About this trial
This clinical interventional study aims to assess whether treatment with with leflutrozole can improve sperm production in infertile men with non-obstructive azoospermia selected by serum anti-mullerian hormone (AMH) or Inhibin B as a positive predictive biomarker.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Signed informed consent by participant
Signed informed consent by participant's partner (must just be obtained before the par-ticipant starts treatment at Visit 1), if applicable, regarding blood samples, data collec-tion about fertility treatment as well as pregnancy and pregnancy outcome
18-55 years
Azoospermia verified by at least 2 semen samples, average semen volume >= 1,0 ml with no identifiable sign of obstruction (samples taken at Visit -1 and at Visit 0 prior to confirmation of eligibility and dosing).
Disqualifiers
Klinefelter or other major genetic conditions including large deletions on sex chromosomes
Average testis size > 20 mL unless obstruction has been excluded
TESE procedure < ½ year ago
LH concentration > 15 IU/L at screening

Treatment groups
Trial outcomes
Primary outcomes
Proportion of patients with spermatozoa in the ejaculate at Week 12-20.
The primary endpoint is proportion of patients with spermatozoa in the ejaculate at Week 20 (end-of-treatment).
Secondary outcomes
Change in serum reproductive hormones
Change in serum concentrations of follicle-stimulating hormone (FSH), luteinizing hormone (LH), total testosterone, estradiol, inhibin B, anti-Müllerian hormone (AMH), and sex hormone-binding globulin (SHBG).
Change in seminal fluid reproductive biomarkers
Change in concentrations of RANK ligand (RANKL), osteoprotegerin (OPG), anti-Müllerian hormone (AMH), and inhibin B measured in seminal
Change in reproductive hormone ratios
Change in serum inhibin B/FSH ratio, testosterone/LH ratio, testosterone/estradiol ratio, and AMH/testosterone ratio.
Change in body mass index
Change in body mass index (BMI) weight and height will be combined to calculate BMI in kg/m\^2
