Seminal fluid harbours the as yet unknown mechanism that facilitates rapid adjustment of sperm velocity in response to changing sperm competition risk.

A change in social status can quickly lead to a change in the quality of the seminal fluid produced by a male Chinook salmon as he responds to increased reproductive competition from higher-status males.

A high-throughput phenotypic human sperm screening platform was developed which allows for major drug discovery programmes for male contraception.

TMEM95, a protein localized to the sperm acrosome cap, is essential for fertilization.

A new tool to visualize blood-feeding mosquitoes in high resolution and quantitatively characterize their behavior sheds light on contact-dependent sensing and blood-feeding dynamics of several medically relevant mosquito species.

The molecular identity of the temperature-sensitive ion channel of human sperm that ensures depolarization is TRPV4.

Reproductive fluids help the correct establishment of some epigenetic marks and gene expression in preimplantation pig embryos.

Nematode sperm respond to competitive environments by modulating cellular pathways involved in migration and storage to ensure their access to oocytes.

A protein called SIR-2.1 helps to protect worms from the effects of aging by regulating metabolic processes that would otherwise generate damaging reactive oxygen species.

A novel developmental mechanism generates a previously undescribed pair of sex-specific proprioceptive neurons required for male-specific behaviour.
