OBJECTIVE: To explore the feasibility of biological fatherhood in nonobstructive azoospermia patient with Kennedy's disease and review the relevant literature.
METHODS: A twenty-eight man complaining of weakness in the lower extremities for a year underwent physical and laboratory examinations and was found with azoospermia. At the request of the patient for assisted reproduction, we performed microdissection testicular sperm extraction (micro-TESE).
RESULTS: Physical examination showed grade-4 and grade-4+ muscular strength in the proximal and distal lower extremities, respectively. The levels of Creatine kinase (CK), serum follicle-stimulating hormone (FSH), luteinizing hormone (LH) and testosterone (T) of the patient were 432 U/L,18.1IU/L,10.4 IU/L and 8.6 nmo/L, respectively. The peroneal motor nerve conduction velocity was significantly decreased. Examination of the androgen receptor (AR) gene revealed 56 CAG repeats in exon 1, which confirmed Kennedy's disease. The patient was found with testicular atrophy and mild gynecomastia but normal seminal plasma biochemical parameters and peripheral karyotype and no Y chromosome microdeletion. Some sperm were found in micro-TESE though none in the previous testicular biopsy. Immunoradiometric assay showed a serum β-HCG level of 873 IU/L at 2 weeks and ultrasonography manifested clinical pregnancy at 4 weeks after in vitro fertilization-embryo transfer following intracytoplasmic sperm injection (ICSI). At 38 weeks and 2 days of gestation, a healthy boy was born by caesarean in a local hospital.
CONCLUSIONS: Nonobstructive azoospermia patients with Kennedy's disease can achieve biological fatherhood via micro-TESE and ICSI.
