A new LH receptor splice mutation responsible for male hypogonadism with subnormal sperm production in the propositus and infertility with regular cycles in an affected sister

摘要

BACKGROUNDInactivating LH receptor (LHR) mutations have been described so far in men as well as in women. Phenotypes in men have been variable with in nearly all cases impairment of sex differentiation or azoospermia. We report a milder reproductive phenotype both in a male patient and his sister.
