Study reveals how a key spinal circuit shapes the choreography of sex

For decades, it was thought that while the brain orchestrated male sexual behaviour – arousal, courtship, and copulation – the spinal cord merely executed the final act: ejaculation.

Loss of key Y chromosome gene causes infertility in male mice

In a new study conducted at the University of Hawaiʻi at Mānoa, researchers from the John A. Burns School of Medicine (JABSOM) have shown that the loss of a key male fertility gene leads to infertility and changes expression of hundreds of other important genes.

Common bladder infection may signal urogenital cancer risk

A bout of the common bladder infection, cystitis, may signal the presence of urogenital cancers-which affect parts of the body involved in reproduction and excretion-in middle aged adults, suggests research published in the open access journal BMJ Public Health.

Bacteria use density switch to balance virulence and growth

Pathogens are becoming more and more resistant to antibiotics. With the goal of developing new therapeutic approaches to treat bacterial infections more effectively in the future, researchers at the Karlsruhe Institute of Technology (KIT) and the Max Planck Institute in Marburg investigated the plague-related bacterium Yersinia enterocolitica.

Can cannabis use disrupt women’s fertility? New study finds strong evidence

Researchers found that THC, the psychoactive compound in cannabis, alters oocyte gene expression, spindle formation, and chromosome segregation, lowering embryo euploidy rates in IVF. This provides direct human evidence linking cannabis exposure to impaired female fertility outcomes.

Study maps gene activity across pregnancy breastfeeding and post-weaning stages

In a study in mice, researchers have identified genes associated with the dramatic transformation of the mammary gland in pregnancy, breastfeeding, and after breastfeeding as it returns to its resting state.

Exosomes carry key indicators of biological aging

A new research paper featured on the cover of Volume 17, Issue 8 of Aging (Aging-US) was published on July 30, 2025, titled "Exosomes released from senescent cells and circulatory exosomes isolated from human plasma reveal aging-associated proteomic and lipid signatures."

New technique succeeds in studying embryo implantation outside the body

The use of assisted reproductive technologies like in vitro fertilization is becoming more common worldwide. However, while these technologies successfully create viable embryos, a little over half of all embryos are lost because they fail to implant into the uterus.
