Regulation of ovulation by human pheromones
Article Abstract:
A study looked at whether humans produces compounds regulating a specific neuroendocrine mechanism in other people without being consciously detected as odours. Odourless compounds from the armpits of women in the late follicular phase of their menstrual cycles were found to accelerate the preovulatory surge of luteinizing hormone of recipient women, shortening their menstrual cycles. Axillary compounds from the same donors collected later in the menstrual cycle were found to delay the luteinizing-hormone surge and lengthen the menstrual cycle.

Marine gamete-release pheromones
Article Abstract:
Uric acid and inosine are identified as the sperm-release pheromone of Platynereis dumerilii and egg-release pheromone of Nereis succinea, respectively. The sex pheromones contain the purine ring system so far unidentified in any species. The threshold concentration of the sperm-release pheromone in P. dumerilii is 0.6 micromol. On dissolving the amount of uric acid present in the coelomic fluid of one female, there is a five-fold concentration increase ensuring fertilization. Both uric acid and inosin are species- and sex-specific.

Autocrine mitogenic activity of pheromones produced by the protozoan ciliate Euplotes raikovi
Article Abstract:
The autocrine stimulation activities of Euplotes raikoviphermones result in selective cell growth and intracellular collaboration, indicating that these processes predate multicellular life. The pheromones appear necessary for expansion and viability as mutant cells without pheromones were not viable. Mitogenic proliferation of the same cells from which the pheromones originated is promoted by the pheromones.
