New Research Shows That Women's Eggs Prefer Some Men's Sperm Over Others

A woman’s eggs choose to pick a high quality or genetically compatible sperm during the last moments of conception, study finds.

New Research Shows That Women's Eggs Prefer Some Men's Sperm Over Others

According to a new study, a woman’s eggs may be selective towards sperm cells and prefer some over the others.

The study carried out by Stockholm University, in partnership with the Manchester University NHS Foundation Trust (MFT) looked into the chemicals used by a female egg to attract male sperm and results show that a woman’s eggs may prefer sperm cells of some men to others.

‘Human eggs release chemicals called chemoattractants that attract sperm to unfertilized eggs. We wanted to know if eggs use these chemical signals to pick which sperm they attract,’ said John Fitzpatrick, an associate professor at Stockholm University.

The study specifically looked at follicular fluid, which surrounds the eggs and contains the chemicals that attract sperm.

The study checked if the fluids from different women attracted certain sperm more than others and the result showed it does. The research team obtained anonymous egg and sperm samples from couples undergoing IVF at St Mary’s Hospital in Manchester.

Follicular fluid from one female was better at attracting sperm from one male, while follicular fluid from another female was better at attracting sperm from a different male,’ said Professor Fitzpatrick.

‘This shows that interactions between human eggs and sperm depend on the specific identity of the women and men involved.’

It seems that even if a woman has chosen a partner to mate with, it’s not a must her egg and his sperm will attract each other according to the study.

According to Professor Fitzpatrick, sperm have only one job which is to fertilise the eggs. So they won’t be choosy about which egg they fertilise.

The study suggests that eggs have evolved and now pick high quality or genetically compatible sperm.

“The idea that eggs are choosing sperm is really novel in human fertility
’ said Professor Daniel Brison, the scientific director of the Department of Reproductive Medicine at Saint Mary’s.

‘Research on the way eggs and sperm interact will advance fertility treatments and may eventually help us understand some of the currently ‘unexplained’ causes of infertility in couples.’

Brazilian man becomes first person to be ‘cured’ of HIV with drugs alone

Brazilian man becomes first person to be 'cured’ of HIV with drugs alone

A 35-year-old Brazilian man who has gone into long-term remission after being diagnosed with an accelerated multi-drug regimen of AIDS drugs for less than a year has boosted expectations for a possible breakthrough on Tuesday July 7.
The man who tested HIV positive in 2012 was treated with an antiretroviral therapy or ART base that was boosted with additional antiretrovirals, plus a drug called nicotinamide (a vitamin B3 form).

His increased care was stopped after 48 weeks, and researchers who reported their results at this week’s virtual International Aids Society conference said that the patient has now been without HIV medication for more than 57 weeks and continues to test negative for HIV antibodies.

Dr Ricardo Diaz of the University of Sao Paulo in Brazil, who led the study said he was “trying to wake up the virus” and boost the immune system’s ability to eliminate it once it’s flushed out of hiding.

 

Diaz said;

 

“We can’t search the entire body, but by the best evidence, we do not have infected cells.

“I think it’s very promising. This patient might be cured, but it will take more time to know.”

 

Professor Sharon Lewin, an HIV and infectious diseases expert at the University of Melbourne who was not involved in the research, said the fact that the patient has no antibodies was significant.

 

She said;

 

“When someone is infected with a virus they make antibodies. And antibodies don’t budge, even when you’re on treatment and there’s no detectable viral load. But this showed he had no antibodies which is supportive of him being cured.

“It’s interesting, but it’s hard to know how significant it is when it’s just a single case. I’d also like to know what happened to the other patients.”

In the past five years, after undergoing high-risk stem cell bone marrow transplants to treat cancer, only two people known as “Berlin” and “London” patients seem to have been cured of the disease.

Since the AIDS epidemic started in the 1980s more than 75 million people have been infected. The virus also caused 33 million deaths

Australia’s second-largest city, Melbourne heads back into Coronavirus lockdown

Australia's second-largest city, Melbourne heads back into Coronavirus lockdown

Nearly five million Melbourne residents were forced back into another lockdown after Coronavirus cases spiked on Tuesday, July 7, in Australia’s second-largest city.

All in Melbourne will be required to stay home from midnight on Wednesday, July 8, unless they go to work , study, shop for food or attend medical appointments. Restaurants, cafes and bars can only have delivery service, gyms and hair salons are closed, family events are restricted to two persons and the existing school holidays are extended.

Victoria state prime minister Daniel Andrews declared a six-week freeze, saying the virus crisis is over “we can’t pretend.”

After 191 of the 199 new cases recorded nationally on Tuesday were identified by the south-east region, the largest one-day increase since early April, Andrews said there were now too many to track properly, so restrictions were required.

“Those are numbers that are unsustainably high,” he said. “No-one wants to be in this place. I know there will be massive quantities of harm that will be caused because of this.

“We need to be transparent to one another that this is not over,” said Andrews. “And pretending it’s because we just want it to be over isn’t the solution. It’s actually part of the problem. A very big part of the issue.”

The decision was taken hours before it was expected for the first time in a century to close the busy border between Victoria and New South Wales.

Nearly 9,000 cases of COVID-19 and 106 deaths from the virus were reported in Australia.
