In our 35 years of experience in helping people get pregnant, we have learned that it is better to have two opportunities to fertilize the egg during ovulation. Every woman is different, but two inseminations timed approximately 12 hours apart should cover the most critical fertile window during ovulation.

*Each sperm straw is&nbsp;0.5 ml. Two straws will add up to&nbsp;1 ml&nbsp;of sperm. Purchasing two MOT10 straws would provide your patients with at least 10 million sperm.
We determine the sperm quality according to WHO&rsquo;s Laboratory Manual. In all our laboratories, we use CASA (Computer Assisted Sperm Analyzer) to count the sperm cells via microscopy. We count 500 cells or 5 frames (whichever is achieved first) before determining the result of the analysis. CASA ensures a more consistent count than what is possible through a manual process.
However, sperm is a biological material and extremely sensitive to a number of factors, including temperature. This means that a variance in the exact motility can be expected when comparing two independent analyses of a sperm sample. At Cryos, we accept a difference of 20%.
We always do our best to ensure that the number of active sperm cells equals the stated motility or more (e.g., a MOT10 straw includes at least 10 million active sperm cells per milliliter sperm), and in many cases, the sperm sample will prove to have a higher motility than stated. However, if, after following our straw-handling protocol, the post-thaw count shows a motility that is more than 20% lower than the stated motility of the sperm sample, please fill out this <a href="https://www.cryosinternational.com/en-us/us-shop/professional/how-to/how-to-file-a-donor-sperm-complaint/" target="_blank" rel="noopener">Complaint Form</a>, and we will then, together with our laboratory staff, evaluate your claim. If you have any questions, you are welcome to contact our Clinic Account Team.
The graph below shows the percentage rate of getting pregnant versus the total sperm count in a sperm sample (millions) using aggregate data. This data is predominantly for clinical IUI inseminations to reduce variable factors like timing, and it shows there is a big difference between the likelihood of getting pregnant using one MOT5 straw for example (guaranteed minimum of 2.5 million sperm per straw) compared to one MOT10 straw (guaranteed minimum 5 million sperm per straw), and the recommended two MOT10 straws (guaranteed between 10 million sperm and 19 million sperm).

The pregnancy rate when using two MOT10 straws is about 12.5%. This is a 50% increase from the pregnancy rate when using a MOT5 with 2.5 million motile sperm for insemination. The rates continue to increase steadily up to 20 million sperm, and then start to plateau. Therefore, higher MOT levels can be used, but usually, because it is a personal preference versus a higher chance of pregnancy. Cryos has straws ranging from MOT5 &ndash; MOT30+.
