Prediabetes May Affect Male Fertility

A new study is providing more evidence that a man’s general health can affect his sperm quality.   The study, published in BJU International, found that infertile men with prediabetes have altered hormone levels and increased sperm DNA fragmentation compared to infertile men without prediabetes.

Researchers from the University Vita Salute San Raffaele in Milan, Italy, examined 744 men with …

Does Diet Affect Sperm Quality?

Multiple recent studies have shown a decline in men’s sperm concentration and total sperm count over the past 80 years, but the underlying cause of this downward trend is unclear.  Most likely, there are multiple factors contributing to this trend, including worsening diets and an increasing number of men with obesity.

A recent review in the journal Fertility and Sterility …

Advances in Male Fertility Testing

A new test developed by Androvia LifeSciences, called a Cap-Score, may help predict whether or not a man’s sperm is able to fertilize an egg.  The Cap-Score was developed by the Travis lab at the Baker Institute for Animal Health and Cornell University’s College of Veterinary Medicine, who recently published their Cap-Score data in the journal Molecular Reproduction and Development

Do Boxers or Briefs Matter?

A new study published in the journal Human Reproduction found that men who wear loose fitting underwear have better sperm counts and motility compared to men who wear tight fitting underwear.

Researchers from Harvard looked at the semen analyses of 656 male partners of couples seeking fertility treatment.   The men were all between 32 and 39 years old.  The type …

Moderate Alcohol Consumption May Improve Male Fertility

The question about whether or not alcohol consumption affects male fertility is difficult to answer because the medical literature in this area has been mixed.  A new study from Italy, published in the journal Andrology, is suggesting that a moderate amount of alcohol by men may actually boost male fertility.

The study looked at the semen analyses of 323 …

Low Sperm Count May Be a Marker of General Health

A new study presented at ENDO 2018, the Endocrine Society’s 100th annual meeting in Chicago, IL, found that low sperm count may not only be a problem for fertility, but is also a marker for a man’s general health.

The study looked at 5,177 male partners of infertile couples in Italy and found that low sperm counts were associated with …

Antihistamines May Affect Male Fertility

An Argentinian review of multiple animal studies is suggesting that antihistamines, found in common allergy medications, may affect male fertility.  The study, published in the journal Reproduction, found that antihistamine use could decrease sperm motility and alter sperm morphology.

The study found several papers that reported impaired testicular function in animal studies after antihistamine exposure.  These papers found that …

Ibuprofen May Affect Male Fertility

A new study, published in the journal Proceedings of the National Academy of Sciences, found that ibuprofen alters the endocrine system and has a negative impact on the testicles of young men.

The study looked at 31 men between the ages of 18 and 35.  Fourteen of these men were given 600 milligrams of ibuprofen twice a day.  The remaining …

Air Pollution May Cause Poor Sperm Quality

A new study published online in Occupational & Environmental Medicine, is suggesting that air pollution may be linked to poorer sperm quality.  The study showed that exposure to fine particulate matter air pollution is associated with a lower level of sperm normal morphology.

The study looked at the sperm concentration, motility, and morphology of approximately 6500 men, ages 15 …

When Should ICSI be Used?

Intracytoplasmic sperm injection (ICSI) is a very specialized technique performed by embryologists that involves injecting a single sperm into each egg retrieved from an IVF cycle.  It was first introduced in the early 1990s to help fertilize eggs for couples with male factor infertility.  Since the 1990s, the use of ICSI with IVF cycles has substantially increased.  In fact, ICSI …
