Innovative Approach: L-HIS Method in Turkey
What you need to know about L-HIS Method.
What is L-HIS Method?
L-HIS Method, which stands for Long-Term Hormonal Induced Spermatid Spermiogenesis, represents a significant breakthrough in the treatment of non-obstructive azoospermia. This method has been meticulously developed and refined to offer hope to patients who have traditionally faced limited options.
L-HIS Method is an approach aimed at stimulating sperm production in the testes through long-term hormonal and phytotherapeutic treatment. Essentially, it is based on regulating hormonal balance and supporting cellular processes to facilitate the transformation of spermatogonial stem cells into mature sperm cells. The effects of hormones such as follicle-stimulating hormone, luteinizing hormone, and testosterone on sperm production have been determined through years of research.
Scientific rationale: the efficacy of the protocol is based on three established biological principles. First, for normal spermatogenesis, intratesticular testosterone concentrations must exceed serum levels by 50-100 times. Second, activating STRA8, which is the master regulator of meiotic entry and acts as the molecular 'switch' for germ cells to exit mitotic proliferation and enter meiosis, directly addresses its potential intratesticular deficiency. Third, FSH support maintains Sertoli cell function, providing the structural and nutritional scaffold for developing germ cells.
Non-Obstructive Azoospermia (NOA)
Non-obstructive azoospermia (NOA) is a challenging condition where the testicles fail to produce sufficient mature sperm cells due to underlying issues in spermatogenesis. Unlike obstructive azoospermia, where sperm production is normal but blocked from exiting the body, NOA often results from genetic, hormonal, or environmental factors that disrupt the normal development of sperm within the testicular tissue.
L-HIS Method offers a structured, evidence-based approach for non-invasive spermatogenesis restoration in patients with NOA (Non-Obstructive Azoospermia). Combining hormone optimization, pathway activation, and meticulous laboratory techniques, this protocol achieves haploid cell retrieval rates that call into question the necessity of primary surgical intervention in specific patient groups.
We recommend L-HIS Method be considered as a first-line approach in suitable NOA candidates, and also for patients in whom sperm could not be found after a previous micro-TESE. This "biological restoration first, then surgery" philosophy aligns with the principles of minimally invasive medicine while preserving testicular function for potential future treatments.
L-HIS Method: How it works
L-HIS Method Ankara is designed to address the root causes of non-obstructive azoospermia by stimulating the body’s natural ability to produce mature sperm cells from spermatogonia, the precursor stem cells in the testes. The treatment protocol is comprehensive, involving the following key phases:
Hormonal stimulation.
Carefully monitored hormonal therapy to promote sperm maturation.
Phytotherapy integration.
Natural supplements enhance hormonal therapy effects.
Long-term monitoring.
Regular assessments ensure continuous improvement.
Clinical success.
Groundbreaking results with a 70% success rate.
Why choose L-HIS Method in Ankara, Turkey?
L-HIS Method is more than just a treatment; it is a beacon of hope for those facing the daunting challenges of non-obstructive azoospermia. Here’s why this method stands out:
- Personalised treatment plans: Each patient receives a treatment plan tailored to their specific needs and biological responses, aiming to optimise the success rate for each individual.
- Long-term commitment to success: Unlike short-term interventions, L-HIS Method is designed to provide sustained results, giving patients the best chance of achieving biological fatherhood.
- Cutting-edge research and innovation: Turkey L-HIS Method is based on the latest research in reproductive medicine, combining the best of hormonal therapy with natural supplements to create a powerful synergistic effect.
L-HIS Method in Ankara, Turkey?
L-HIS Method is generally applied to patients who have not achieved results with other treatment methods. The treatment process is personalized based on the patient’s overall health and sperm production capacity. In general, the treatment includes the following stages:
Phase 1: Molecular Triggering and Hormonal Optimization (Weeks 0-12)
The primary goal of Phase 1 is to create an optimal hormonal environment for spermatogenesis by maximizing intratesticular testosterone and providing FSH support for Sertoli cell function. Simultaneously, adjunctive drug therapy is added to trigger meiotic entry.
Monitoring
Basal hormonal panel (FSH, LH, total testosterone, estradiol), liver function tests (ALT, AST), and lipid profile. Repeat at weeks 4, 8, and 12.
Phase 2: Maturation support and mRNA assessment (Weeks 12-16)
Phase 2 maintains the hormonal and treatment regimen while initiating ejaculate screening. In refractory cases with persistent meiotic arrest, treatments targeting SPO11 or SYCP3 proteins may be considered under appropriate ethical and regulatory frameworks.
Phase 3: Intensive ejaculate screening - 'Shaking technique' (Weeks 16-24+)
This phase represents the critical laboratory component of the protocol. The 'Shaking Technique' is a meticulous, multi-step ejaculate processing method designed to identify rare haploid cells that may be present following medical treatment.
Who is suitable for the L-HIS Method in Ankara, Turkey?
L-HIS Method is indicated for men diagnosed with NOA who meet the following inclusion criteria:
- Confirmed NOA diagnosis (≥2 semen analyses with azoospermia), detection of spermatids
- Histopathological pattern of maturation arrest or hypospermatogenesis
- Klinefelter syndrome (47,XXY) with residual testicular function
- AzF-c or AzF-c+d microdeletions (partial deletions with spermatid production potential)
- Azoospermia after chemotherapy or radiotherapy with evidence of gonadal recovery
- Idiopathic NOA with high FSH but detectable inhibin B
- Age 18-55
- Normal hepatic function (ALT, AST within normal limits)
- Complete AzF-a or AzF-b deletions (complete absence of germ cells)
- Y chromosome microdeletion involving the entire AzF region
- Severe hepatic impairment or active liver disease
- History of psychiatric disorders (relative contraindication for isotretinoin)
- Partner pregnancy during the treatment period (risk of teratogenicity)
- Failure to detect spermatids in a previous unsuccessful micro-TESE with complete SCO histology
Advantages and disadvantages of L-HIS Method in Turkey
L-HIS Method advantages
- High success rate: Higher success rates are achieved compared to traditional methods.
- Minimally invasive: Does not require surgical intervention.
- Painless and comfortable: The treatment process is generally painless and comfortable.
- Applicable to a wide range of patients: Can be used in patients with azoospermia due to various causes.
- Personalised treatment: Treatment plans are created according to each patient’s specific condition.
L-HIS Method disadvantages
- Long treatment duration: The treatment duration is longer compared to other methods.
- Cost: The cost of treatment may be higher compared to other methods.
- Side effects: Like all medications, hormonal and herbal treatments can have side effects. These side effects are usually mild and temporary.
- Limited scientific studies: There are not yet enough long-term and large-scale studies on L-HIS Method.
Comparison with surgical approach
While micro-TESE is highly effective, it has inherent limitations. Surgical intervention is invasive, can cause permanent testicular damage (especially with repeated procedures), and does not address the underlying biological dysfunction. Furthermore, even when sperm is surgically retrieved, it may originate from isolated foci of spermatogenesis, potentially limiting the number of usable cells. In contrast, L-HIS Method Turkey aims to restore systemic spermatogenic function, potentially providing ongoing sperm production instead of relying on a single surgical harvest.
