A sperm sorting device that can help infertile couples

NEW YORK — Researchers have built up a new device that can sort the best sperm out of millions in just 30 minutes for their use in assisted reproductive technologies such as in vitro fertilisation.

With this device, the couples who are looking for having a baby on their own but find it difficult to conceive will be able to fulfill their dreams of having healthier babies.

The device, based on microfluidic technology, reduces risk of DNA damage associated with conventional sperm sorting method.

Around the world, about 48.5 million couples have been been unable to have a child after trying for five years or more. While in vitro fertilization, 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.

“DNA damage is one of the more important characteristics of sperm, because higher levels of damage are associated with lower pregnancy rates, early loss of pregnancy, and increased disease rates of offspring who are conceived through assisted reproductive technologies,” said Waseem Asghar, Assistant Professor at Florida Atlantic University in the US.

“That’s why it is so important to develop methods to select the healthiest sperm for assisted reproductive technologies,” Asghar noted.

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.

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.

The findings were presented in the journal Biotechnology Advances.

Man divorces wife just 15 minutes after Islamic marriage in Dubai

A man in Dubai divorced his bride just 15 minutes after their Islamic marriage as he felt ‘insulted’ by her father’s bride price demands.

The man agreed to pay his new father-in-law Dh100,000 for their wedding but the older man became impatient to get the cash, DailyMail reported.

According to Gulf News, family members and friends accompanied the couple to a Sharia judge’s office to witness the marriage contract being signed. The groom then gave Dh 50,000 on the spot as agreed, with the rest to come after the party left the court building, according to Gulf News.

But, the bride’s father demanded the remaining cash as soon as the signing was over, even though the groom didn’t have it on him.

He said it would only take five minutes to walk to his car, which was parked outside, and get the rest of the bride price.

Instead of letting him retrieve it, the father insisted him to pay either right then or send a friend or relative to get the money while he stayed inside.

The groom felt insulted and demeaned by the series of demands and called off the marriage immediately, a lawyer handling the case said.

‘He told the bride’s father that he did not want his daughter as his wife and divorced her in less than 15 minutes from signing the marriage contract,’ he said.
