It was originally attributed to mumps, but after further studies by Swedish doctor Jan G. Waldenström in 1937, it was classified as a distinct manifestation of sarcoidosis. See also

An example of this effect is that the male:female ratio of children born prior and subsequent to secondary recurrent miscarriage is 1.49 and 0.76 respectively. Ovarian factors
Luteal phase defect
The issue of a luteal phase defect is complex. The theory behind the concept suggests that an inadequate amount of progesterone is produced by the corpus luteum to maintain the early pregnancy. Assessment of this situation was traditionally carried out by an endometrial biopsy, however recent studies have not confirmed that such assessment is valid. Studies about the value of progesterone supplementation remain deficient, however, such supplementation is commonly carried out on an empirical basis. Infection
Infections are estimated to be responsible for between 0.5 and 5% of cases with recurrent miscarriage. The main suspected pathogens are mycoplasma, ureaplasma, Chlamydia trachomatis, Listeria monocytogenes, and herpes simplex virus. An infectious evaluation may be warranted in people with immunodeficiency, or with signs of chronic endometritis/cervicitis on examination. Otherwise, there is no evidence that routine infectious evaluation is appropriate or productive.Chronic endometritis (CE) due to common bacteria has been found to be prevalent in some women with a history of recurrent miscarriage. One study found that 71 percent of women who tested positive for this condition were successfully treated by an antibiogram-based antibiotic treatment. 78.4 percent of these women subsequently became pregnant in the year following treatment. The study concludes that "CE is frequent in women with recurrent miscarriages," and that "antibiotic treatment seems to be associated with an improved reproductive outcome."
