Overview

[edit]

Follicular atresia refers to the process in which a follicle fails to develop, thus preventing it from ovulating and releasing an egg.[3] It is a normal, naturally occurring, progressive process that encompasses the breakdown of the ovarian follicles which are made in mammalian ovaries in order to secrete hormones and oocytes. Oocytes are immature eggs and are surrounded by granulosa cells and internal and external theca cells.[4] Oocytes are then able to mature within the follicle through meiosis. However, in female humans, this process occurs continuously, as they are born with a finite number of follicles (between 500,000-1,000,000 follicles), and about 99% of follicles undergo atresia[5]. Only one follicle will be mature enough to release an egg and may be fertilized[6]. Typically, around 20 follicles mature each month, but only a single follicle is ovulated; the follicle from the oocyte was released becomes the corpus luteum. The corpus luteum is the last stage of the ovarian follicles' lifecycle. It has an important role in secreting estrogen and progesterone to prepare the body for conception. If conception does not occur, then it will be shed and is known as the corpus albicans[7]. It has been observed that this mechanism is important in regulating and maintaining a healthy reproductive system in mammals. It is also a subject of interest in understanding and predicting fertility in female humans. Approximately 1% of mammalian follicles in ovaries undergo ovulation and the remaining follicles go through follicular atresia as it cycles through the growth phases. In summary, follicular atresia is a process that leads to the follicular loss and loss of oocytes, and any disturbance or loss of functionality of this process can lead to many other conditions.

Layers of a mature, ovarian follicle.

Mechanism

[edit]

Atresia is a complex, hormonally controlled apoptotic process that depends dominantly on granulosa cell apoptosis, however there have been other proposed mechanisms in which this pathway occurs. In the most known mechanism, apoptosis, follicular atresia is inhibited by follicle-stimulating hormone (FSH), which promotes follicle development. Once the follicle has developed, it secretes estrogen, which in high levels decreases secretions of FSH. Granulosa cell apoptosis is considered the underlying mechanism of follicular atresia, and has been associated with five ligand-receptor systems involved in cell death: [4][8]

Granulosa cell apoptosis is induced by tumor necrosis factor-alpha (TNFα), although the mechanism of how it occurs is unclear.[9]

Fas antigen, a cell surface receptor protein, is expressed on granulosa cells and helps mediate signals that induce apoptosis by binding Fas ligand and therefore plays an important role in follicular atresia.[10] Lack of a working Fas ligand / Fas receptor system has been linked to abnormal follicle development, and increased secondary follicles as a result of the inability to induce apoptosis.[11]

TNF-related apoptosis-inducing ligand (TRAIL) activates caspase 3 (CASP3), which interacts with caspases 6, 7, 8, 9, and 10, to induce apoptosis in granulosa cells.[12]

In addition, two intracellular inhibitor proteins, cellular FLICE-like inhibitory protein short form (cFLIPS) and long form (cFLIPL), which are strongly expressed in granulosa cells, may act as anti-apoptotic factors.[13]

Anti-Mullerian hormone (AMH) has been studied to be a key regulator in the ovaries in humans that inhibits follicular atresia. Using indirect comparators to derive this hypothesis, exploring different patient populations such as individuals who have polycystic ovary syndrome (PCOS) help support the hypothesis that AMH may be a key regulator in inhibiting follicular atresia. [14]

Menopause

[edit]

Follicular atresia occurs throughout all stages of follicular development, until the follicular reserve is completely exhausted.[15] Exhaustion of the follicular reserve occurs at menopause, which is typically around the age of 51 in humans with ovaries. The dramatic decrease in estrogen and progesterone levels that is characteristic of menopause, is caused by follicular atresia. Breakdown of the follicles prevent them from releasing hormones such as estrogen. Progesterone levels also decrease during menopause because without any follicles, there is no development of a corpus luteum, which is the major source of circulating progesterone levels in humans.[16]

Studies have shown that follicular atresia does not occur at a constant rate.[15]

[edit]

Undergoing follicular atresia is necessary in order for mammals to maintain a healthy reproductive system. Mammalian ovaries ovulate about 1% of the follicles and the remaining follicles may go through atresia as it cycles through the growth phases.[17] However, disorders in the regulation of follicle breakdown and generation can lead to various pathologies:

Premature Ovarian Failure[18]

[edit]

Premature ovarian failure (POF) (also called premature ovarian insufficiency) is the loss of ovarian function before the age of 40 due to follicular dysfunction such as accelerated follicular atresia. POF may present itself with characteristics and symptoms such as loss of menstruation for at least 4 months and also increased serum follicle-stimulating hormone (FSH) concentration (greater than or equal to 40 IU/L).[19] There may be many causes of POF, ranging from genetic disorders to surgery, radiation therapy, and exposure to environmental toxicants. Accelerated follicular atresia due to chromosomal and genomic defects accounts for up to one-half of all POF cases. For example, Fragile X syndrome, Turner syndrome, and various autosomal diseases such as galactosemia have been linked to follicular deficiencies. Smoking has also been found to increase follicular atresia and lead to premature ovarian failure.[20] Some of the short term effects of POF are hot flashes, irregular heart beat/ heart palpitations, night sweats, urogenital symptoms, and headaches; some of the more long terms consequences of POF are osteoporosis, infertility, cardiovascular diseases, and possible premature death.[21]

Ovarian Follicular Cysts[22][23]

[edit]

When an ovarian follicle fails to undergo atresia and release an egg, it can grow to form a cyst. This may be due to an overproduction of FSH or an inadequate supply of LH. Most follicular cysts are harmless and resolve on their own within several months. However, rarely a cyst will grow to be very large (greater than 7 cm), cause abdominal pain or rupture, or last for longer than a few months, in which case a physician may recommend surgical removal or testing to determine if it is cancerous. Ultrasound is a common method of visualizing a cyst to determine treatment.

Ovarian Cancer

[edit]

Ovarian cancer is highly prevalent amongst humans who have ovaries and leads to many deaths in the United States.[24] Since FSH inhibits follicular atresia, the overproduction of FSH can lead to excessive follicle formation and increased risk of ovarian cancer. [25]

The inability to regulate granulosa cell apoptosis has been linked to the development of some hormone-related cancers and chemo-resistance.[+orig. citation here]

According to the gonadotropin theory, follicular depletion associated with incessant follicular atresia has also been hypothesized as a potential etiology for ovarian cancer, due to an increase in serum gonadotropins. This leads to an inflammatory environment which promotes cellular turnover and tumor development.[26]

Ovarian cancer is characterized by some generalized symptoms such as bloating or swelling in the abdomen, pelvic pain, gastrointestinal symptoms (i.e. loss of appetite, nausea, constipation, and unexpected weight loss).[27] Many people who are diagnosed with ovarian cancer also report feeling very full fast and many of them having a feeling on unexpected continuous bloating in their abdomen.[28]

Polycystic Ovary Syndrome (PCOS)[29]

[edit]

Polycystic Ovary Syndrome, or PCOS affects 6-12% of human females of reproductive age in the United States and is one of the common reasons of female infertility. Diagnosis of PCOS is based on at least two of the three following clinical criteria according to the Rotterdam Criteria: chronic anovulation, hyperandrogenism, and polycystic ovaries. The mechanism of PCOS is still unknown, but it has been observed that those with PCOS have higher levels of androgens and large number of ovarian cysts. [30]

Morphology

[edit]

From studying dairy cows, two forms of follicular atresia have been identified: antral and basal.

Antral

Antral follicular atresia is characterized by the apoptosis of granulosa cells within the antral layers of the granulosa membrane and sometimes within the antrum itself. During this process, the presence of pyknotic nuclei in the antral layers of the membrane can be observed.[31] Apoptosis ensures that the follicle gets eliminated without triggering an inflammatory response.[32] Antral follicular atresia causes no damage to basal granulosa cells. This type of follicular atresia is often considered the classic and most commonly observed form. In most species, it occurs throughout follicular development and is universally seen in large follicles (>5 mm diameter).[32]

Basal

Basal follicular atresia is characterized by the destruction of granulosa cells in the basal layer of the granulosa membrane. Macrophages have often been observed, penetrating the basal lamina during this type of follicular atresia. These macrophages phagocytose the basal granulosa cells. An increased deposition of collagen in the theca layer of the follicle can also be observed.[31] Basal follicular atresia causes no damage to antral granulosa cells.This form of follicular atresia has only been observed in small follicles of dairy cows (< 5mm diameter), and has not been reported in any other species.[32]
