ISO 23162 – new standard for basic semen examination – specification and test methods is now available.!
A new international standard for sperm analysis was needed to ensure that the methods are standardized and that they give reliable results. It will be of great benefit for the patient, give better and efficient treatments and make it easier to have multicentre studies.
The result of a very positive cooperation between experts in several countries, led by Dr Lars Björndahl.
We recently received an excellent question: How do you assess sperm vitality with Sperm VitalStain in viscous sperm samples? First, we recommend diluting the sample using PureSperm Buffer when preparing a smear from raw ejaculate. This makes the procedure easier and...
All our products can be transported without a cold chain and stored at room temperature until opening. This simplifies logistics and provides a more environmentally friendly alternative to temperature controlled transport. To ensure reliability, we have conducted...
Achieving consistent, high-quality sperm preparation results depend heavily on maintaining optimal sample conditions. Two common challenges—rising osmolality over time and high semen viscosity—can compromise sperm function and reduce recovery rates. PureSperm™ Buffer...
PureSperm™ owes its performance to a precisely engineered colloidal silica system. The silica particles are synthetically produced and undergo silanization, a chemical process that stabilizes their surface and prevents aggregation. This creates a uniform, stable...
As the holiday season approaches and many of us are longing for colder winter weather, it feels fitting to highlight how Sperm CryoProtec protects sperm during the freezing and thawing process. The role of glucose in Sperm CryoProtec Osmotic balance: Glucose acts as...
Light-Protective Packaging for Embryo and Gamete Safety To ensure the highest level of safety for embryos and gametes, NidOil™ is packaged in amber, screw-top bottles that protect against light-induced changes. This precaution is based on documented cases where...
Like the gut, the uterus contains a mix of bacteria—known as the endometrial microbiome. Though once thought to be sterile, research shows the uterus hosts beneficial and harmful bacteria. Why It Matters for Pregnancy An imbalance in uterine bacteria, especially low...
This unique microbial community resides within the uterus and plays a vital role in reproductive health. In a balanced environment, Lactobacillus species dominate, producing lactic acid that helps maintain an acidic pH and suppress the growth of potentially harmful...
Bubbles seen in IVF media after transport do not generally affect the quality. They are often a result from the presence of human serum albumin (hSA)- a common additive in culture media, like in PureSperm Wash. HSA contains both hydrophilic and hydrophobic regions....
Two types of high quality sperm separations Nidacons product SpeediKit and a regular density gradient both serve the purpose of creating high quality sperm separations however, there are some distinct advantages to SpeediKit over a traditional density gradient. Key...
