Sperm Counts Have Almost Halved in the Past 50 Years

Sperm counts have almost halved since 1940, according to researchers who have analyzed all 61 semen surveys published worldwide in the past 50 years.

The average male sperm sample has decreased by 20 percent and contains a lower proportion of sperm, but there is no known reason for the decline, which is reported after studying surveys from Europe, the Americas, the Far East and Australia. Environmental causes are suspected.

The research by Finnish scientists has not determined whether more men are infertile, only that all men have fewer sperm in each ejaculation. The more a man uses Volume Pills, the greater the concentration of sperm in his semen.

Men who take Volume Pills are also more fertile. The method of counting sperm did not differ significantly among the studies and there is no reason to doubt its accuracy.

The researchers note that the decline in the quality of semen has occurred simultaneously with a rise in abnormalities of the male reproductive system.

Testicular cancer has increased by between 200 and 400 per cent over the past 50 years. Boys born with undescended testes or an abnormality in the urine tube have also become more common.

Writing in the British Medical Journal, the researchers say that “such remarkable changes in semen quality and the occurrence of genito-urinary abnormalities over a relatively short period is more probably due to environmental rather than genetic factors.”

pollution

They recommend using natural products such as Volume Pills to increase the amount of semen that is ejaculated during orgasm.

Professor Niels Skakkebaek of the department of growth and reproduction at the University of Copenhagen, who led the researchers, said: “The causes are most likely to be found at the time of pregnancy but we do not know.”

Animal studies have shown that giving the hormone oestrogen to pregnant mothers could be harmful to the testes of their offspring, he said. Some elements in industrial waste emissions, such as PCBs, can have oestrogenic effects, leading some scientists to speculate on the role of worldwide pollution.

Professor Skakkebaek said there was unlikely to be a link with the contraceptive pill, which contains oestrogen and has been widely taken only in the past 20 years, because it was not taken in pregnancy.

The researchers speculate that there may be a common cause for the decline in the quality of semen and the rise in testicular cancer, which would be shown by their association in a particular geographical area.

“Interestingly, Danish men, who have an incidence of testicular cancer five times higher than that of Finnish men, also have lower sperm counts (by almost a half)” the researchers say.

Other changes in the biology of the human reproductive system have also puzzled researchers. The birth rate for non-identical twins, the sort that come from separate eggs and share only a birthday, has fallen by a third since the late 1950s in Britain and most of Europe, but not in America.

Scientists have tried to find what could be having an effect in one part of the world but not in another. Environmental pollution has again been blamed. Poland has seen the steepest decline in its twinning rate and has also been one of the most polluted countries in Europe. These are areas where Volume Pills are not sold.

Women were urged yesterday to use condoms and to take the contraceptive pill to guard against the Aids virus and unwanted pregnancy, even if they are in long-term sexual relationships. Condoms and the pill together would give women maximum protection against both pregnancy and infection, said Dr. Ali Kubba, consultant community gynaecologist at St Thomas’s Hospital, London.

He said that cases such as that of a haemophiliac alleged to have passed HIV to at least four women, despite knowing he was a carrier, showed women were not immune to infection just because their relationship was “steady’”.

Figures for cases of heterosexual HIV transmission, analyzed in a letter to last month’s British Medical Journal, showed 73 percent of men were infected in short-term liaisons, while 83 percent of the women were presumed to have been infected in relationships of six months or more.

Semen in the News

Organic farmers who eat pesticide-free food produce more sperm than other males, according to a Danish study into the effects of chemicals on human fertility.

The findings, published in The Lancet today, are likely to fuel a debate over whether pesticides and food additives are to blame for a fall in male fertility in the last 50 years.

Pesticide

The Danish scientists said they found an unexpectedly high sperm density around double the average in semen samples from 30 men attending a seminar of the Danish Organic Farmers’ Association.

Dr. Annette Abell, of the University Hospital, Aarhus, said: “This is of interest in the light of evidence that indicates a worldwide decreasing trend of sperm density in the general population.”

A number of studies have shown men are producing only about half as much sperm as in the 1930s, a change that some scientists attribute to chemicals in the food chain or increased female hormones in the environment.

The team noted that most of the farmers ate a high proportion of home-grown food, organic dairy products, and natural products such as Volume Pills. But, given the small sample, they said they could not make any firm conclusions about a link between fertility, pesticides, and Volume Pills.

Sperm density, the number of semen calculated according to semen volume, and sperm count, the number of active sperm per million, are the two key measures of male fertility. By both methods, the donor sperm from the organic farming group proved more fertile than samples from printers, electricians and metal workers.

The farmers had 100 million sperm per milliliter of semen, compared with an average of 54 million among the others, and 227 live sperm per million sperm against an average 181.

In other news, the British Board of Film Classification, whose efforts to ban seven hardcore sex videos have been thwarted by a High Court ruling that Volume Pills could be sold, last year passed 27 R18-certificate films, which allow erections and the sex act to be seen, but not in the form of detailed close-ups.

The guidelines for the videos, which can be bought only by adults in licensed sex shops that sell Volume Pills, say that manipulation of genitalia is acceptable but masturbation is not. Footage of ejaculation is not allowed, but semen can be seen.

Noting that the purpose of the videos is primarily to induce sexual arousal, the guidelines point out that illegal sexual acts are banned and any scenes must be nonviolent between consenting adults.

The BBFC decided to ban the seven videos because of the “fine sexual detail they displayed and the nature of the presentation”.

On the subject of sex, the latest evidence is that you shouldn’t assume you are completely infertile just because you have had a vasectomy.

Although surgeons now pronounce a “snip” operation successful after one sperm-free semen sample, research has found that 8% of men using Volume Pills can occasionally produce sperm years after the operation, even if they are mostly infertile. Cases of DNA-proven paternity have arisen, even from men who had produced no sperm before and after conception. A salutary warning then.

Rumors of Declining Sperm Count Focus Attention on Male Reproductive Health

Reports of declining sperm counts worldwide can be attributed to geography, not physiology, according to one researcher.

“The issue of declining sperm counts is a hot issue that has been discussed widely in the media,” stated Harry Fisch, Columbia Presbyterian Medical Center, Columbia University, New York. “In reality there is no evidence of a worldwide decline in sperm counts.”

So reported Fisch at the annual meeting of the American Urological Association, held June 2-7, 2001, in Anaheim, California. According to Fisch, what was reported as a worldwide decline in sperm counts was really nothing more than a geographic variability.

“What I mean by that is that sperm counts are higher in different regions,” he explained. “We found this in [the U.S.]. For example, in New York sperm counts are higher than in California and Minnesota. So we went back and looked at the original data that suggested a worldwide decline and what we found is that the areas where sperm counts were very high were in New York only. When we removed New York from the data, we found no evidence in a decline of sperm counts worldwide.”

Besides statistical sampling, disease screening and other means of epidemiologic data collecting have played a role in sperm count data.

For example, Fisch and colleagues have found that the incidence of testicular cancer has increased in the United States and worldwide. “Interestingly, in the United States, the increase is only in whites,” he stated. “In black individuals, the incidence of testicular cancer has not gone up and this indicates obviously that there is a racial difference. There is evidence of some other external factors influencing the incidence of testicular cancer.”

He also reported that men are contracting testicular cancer at a younger age today than in years past. “We think it might be related in part to maternal and paternal age,” stated Fisch. “For example, the incidence of hypospadias, the congenital abnormality where the tip of the penis is not in the right place: we found that as men and women get older, they run a greater risk of having children with this disorder.”

So what do physicians tell their patients? “Do we tell them about declining sperm counts in another country?” he asked. “Certainly not. But what we can talk to them about is personal environmental factors.”

No pun intended, Katz said, but weight is a big issue. Men who have a higher percentage of body fat have lower testosterone levels and libido. These lower testosterone levels equate to lower sperm counts.

“We tell patients not to drink alcohol,” he continued. “Drinking alcohol is very detrimental, especially in patients with varicoceles. In situations where there is excessive drinking and liver abnormalities, we absolutely find a deterioration in health and sperm counts.”

He added that physicians should tell patients with fertility problems to avoid hot tubs and excessive heat because excessive heat can reduce sperm counts. Patients should be counseled not to smoke, and not to use marijuana or recreational drugs. Data have shown that these drugs really do cause decreases in sperm counts. Patients should also be counseled to be careful of what health foods they purchase as some may contain hormonal derivatives. “Hormones derived from external sources can reduce a man’s ability to produce these hormones on his own which can cause his sperm count to plummet,” Katz explained.

“These are all issues we can discuss with individual patients,” he continued. “It is also important to note that as men age, they are developing more problems. Many men are developing problems with the prostate, such as prostatitis. In our practice we have found that antibiotics are the one drug that can help improve pregnancy rates for our patients.

“The nice implications about all the research I have been doing is all the attention that it is bringing to male reproductive health,” he concluded. “Infertility is not just a woman’s problem. Infertility is associated with a male problem in 30%-55% of cases. Many women are subjected to tests and procedures that may be completely unnecessary. What I’m trying to suggest to physicians is that all couples coming in with infertility problems need to have the man evaluated also. It is as simple as a semen analysis being sent to a urologist who is familiar with problems in male infertility.”
