New measure of sperm age may predict pregnancy success
A novel technique to measure the age of male sperm has the potential to predict the success and time it takes to become pregnant, according to a newly published study by researchers at the Wayne State University School of Medicine. … Continue reading
High BMI linked to sperm cell irregularities
Single-cell analysis of autopsied human testes suggests that abnormalities associated with aging sperm cells might be exacerbated by elevated body mass index (BMI). The research appears in the journal Developmental Cell. Even though it is well established that older men display … Continue reading
COVID-19 alters levels of fertility-related proteins in men, study suggests
Many people who recover from COVID-19 experience long-term symptoms, such as brain fog or heart problems. Increasing evidence suggests that the virus can also impair fertility. Now, researchers at the Indian Institute of Technology have analyzed protein levels in semen … Continue reading
COVID-19 may impact male fertility, study finds
Severe cases of COVID-19 might harm the quality of a man’s sperm and possibly impact his fertility, according to a recent study published in the journal Reproduction. “This report provides the first direct evidence to date that COVID-19 infection impairs … Continue reading
Father’s health a factor in pregnancy loss, study finds
A father who is in bad health before conception may increase the odds for pregnancy loss, a new study in the journal Human Reproduction reports. Researchers looked at data on 958,804 pregnancies between 2007 and 2016, and correlated that with … Continue reading
Researchers reveal why heat stress damages sperm
University of Oregon biologists have used the model organism Caenorhabditis elegans to identify molecular mechanisms that produce DNA damage in sperm and contribute to male infertility following exposure to heat. In humans, the optimal temperature for sperm production is just … Continue reading
Sperm quality lowered by light from devices at night
Men might want to think twice before reaching for their smartphone at night. A new study found correlations between electronic media use at night and poor sperm quality. Preliminary results show that greater self-reported exposure to light-emitting media devices in … Continue reading
Lab-grown sperm could let infertile men have children
Infertility affects one in seven men of reproductive age worldwide. One idea for treating male sterility is spermatogonial stem cell (SSC) therapy. In this approach, sperm stem cells in the testis are transferred to a test tube, cultured and nudged … Continue reading
Diet has rapid effects on sperm quality
Sperm are influenced by diet, and the effects arise rapidly. This is the conclusion of a study by researchers at Linköping University, in Sweden, in which healthy young men were fed a diet rich in sugar. The study, published in PLOS … Continue reading
Chlamydia affects men’s fertility too, research finds
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 … Continue reading
