Presently such a program does not exist in the community, but a community of practice has formed to address this deficiency. Women with POI perceive lower social support than control women, so building a trusted community of practice for them would be expected to improve their well-being. Also, when having that social support, it often helps with reducing stress and having better coping skills. It is important to connect women with POI to an appropriate collaborative care team because the condition has been clearly associated with suicide related to the stigma of infertility. Suicide rates are known to be increased in women who experience infertility. Epidemiology
The prevalence increases with age and is approximately 1 in 10,000 women under age 20, 1 in 1,000 women under age 30, and one percent by age of 40. History
Fuller Albright et al. in 1942 reported a syndrome with amenorrhea, estrogen deficiency, menopausal FSH levels, and short stature. They used the term "primary ovarian insufficiency" to distinguished POI from ovarian insufficiency secondary to a primary failure of pituitary FSH and other hormonal secretion. POI has been described as a more accurate and less stigmatizing term than premature ovarian failure or premature menopause.Chapter 28 of the early Qing dynasty work Fù Qīngzhǔ Nǚkē (《傅青主女科》Fù Qīngzhǔs Gynecology) describes the cause and appropriate treatment for premature menopause. 年未老经水断 (niánwèilǎo jīngshuǐduàn) glosses as not yet old, menstrual water cut-off.

This bleeding often starts mildly and may increase as the area of placental separation increases. Placenta praevia should be suspected if there is bleeding after 24 weeks of gestation. Bleeding after delivery occurs in about 22% of those affected.Women may also present as a case of failure of engagement of fetal head. Cause
The exact cause of placenta previa is unknown. It is hypothesized to be related to abnormal vascularisation of the endometrium caused by scarring or atrophy from previous trauma, surgery, or infection. These factors may reduce differential growth of lower segment, resulting in less upward shift in placental position as pregnancy advances. Risk factors
The following have been identified as risk factors for placenta previa:

Previous placenta previa (recurrence rate 4–8%), caesarean delivery, myomectomy or endometrium damage caused by D&C. Women who are younger than 20 are at higher risk and women older than 35 are at increasing risk as they get older. Women who have had previous pregnancies (multiparity), especially a large number of closely spaced pregnancies, are at higher risk due to uterine damage. Smoking during pregnancy; cocaine use during pregnancy
Women with a large placentae from twins or erythroblastosis are at higher risk. Race is a controversial risk factor, with some studies finding that people from Asia and Africa are at higher risk and others finding no difference. Placental pathology (velamentous insertion, succenturiate lobes, bipartite i.e. bilobed placenta etc.) Baby is in an unusual position: breech (buttocks first) or transverse (lying horizontally across the womb).Placenta previa is itself a risk factor of placenta accreta.
