Vandenbergh effect

Index Vandenbergh effect

The Vandenbergh effect is a phenomenon reported by J.G. Vandenbergh et al. in 1975, in which an early induction of the first estrous cycle in prepubertal female mice occurs as a result of exposure to the pheromone-laden urine of a sexually mature (dominant) male mouse. [1]

Androgen

An androgen (from Greek andr-, the stem of the word meaning "man") is any natural or synthetic steroid hormone which regulates the development and maintenance of male characteristics in vertebrates by binding to androgen receptors.

Bruce effect

The Bruce effect, or pregnancy block, is the tendency for female rodents to terminate their pregnancies following exposure to the scent of an unfamiliar male.

Castration

Castration (also known as gonadectomy) is any action, surgical, chemical, or otherwise, by which an individual loses use of the testicles.

Estradiol

Estradiol (E2), also spelled oestradiol, is an estrogen steroid hormone and the major female sex hormone.

Estrous cycle

The estrous cycle or oestrus cycle (derived from Latin oestrus 'frenzy', originally from Greek οἶστρος oîstros 'gadfly') is the recurring physiological changes that are induced by reproductive hormones in most mammalian therian females.

Exogeny

In a variety of contexts, exogeny or exogeneity is the fact of an action or object originating externally.

Gonadotropin-releasing hormone

Gonadotropin-releasing hormone (GnRH) also known as gonadoliberin, and by various other names in its endogenous form and as gonadorelin in its pharmaceutical form, is a releasing hormone responsible for the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the anterior pituitary.

Pheromone

A pheromone (from Ancient Greek φέρω phero "to bear" and hormone, from Ancient Greek ὁρμή "impetus") is a secreted or excreted chemical factor that triggers a social response in members of the same species.

Treatment and control groups

In the design of experiments, treatments are applied to experimental units in the treatment group(s).

Tritium

Tritium (or; symbol or, also known as hydrogen-3) is a radioactive isotope of hydrogen.

Uterus

The uterus (from Latin "uterus", plural uteri) or womb is a major female hormone-responsive secondary sex organ of the reproductive system in humans and most other mammals.
