The female reproductive system is composed of two embryological segments: the urogenital sinus and the paramesonephric ducts. The two are conjoined at the sinus tubercle. [2] [3] Paramesonephric ducts are present on the embryo of both sexes.
The normal follicular function, oocyte population and estrogen levels in women with Müllerian anomalies occurs as normal ovarian function is not compromised in the disease. In patients with uterine anomalies, there may be a chance that the endometrial cavity can be compromised, such that implantation following IVF does not always lead to a ...
Sinus tubercle (also known as sinual tubercle [1] or Müllerian eminence) is the proliferation of endoderm induced by the paramesonephric ducts.It is located in the developing fetus between the orifices of the mesonephric ducts on the urogenital sinus. [1]
The only known effect is that the Wallerian degeneration is delayed by up to three weeks on average after injury of a nerve. At first, it was suspected that the Wld s mutation slows down the macrophage infiltration, but recent studies suggest that the mutation protects axons rather than slowing down the macrophages. [ 7 ]
Basic cellular compartments. Cellular compartments in cell biology comprise all of the closed parts within the cytosol of a eukaryotic cell, usually surrounded by a single or double lipid layer membrane. These compartments are often, but not always, defined as membrane-bound organelles. The formation of cellular compartments is called ...
Because its main function is to nourish developing sperm cells through the stages of spermatogenesis, the Sertoli cell has also been called the "mother" or "nurse" cell. [10] Sertoli cells also act as phagocytes, consuming the residual cytoplasm during spermatogenesis. Translocation of cells from the basal lamina to the lumen of the ...
The effect is ipsilateral, that is each testis suppresses Müllerian development only on its own side. [21] If no hormone is produced from the gonads, the Müllerian will develop thanks to the presence of Wnt4 , while the Wolffian ducts , which are responsible for male reproductive parts, will die due to the presence of COUP-TFII.

Persistent Müllerian duct syndrome (PMDS) is the presence of Müllerian duct derivatives (fallopian tubes, uterus, and/or the upper part of the vagina) [1] in what would be considered a genetically and otherwise physically normal male. [2]
