Halosperm Test
Diagnosing Sperm DNA Fragmentation at Gynatal Timișoara
The Halosperm test at Gynatal Clinic (Timișoara & Arad) is an advanced andrological analysis that measures the degree of DNA damage (fragmentation) in sperm heads. Even with a normal spermogram, high DNA fragmentation (DFI) can cause recurrent miscarriages or IVF failure, this test provides the scientific basis for selecting techniques like IMSI or ZyMot to achieve a successful pregnancy.
Why a Standard Spermogram Isn't Enough
Standard semen analysis only evaluates external parameters: count, pH, motility, and morphology. However, for a healthy embryo to form and develop, the integrity of the genetic material is the "Scientific Gold Standard".
- DNA Fragmentation: Sperm can have ruptures in their DNA strands that are invisible under a standard microscope.
- Consequences: High DNA fragmentation is directly linked to lower fertilization rates, poorer blastocyst quality on Day 5, and an increased risk of spontaneous miscarriages during the first trimester.
Clinical Indications: Who Should Take the Halosperm Test?
In line with our Information Foraging strategy, we recommend this evaluation as part of a comprehensive male infertility work-up, especially in the following cases:
- Idiopathic Infertility: When all standard tests are normal, but conception does not occur.
- Recurrent Pregnancy Loss (RPL): A history of two or more miscarriages.
- Unsuccessful IVF Cycles: Repeated failure of high-quality embryo implantation.
- Age and Lifestyle: Men over 40, smokers, patients with obesity, diabetes, or those exposed to toxic environments/high temperatures.
- Varicocele: This condition generates oxidative stress, the primary cause of sperm DNA damage.
- Severe male infertility
- Before surgical sperm retrieval ( TESE/ micro TESE)
How the Test Works: The SCD Method
The analysis is based on the Sperm Chromatin Dispersion (SCD) technique:
- Preparation: A period of sexual abstinence for 2 to 5 days is recommended.
- The "Halo" Effect: Sperm with intact DNA create a characteristic "halo" around their heads when exposed to specific laboratory reagents. Sperm with damaged DNA have a small halo or none at all.
- Expert Evaluation: A specialist biologist evaluates at least 500 sperm to determine the percentage DNA Fragmentation Index (DFI).
Logistics at Gynatal
Availability: Samples can be provided at both our Timișoara location, reducing "Cognitive Friction" and travel stress for regional patients.
Follow-up Care: If the DFI is high, the medical team led by Dr. Vlad Tucicovschi may recommend antioxidants or advanced selection techniques like IMSI (6000x magnification) or ZyMot (microfluidics) to bypass the damaged cells.
