Male Infertility

Causes of Male Infertility

Infertility is a reproductive system disorder which results in the inability of a couple to procreate. The reasons for not being able to conceive can be varied and could be related to either partner. When the reproductive system of the male has a problem which makes it difficult for the couple to have a child, it is termed male infertility.

Study sheds new light on impact of common plasticizer on human reproductive health

Researchers at Harvard Medical School and the New York State Department of Health have discovered how a common plasticizer associated with human reproductive abnormalities likely does its damage at the molecular level.

Cystic fibrosis carriers have higher risk for all CF-related conditions

Conventional wisdom says that having just one mutated copy of the cystic fibrosis gene has no effects on a person's health--the disease occurs when both copies of the gene are mutated. But a new study from the University of Iowa suggests that may not be the case.

Zinc and folic acid supplements fail to improve fertility in men

Zinc and folic acid, a pair of dietary supplements long touted as an effective treatment for male infertility, failed to improve pregnancy rates, sperm counts, and sperm potency in a new study conducted at University of Utah Health and other medical centers in conjunction with the National Institutes of Health.

Penn researchers track defective sperm epigenome linked to male infertility

One out of eight couples has trouble conceiving, with nearly a quarter of those cases caused by unexplained male infertility. For the past decade, research has linked that infertility to defective sperm that fail to "evict" proteins called histones from DNA during development.

Important discovery about male infertility could lead to new treatments

Using a new mouse model, Penn Medicine researchers have identified defects in the sperm epigenome that cause male infertility.

Why some sperm swim in circles – it’s a protein defect

A new study published in the journal PNAS shows that some sperm cannot swim straight because they lack a protein called VSP. This motility defect seriously impacts the rates of successful fertilization. In addition, VSP is also found to regulate the amount of calcium that enters the flagellum, the whiplike organelle that propels the sperm towards the waiting ovum or egg. This important discovery may help treat infertility more effectively.

Researchers discover genes linked to sex ratio and male fertility in mice

One of the more recent trends among parents-to-be is the so-called gender reveal, a party complete with pink or blue cake to answer the burning question, "Is it a boy or girl?" After all, it's presumed that there's a 50-50 chance you'd have one or the other.

Father’s nutritional pattern affects child’s cardiovascular health

While couples often change their lifestyle in order to conceive faster, including crash diets, a new study in mice throws up the possibility that this kind of extreme dietary modification by the father might result in adverse effects on the child conceived in this manner.

Study highlights potential impact of chlamydia infection on men's fertility

The potential impact of undiagnosed sexually transmitted chlamydia infection on men's fertility has been highlighted in a study led by Queensland University of Technology (QUT), which for the first time found chlamydia in the testicular tissue biopsies of infertile men whose infertility had no identified cause.
