Does IUI technique matter?

When sperm wash techniques were first developed with a medium called Ham’s F10 artifical insemination was revolutionized. Prior to that time all that was available was cup insemination (ICI) or injection into the cervical mucus which itself was often the problem. Over the years culture media has vastly improved but the technique of actually performing the procedure was relatively standard …

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 …

Obesity Can Hurt Male Fertility

A new study by researchers in India is showing that obesity can hurt male fertility.  Researchers at a fertility center in India analyzed sperm samples from over 1200 men and found that men who were obese (body mass index greater than 30) had lower semen volumes, lower sperm counts, lower sperm motility, and a higher percentage of abnormally shaped sperm.  …

New Fathers’ Age is Rising

Maybe this is why we are seeing more cases of male infertility and many cases of IVF are requiring ICSI.

Researchers at Stanford University reviewed data on 168,867,480 live births from 1972 to 2015, making statistical adjustments for missing paternal records. The average age of the father of a newborn in the United States, the investigators found, has risen to …

Common Household Products May Reduce Fertility

A new study is showing that ingredients in common household products may reduce fertility.  Researchers from University of California, Davis found that quaternary ammonium compounds, also known as “quats”, inhibit mitochondria and estrogenic functions in cells that were studied in vitro.

Quats are used as antimicrobial agents in many common household products, including antiseptics in toothpastes, mouthwashes, shampoos, lotions, household …

Quiet bedroom= stronger sperm

Last week Dr Amin blogged here that a new analysis published in the journal, Human Reproduction Update, is showing that the sperm counts of men in North America, Europe, Australia, and New Zealand have markedly declined in the past 40 years.

If you or your partner has a marginal sperm count, here is something simple that could make a …

Sperm Counts of Western Men are Declining

A new analysis published in the journal, Human Reproduction Update, is showing that the sperm counts of men in North America, Europe, Australia, and New Zealand have markedly declined in the past 40 years.

Researchers from the Hebrew University of Jerusulem conducted a meta-analysis of 185 studies. The studies included data from sperm samples from almost 43,000 men from …

Caffeine May Affect Male Fertility

A new study is showing that excessive caffeine intake may affect male fertility.  The study by Italian researchers, published in Nutrition Journal, showed that increased caffeine intake may affect male reproductive function, possibly through sperm DNA damage.

The study compiled data from approximately 20,000 males involved in 28 previous research studies that looked at the relationship between male coffee/caffeine …
