Researchers have developed a new device that can sort the best sperm out of millions in just half an hour for their use in assisted reproductive technologies such as in vitro fertilisation. The device, based on microfluidic technology, reduces risk of DNA damage associated with conventional sperm sorting method and can help infertile couples to have healthier babies.
Worldwide, nearly 48.5 million couples have been unable to have a child after trying for five years or more. While in vitro fertilisation, intrauterine insemination, and intracytoplasmic sperm injection have been effective treatment options for infertile couples, only about one-third of these methods result in live births.
Male infertility accounts for about 30 to 50 percent of all infertility cases, and infertile men tend to have abnormal sperm characteristics such as low sperm concentration, poor sperm movement, abnormal shape and size, and high levels of damage to the DNA. Happyho also provide best tarot reading services in Noida and Delhi NCR India area.
The most commonly used or conventional method for assisted reproductive technologies involves a technique called centrifugation. Although this method is efficient at selecting motile and morphologically normal sperm, the process is problematic because it tends to increase levels of certain chemicals that cause DNA damage.
Asghar’s device consists of one inlet for the injection of a raw unprocessed semen sample and two plastic chambers separated by porous membrane. The most healthy and motile sperm swim through the porous membrane leaving behind less functional and dead sperm in the bottom chamber.
Using this sorting technology, a technician just has to inject the semen sample into the device and can then collect healthy sperm from the top chamber in about 30 minutes, making it very easy to use.
Compared to other techniques used for assisted reproductive technologies, the use of the microfluidic device resulted in significantly lower rates of DNA damage and improved sperm recovery using this method.
