Due to the normal action of Müllerian inhibiting factor produced by the testes in utero, individuals with 5-ARD lack a uterus and Fallopian tubes.

* Müllerian inhibiting substance, a developmental glycoprotein

It has also been called Müllerian inhibiting factor ( MIF ), Müllerian-inhibiting hormone ( MIH ), and Müllerian-inhibiting substance ( MIS ).

* Müllerian inhibiting factor, a hormone that plays a role in the sexual differentiation of humans

The testes secrete anti-Müllerian hormone around this time to suppress the development of the Müllerian ducts, and cause their degeneration.

Without this anti-Müllerian hormone, the Müllerian ducts develop into the female internal genitalia ( uterus, cervix, fallopian tubes, and upper vaginal barrel ).

This action of androgens is supported by a hormone from Sertoli cells, MIH ( Müllerian inhibitory hormone ), which prevents the embryonic Müllerian ducts from developing into fallopian tubes and other female reproductive tract tissues in male embryos.

* Anti-Müllerian hormone, a protein that inhibits the development of Müllerian ducts during sexual development of human male embryos

The development of the Müllerian ducts is controlled by the presence or absence of " AMH ", or Anti-Müllerian hormone ( also known as " MIF " for " Müllerian-inhibiting factor ", or " MIH " for " Müllerian-inhibiting hormone ").

The Heliconius butterflies from the tropics of the Western Hemisphere are the classical model for Müllerian mimicry.

Other genetic conditions can result in the loss of the Wolffian ducts and allow for the persistence of Müllerian ducts.

Bates, Wallace and Müller believed that Batesian and Müllerian mimicry provided evidence for the action of natural selection, a view which is now standard amongst biologists.

Although it was for a long time purported to be an example of Batesian mimicry, it has recently been discovered that the viceroy is actually more unpalatable than the monarch, making this a case of Müllerian mimicry.

During this surgery, the uterus is usually removed and attempts made to dissect away Müllerian tissue from the vas deferens and epididymis for the purpose of improving the chance of fertility.

In Müllerian mimicry an advantage is gained when unpalatable species resemble each other, especially when the predator has a good memory for colour ( as birds, for instance, do have ).

* What someone could easily mistake for a butterfly, a wasp, or a leaf in Costa Rica might be a moth engaging in Müllerian or Batesian mimicry.

Although it was for a long time purported to be an example of Batesian mimicry, the viceroy has recently been discovered to be actually just as unpalatable as the monarch, making this a case of Müllerian mimicry.

The paired Müllerian glands inside the male cloaca secrete a fluid which resembles that produced by mammalian prostate glands and which may transport and nourish the sperm.

The arrangement of the spines is very precise, and is described by what is called the Müllerian law.

Until approximately the seventh week of development, the embryo has indifferent sex accessory ducts, which consist of two pairs of ducts: the Müllerian ducts and the Wolffian ducts.

Unlike the Müllerian ducts, the Wolffian ducts will not continue to develop by default.

Clinical findings indicative of AIS include the presence of a short vagina or undermasculinized genitalia, partial or complete regression of Müllerian structures, bilateral nondysplastic testes, and impaired spermatogenesis and / or virilization.

These butterflies are Müllerian mimics whose coloration pattern arose in different evolutionary events, but is controlled by the same genes.

Considering that the Lesser Kestrel would in fact have an advantage if some would-be predators confuse it with the larger species and consequently avoid it, it might be a case of Müllerian mimicry.

:* Malignant mixed Müllerian tumors are rare endometrial tumors which show both glandular ( carcinomatous ) and stromal ( sarcomatous ) differentiation – carcinosarcoma behaves similar to a high grade carcinoma, and it is felt to be of epithelial origin rather than true sarcoma.

The birds ' bright colours are suggested to be an example of aposematism ( warning colouration ), and the similarity of the Hooded Pitohui and some forms of the Variable Pitohui might then be an example of Müllerian mimicry, in which dangerous species gain a mutual advantage by sharing colouration, so an encounter with either species trains a predator to avoid both.

Many social wasp ( Vespidae ) species exhibit Müllerian mimicry, where a group of unpalatable species benefit from sharing the same kind of warning ( aposematic ) colouration.

Warning coloration, if it involves more than one species, is known as Müllerian mimicry, a form of convergent evolution where multiple species share the same advantageous pattern.

In this case, testosterone is not made and the Wolffian duct will degrade thus, the Müllerian duct will develop into female sex organs.

High prolactin levels also tend to suppress the ovulatory cycle by inhibiting the secretion of both follicle-stimulating hormone ( FSH ) and gonadotropin-releasing hormone ( GnRH ).

Leptin works by inhibiting the activity of neurons that contain neuropeptide Y ( NPY ) and agouti-related peptide ( AgRP ), and by increasing the activity of neurons expressing α-melanocyte-stimulating hormone ( α-MSH ).

Melatonin can suppress libido by inhibiting secretion of luteinizing hormone ( LH ) and follicle-stimulating hormone ( FSH ) from the anterior pituitary gland, especially in mammals that have a breeding season when daylight hours are long.

Hyperprolactinaemia inhibits gonadotropin-releasing hormone ( GnRH ) by increasing the release of dopamine from the arcuate nucleus of the hypothalamus ( dopamine inhibits GnRH secretion ), thus inhibiting gonadal steroidogenesis, which is the cause of many of the symptoms described below.

These children possibly have a problem with growth hormone inhibiting hormone ( GHIH ) or growth hormone releasing hormone ( GHRH ).

The axons of the parvocellular neurosecretory neurons of the PVN project to the median eminence, at the base of the brain, where their neurosecretory nerve terminals release peptides vasopressin, corticotropin-releasing hormone ( CRH ), thyrotropin-releasing hormone ( TRH ), gonadotropin-releasing hormone ( GnRH ), growth hormone-releasing hormone ( GHRH ), and somatostatin ( growth hormone release inhibiting hormone, GIH ) into blood vessels in the hypothalamo-pituitary portal system.

Secretion is regulated by growth hormone releasing hormone ( GHRH ) and growth hormone inhibiting hormone ( GHIH ), or somatostatin.

Appearance of new glucose is slowed down by inhibiting secretion of the gluconeogenic hormone glucagon.

Wilting is an effect of the plant growth inhibiting hormone, Abscisic acid.

The last involves rhythmic release of Neuropeptide Y ( NPY ) and Corticotropin-releasing hormone ( CRH ), stimulating and inhibiting appetite ultradian rhythms.
