Gonadotropin Therapy in Idiopathic Hypogonadal Non-Obstructive

The goal of this clinical trial is to determine whether short-term gonadotropin therapy (hCG + FSH) can increase sperm availability for ICSI in men with idiopathic non-obstructive azoospermia (NOA) and hypogonadism. The main questions it aims to answer are:

Does hormonal optimization improve the likelihood of obtaining usable sperm (via ejaculate or micro-TESE) by Week 16? Does hormonal therapy reduce the need for micro-TESE or improve downstream embryological and clinical outcomes?

Because there is a comparison group, researchers will compare hCG + FSH hormonal therapy with standard-of-care (no gonadotropins) to see if hormonal optimization increases sperm retrieval success and decreases surgical reliance.

Participants will:

Undergo baseline hormonal and semen testing Be randomized to either hormonal therapy or standard-of-care If in the hormonal arm: receive hCG and FSH with monthly dose titration and aromatase inhibitors if indicated Provide semen samples at Weeks 12 and 16 Undergo micro-TESE if no ejaculated sperm are found (timing per protocol) Complete safety assessments and follow-up through Week 16

Standard of Care

hCG + FSH therapy

Other

hCG + FSH therapy with monthly hormone-driven titration (hCG initial ~83 µg SC twice weekly; no preset min/max; target TT >350-900 ng/dL) + FSH 150 IU SC twice weekly (increase to 150 IU SC three times weekly if 'FSH reset' <1.5 IU/L); allow anastrozole 1 mg PO daily /letrozole 2.5 mg half tablet alternate day if T/E <10

Primary outcomes

  1. Success or Sperm Availability

    Time frame: from randomization through Week 16 via ejaculate or micro-TESE

    Sperm Availability for ICSI was defined as the presence of viable sperm suitable for intracytoplasmic sperm injection (ICSI) at any time from randomization through Week 16. Sperm could be obtained either through ejaculate or via microsurgical testicular sperm extraction (micro-TESE). Assessment of sperm availability was performed by a centralized adjudication committee, which was blinded to treatment allocation to ensure objective and unbiased evaluation.

Secondary outcomes

  1. Micro-TESE Sperm Retrieval Rate (SSR)

    Time frame: The Micro-TESE Sperm Retrieval Rate (SSR) was assessed during the period from randomization through Week 16. The outcome was determined based on the availability of at least one viable sperm retrieved via microsurgical testicular sperm extraction (micro-

    Whether sperm are retrieved during micro-TESE

  2. Need for Micro-TESE Surgery

    Time frame: Up to Week 16

    Whether the participant requires micro-TESE

  3. Safety / Harms

    Time frame: Week 16

    All adverse events (AE/SAE) related to treatment or procedure

  4. ICSI Fertilization Rate

    Time frame: Within the ICSI cycle ≈ Day 1-3 after ICSI

    % of injected oocytes that form normal 2PN embryos

  5. Blastulation Rate

    Time frame: Day 5-7 after fertilization

    % of embryos reaching blastocyst stage

  6. Blastocyst Quality

    Time frame: Day 5-7 after fertilization

    Grading of blastocysts based on standard morphology criteria

  7. Top-Quality Blastocyst Rate

    Time frame: Day 5-7 after fertilization

    % of "top-1 quality" blastocysts formed

  8. Clinical Pregnancy Rate

    Time frame: ≈ 6-8 weeks after embryo transfer

    Presence of gestational sac with cardiac activity on ultrasound

  9. Miscarriage Rate

    Time frame: From pregnancy confirmation to 20 weeks gestation

    Pregnancy loss before 20 weeks

  10. Live Birth

    Time frame: Up to delivery (~9 months after embryo transfer)

    Delivery of a live infant
