The luteal phase of the menstrual cycle begins after ovulation and goes through the start of menstruation. As mentioned above, during the luteal phase, the hormone progesterone plays an important role in triggering the endometrium to secret essential nutrients and substances. These both sustain the endometrium and create a healthy environment for an embryo.
A luteal phase defect is a potential cause of infertility. It occurs when progesterone levels are not high enough or not sustained long enough to keep the endometrium intact and prepared for the implantation of an embryo. At one time, luteal phase defects LPD were diagnosed via an endometrial biopsy. This is still sometimes done. More commonly, luteal phase defects can be diagnosed via blood work testing progesterone levels.

If the levels are not high enough or are not sustained long enough, this may indicate a luteal phase deficiency. Other possible signs of a luteal phase defect are Women who chart their basal body temperature may recognize this abnormal pattern before they realize they have a fertility problem.
This is one of many advantages of charting. Endometriosis is a condition in which endometrium is found outside the uterine cavity.

It is a common cause of infertility. While endometriosis is primarily defined by endometrial tissue growing in the wrong places, it can also affect the uterine environment, the endometrium itself, and ovulation. Endometrial or Uterine Polyps.
An endometrial polyp is an overgrowth of the endometrium. They are usually non-cancerous and benign, but not always.
mately 8, endometrial biopsies have been examined in this laboratory. It is the purpose of this paper briefly to review these criteria, analyze their accuracy, and evaluate the usefulness of dating the endometrial biopsy. Not all variations that occur in the endometrium are useful for dating. For. That's an endometrial cyst. Some women with endometriosis also have an endometrial cyst. You could have only one, or you could have a cyst on each of your ovaries. While they're often small. The stratum basalis, also known as the basal layer. This is the deepest endometrial layer that sits against the myometrium of the uterus. It does not change much throughout the cycle. Think of it as the base from which the changing layers of the endometrium grows. The stratum spongiosum: this is a spongy intermediate layer of the endometrium.
The presence of an endometrial poly may cause infertility, but not necessarily. This may enable you to conceive without additional fertility treatments. Adenomyosis is when the endometrium grows into the myometrium the muscular layer of the uterus. It can cause painful, heavy periods.
The primary treatments for adenomyosis have been endoscopic endometrial ablation which involves the destruction of the endometrium or hysterectomy which is the removal of the uterus. Neither of these treatments is appropriate if you still want to have children. For women still wanting to have kids, there are other options:.
This is scar tissue that grows in sheets inside the uterus. Sometimes, its cause is unknown. It can be treated during a hysteroscopy, a procedure that both allows for both the diagnosis and removal of the scar tissue.
For endometrial dating, the phase assignment is made based on previous histological dating by at least two independent pathologists. Figure 1 Principal component analysis of human endometrium throughout the development of the luteal phase in natural (LH + n) and controlled ovarian stimulation cycles (human chorionic gonadotropin + n). The endometrium consists of a single layer of columnar epithelium plus the stroma on which it rests. The stroma is a layer of connective tissue that varies in thickness according to hormonal influences. In the uterus, simple tubular glands reach from the endometrial surface through to the base of the stroma, which also carries a rich blood supply provided by the spiral arteriesMeSH: D Endometrial definition, the mucous membrane lining the uterus.

A viral infection found in the endometrium may cause infertility and recurrent pregnancy loss. A small but possibly groundbreaking study has found a possible connection between the herpes virus HHV-6A and infertility. When most people think of herpes, they think of the sexually transmitted disease herpes simplex virus 2, or HSV However, herpes simplex is just one possible form of the virus.
The herpes family of viruses is also responsible for chicken pox, mononucleosis, and the common cold sore. HHV-6 is suspected of being passed along via saliva and is most known for causing a common viral childhood rash, roseola, in children.

Like the other herpes viruses, even after the initial infection passes, the virus remains dormant in the body. Researchers suspect HHV-6 may be associated with other health issues, beyond childhood rashes.
A study in Italy of 30 infertile women and 36 controls who had already given birth to at least one child looked into whether HHV-6A might be correlated with infertility. All the women in the study had endometrial biopsies. Researchers discovered that of the infertile women, 43 percent had genetic evidence of the HHV-6A virus in their endometrial samples.
Some possibilities that future research may investigate include anti-viral medications or immunological treatments meant to calm down the body's natural immune response to the virus, which may be interfering with embryo implantation or attacking the embryo before it can develop into a baby.
