Researchers found that acupuncture treatment reduced the number of structural abnormalities in sperm and increased the overall number of normal sperm in a group of men with infertility problems.
They say the results suggest that acupuncture may complement traditional infertility treatments and help men reach their full reproductive potential.

Acupuncture May Ease Male Infertility
The male partner is a factor in up to 50% of infertile couples, write the researchers. In many cases, the cause of male infertility is unknown.
Previous studies of acupuncture and male infertility have suggested that acupuncture can improve sperm production and motility and count.
In this study, researchers looked at the effects of acupuncture on the structural health of sperm in men with infertility of unknown cause. The findings appear in the July issue of Fertility and Sterility.
Twenty-eight infertile men received acupuncture treatments twice a week for five weeks, and 12 received no treatment and served as a comparison group.
Researchers analyzed sperm samples at the beginning and end of the study and found significant improvements in sperm quality in the acupuncture group compared with the other group.
Acupuncture treatment was associated with fewer structural defects in the sperm and an increase in the number of normal sperm in ejaculate.
But other sperm abnormalities, such as immature sperm or sperm death, were unaffected by acupuncture.
The researchers write that acupuncture treatment is a simple, noninvasive method that can improve sperm quality.

Male Contribution to Viable Embryo

Centriole definition: a structure found in the cell cytoplasm (cytoplasm: all of the contents outside of the nucleus and enclosed within the cell membrane of a cell) that plays a role in embryo development.


Sperm centrioles were traced from fertilization to the hatching blastocyst stage. The sperm centriole is introduced into the egg at fertilization. As the male and female aspects of the developing embryo (called pro nuclei) fuse (called syngamy) to become a shared environment of both male and female DNA, centrioles play a pivotal role in cell division (cleavage) of the embryo.

This division, when the embryo goes from a single cell organism to a two cell organism to a four cell organism to an eight cell organism to a sixteen cell organism is called mitosis or cleavage. Sperm centrioles were detected at all stages of embryonic cleavage from the 1-cell through 8-cell stages, right up to the hatching blastocyst stage.

It is evident that the sperm centrosome ( formed from centrioles and having to do with cell division) is the functional active centrosome in humans, while the female is inactive.

Did you know? Embryos having 7-9 cells on day 3 have an increased chance of developing to the blastocyst stage. A blastocyst is a 5 day embryo and is considered to be of significant quality. Embryos with <7 cells or >9 cells are less likely to make it to the blastocyst stage.

My question is this: if a woman consistently produces 4 or 6 cell embryos during a stimulated IVF cycle is it not possible that the male partner’s sperm has some ultra structural defect whereupon centriole quality is subfunctional?

Since we know that the male contribution of healthy centrioles is necessary to facilitate cleavage of embryos to the blastocyst stage, it is my ardent recommendation that male partners of all women who are trying to conceive should also be treated with acupuncture and herbs. Even when the male partner presents within the normal range for volume, count, morphology and motility, centriole health cannot be easily determined.

Case: A female patient has 15 eggs retrieved during an IVF cycle; 10 fertilize, and 7 survive. She has 7, day 3 embryos ranging in size from 6 to 10 cells with zero fragmentation and a healthy10mm endometrial lining. The reproductive endocrinologist transfers three of these beautiful embryos and the cycle fails. Why? We do not know for sure: it could be that the embryos were chromosomally abnormal. This can be due to chromosomally abnormal eggs or sperm. It can also be due to the fact that the male centriole health and function were not optimal. This may be considered a ‘hidden’ cause of infertility.

The use of acupuncture and certain herbal medicines can vigorously stimulate blood flow to the testicles carrying oxygen and nutrients, as well as hormones from the brain, as well as electrolytes, while simultaneously carrying debris or dead cells away from the testicles. This increased delivery of the ‘good’ and increased excretion of the ‘bad’ may improve ultra structural properties of the sperm including centriole quality and function and thereby improve embryo quality and help facilitate cleavage to the blastocyst stage and thereby potentiate take home baby rates.

Summary: It is my opinion, based on clinical experience, that both partners should be treated with acupuncture and herbal medicine when wishing to start or grow a family and is having difficulty doing so.

Rising infertility in men linked to pollution

Published in: Legalbrief Environmental
Date: Tue 22 June 2010

Issue No: 0168


The Cape Argus notes that there is growing concern that environmental pollution may be behind increasing male infertility.

The Southern African Society for Reproductive Medicine and Gynaecological Endoscopy is compiling data from all the fertility clinics throughout the country. Dr Klaus Wiswedel, of the Cape Fertility Clinic, said they were seeing 1 200 to 1 500 male patients a year. A list of harmful pollutants that carried a risk for sperm production included an increase of lead and toxic fumes in the atmosphere, xeno-oestrogens (female hormones of plant origin) in factory-produced meats and chicken, plus an increase in the use of pesticides such as organophosphates (most of which are outlawed globally but still used here) and use of plastic wrappings. Puberty was another time when males were vulnerable to these environmental factors, the report quotes Wisdewel as saying.

Daily sex helps to reduce sperm DNA damage and improve fertility

Published: Tuesday, June 30, 2009 - 08:38 in Health & Medicine

Amsterdam, The Netherlands: Daily sex (or ejaculating daily) for seven days improves men's sperm quality by reducing the amount of DNA damage, according to an Australian study presented today (Tuesday) to the 25th annual meeting of the European Society of Human Reproduction and Embryology in Amsterdam.

Until now there has been no evidence-based consensus amongst fertility specialists as to whether or not men should refrain from sex for a few days before attempting to conceive with their partner, either spontaneously or via assisted reproduction.

Dr David Greening, an obstetrician and gynaecologist with sub specialist training in reproductive endocrinology and infertility at Sydney IVF, Wollongong, Australia, said: "All that we knew was that intercourse on the day of ovulation offered the highest chance of pregnancy, but we did not know what was the best advice for the period leading up to ovulation or egg retrieval for IVF.

"I thought that frequent ejaculation might be a physiological mechanism to improve sperm DNA damage, while maintaining semen levels within the normal, fertile range."

To investigate this hypothesis, Dr Greening studied 118 men who had higher than normal sperm DNA damage as indicated by a DNA Fragmentation Index (DFI). Men who had a more than 15% of their sperm (DFI >15%) damaged were eligible for the trial. At Sydney IVF, sperm DNA damage is defined as less than 15% DFI for excellent quality sperm, 15-24% DFI for good, 25-29% DFI for fair and more than 29% DFI for poor quality; but other laboratories can have slightly different ranges.

The men were instructed to ejaculate daily for seven days, and no other treatment or lifestyle changes were suggested. Before they started, levels of DNA damage ranged between 15% and 98% DFI, with an average 34% DFI when measured after three days' abstinence. When the men's sperm was re-assessed on the seventh day, Dr Greening found that 96 men (81%) had an average 12% decrease in their sperm DNA damage, while 22 men (19%) and an average increase in damage of nearly 10%. The average for the whole group dropped to 26% DFI.

Dr Greening said: "Although the mean average was 26% which is in the 'fair' range for sperm quality, this included 18% of men whose sperm DNA damage increased as well as those whose DNA damage decreased. Amongst the men whose damage decreased, their average dropped by 12% to just under 23% DFI, which puts them in the 'good' range. Also, more men moved into the 'good' range and out of the 'poor' or 'fair' range. These changes were substantial and statistically highly significant.

"In addition, we found that although frequent ejaculation decreased semen volume and sperm concentrations, it did not compromise sperm motility and, in fact, this rose slightly but significantly.

"Further research is required to see whether the improvement in these men's sperm quality translates into better pregnancy rates, but other, previous studies have shown the relationship between sperm DNA damage and pregnancy rates.

"The optimal number of days of ejaculation might be more or less than seven days, but a week appears manageable and favourable. It seems safe to conclude that couples with relatively normal semen parameters should have sex daily for up to a week before the ovulation date. In the context of assisted reproduction, this simple treatment may assist in improving sperm quality and ultimately achieving a pregnancy. In addition, these results may mean that men play a greater role in infertility than previously suspected, and that ejaculatory frequency is important for improving sperm quality, especially as men age and during assisted reproduction cycles."

Dr Greening said he thought the reason why sperm quality improved with frequent ejaculation was because the sperm had a shorter exposure in the testicular ducts and epididymis to reactive oxygen species – very small molecules, high levels of which can damage cells. "The remainder of the men who had an increase in DFI might have a different explanation for their sperm DNA damage," he concluded.

Study Shows Alternative Treatment May Help Male Infertility Problems

Aug. 3, 2005 -- Acupuncture may help some men overcome infertility problems by improving the quality of their sperm, according to a new study.
