Kiwi men on track to have zero viable sperm by 2040 - scientist

A scientist studying human fertility has warned Kiwi men's sperm counts are dropping so rapidly, within a couple of decades there might be none left.

In 2017, Shanna Swan - an epidemiologist at Icahn School of Medicine at Mount Sinai, New York - co-authored research looking at falling sperm counts in New Zealand, Australia, Europe and North America.

Looking at 185 studies dating back to 1973, Dr Swan and her team found a 50-60 percent decline between 1973 and 2011.

It was sparked by a paper she saw while on sabbatical.

"I spent six months... looking in detail to see, was this decline due to different method of measuring sperm, or recruiting men, or where they more obese or did they smoke more?" she told Environmental Health News this week, promoting the release of her new book Count Down: How Our Modern World Is Threatening Sperm Counts, Altering Male and Female Reproductive Development, and Imperiling the Future of the Human Race.

"Were there other things that could explain the decline? After six months of work, the answer was no. The slope had not changed after all that analysis."

So she started the proper research that would result in the shocking 2017 paper published in journal Human Reproduction Update - which found the decline was indeed real, consistent and showing no signs of slowing down.

Dr Swan says at current trends, it's on track to hit zero between 2040 and 2045.

"What does that mean? These are median sperm counts - which means half the men in Western countries will have no sperm. This is a big problem, if it were to come to that... If things continue in the same way, it looks very grim for our population survival."

Similar drops in sperm quantity weren't seen in men from South America, Asia and Africa - the scientists unsure whether that was significant, or just because they didn't have enough data from those regions.

So what's behind the drop in Western men's virility? The initial study didn't go into that, but she does in the book.

"I think everyone agrees this is not genetics - this is too fast for an evolutionary change, we're talking about 40 or 50 years," she told Environmental Health News, saying that environmental and lifestyle factors are likely to blame - including the effects of pesticides, cosmetics, foam furniture, paper plates, work stress, fatty food, processed food and packaging.

"The chemicals I'm particularly interested in... are those that affect the body's hormones. The reason is that reproduction depends on healthy hormones. Anything that would interfere with the body's natural hormone system... is going to challenge the reproductive system."

"If women want to have a baby, they are often told, 'Clean up your act,' " Dr Swan writes in the book. "But it's probably more important for men to do so."

About The Book
In the tradition of Silent Spring and The Sixth Extinction, an urgent, meticulously researched, and groundbreaking book about the ways in which chemicals in the modern environment are changing—and endangering—human sexuality and fertility on the grandest scale, from renowned epidemiologist Shanna Swan.

In 2017, author Shanna Swan and her team of researchers completed a major study. They found that over the past four decades, sperm levels among men in Western countries have dropped by more than 50 percent. They came to this conclusion after examining 185 studies involving close to 45,000 healthy men. The result sent shockwaves around the globe—but the story didn’t end there. It turns out our sexual development is changing in broader ways, for both men and women and even other species, and that the modern world is on pace to become an infertile one.

How and why could this happen? What is hijacking our fertility and our health? Count Down unpacks these questions, revealing what Swan and other researchers have learned about how both lifestyle and chemical exposures are affecting our fertility, sexual development—potentially including the increase in gender fluidity—and general health as a species. Engagingly explaining the science and repercussions of these worldwide threats and providing simple and practical guidelines for effectively avoiding chemical goods (from water bottles to shaving cream) both as individuals and societies, Count Down is at once an urgent wake-up call, an illuminating read, and a vital tool for the protection of our future.

Singapore's total fertility rate falls to historic low in 2020
www.channelnewsasia.com

​

SINGAPORE: Singapore's total fertility rate (TFR) fell to a historic low of 1.1 last year, said Minister in the Prime Minister's Office (PMO) Indranee Rajah on Friday (Feb 26).

She said that the COVID-19 pandemic caused some Singaporeans to postpone their marriage, resulting in about 10 per cent fewer marriages last year than in 2019. Others have delayed their parenthood plans, she added.

Ms Indranee, who oversees the National Population and Talent Division under the PMO, was speaking in Parliament during the Committee of Supply debate.

East Asian societies like South Korea and Taiwan, as well as Scandinavian countries known for achieving good fertility outcomes like Finland and Norway also experienced a drop in TFR, she noted.

"Raising fertility is an uphill task for advanced societies, but we must continue to support those who wish to marry and have children," said Ms Indranee, who is also Second Minister for Finance and for National Development.

She announced during the debate that the Government will increase its dollar-for-dollar matching in the Child Development Account for a second child from S$3,000 to S$6,000.

TFR refers to the average number of live-births each woman would have during her reproductive years. The resident TFR has been gradually declining over the past decades and was 1.14 in 2019.

Ms Indranee also told MPs that Singapore will continue to "carefully calibrate" the pace of immigration.

In 2020, Singapore gained about 21,100 new citizens and 27,500 new permanent residents. These figures are lower than previous years due to travel restrictions and operational issues arising from COVID-19, she said.

For example, safe management measures resulted in limited slots to complete the final steps for PR and citizenship registration, which must be done in person. A few thousand applicants, who were approved in-principle, had not completed all the required processes to be granted their PR or citizenship by the end of 2020.

Depending on how the COVID-19 situation evolves, these applicants could be granted PR or citizenship in the coming months, and may add to the numbers normally granted this year, Ms Indranee said.

From June 2019 to June 2020, Singapore's total population declined slightly by 0.3 per cent due to a decrease in foreign employment in the services sector, and Work Permit Holders. S Pass and Employment Pass holders have also decreased amid the pandemic due to travel restrictions and the economic downturn.

"The Government continues to maintain a tight stance on our foreign worker manpower policy," she said.

Its probably due yo rugby

 

[nirvarq]

Wanna bet it'll go lower with vaccines and probably the only unaffected ones are the RH- Negative they're 15% of the world population. ie
1,170,000,000, one billion one hundred seventy million.

Guess who are the top people in the world are RH- ?

You 'monkeys' are expandable ! lol...........

 

[syed putra]

So no need to be vaccinated.

Research Highlight: BPA linked to infertility in women

​

BPA (Bisphenol-A) is a chemical compound found in many consumer products including polycarbonate plastics and epoxy resins used in food and drink packaging. However, evidence is accumulating that suggests that BPA may contribute to a variety of health problems. Because BPA has been shown to alter the function of the endocrine system, and has been detected in blood and urine of patients undergoing treatment for infertility, researchers suspect that it may interfere in some way with the normal reproductive cycle.
In an NIEHS Center funded pilot study, a group of researchers led by Center member Catherine Racowsky, asked the question, “Does exposure to bisphenol-A (BPA) impact fertility by affecting the maturation of human oocytes (eggs)?”
They conducted a randomized trial, using 352 clinically discarded oocytes from 121 patients undergoing infertility treatment at the Brigham and Women’s Hospital, exposing the oocytes to increasing levels of BPA in the laboratory.
They found that exposure to BPA caused a variety of problems with the normal development and maturation process of the eggs, leading to a reduction in the number of eggs that matured, and an increase in the number that degenerated or underwent abnormal activation.
Of the eggs that did mature, there was a significant trend toward malformation of the spindles, a structural part of the egg that is critically important for the proper alignment and separation of the chromosomes.
The investigators explained that “If the chromosomes do not separate correctly, then the egg will end up with either too many or too few chromosomes — in which case, generally speaking, if the egg fertilizes it will give rise to an embryo that isn’t capable of developing, or if it develops it will give rise to a chromosomally abnormal individual.”
These preliminary observations document for the first time the effect of BPA on oocyte meiotic maturation, spindle morphology and chromosome alignment in human oocytes. Taken together with a growing body of evidence regarding the negative health effects of BPA, this work brings us one step closer to understanding the impact of chemicals in our environment on the growing problem of human infertility.
