndrome
doesn't develop normal gonads unless they are given the releasing
hormone in injection form - according to the book I'm getting the
information from. I would imagine that it could cause fertility
problems.
In lactating women, there are lower than normal levels of GnRH, FSH
and LH, especially in the early weeks. In this case, I'm not sure if
Kallman's syndrome would have any effect on lactation It would be
interesting to know if there is another reason for this woman's
lactation failure, or if there is some hormonal treatment that she is
on that could affect lactation.
Hope this helps
