Shift workers and flight attendants, whose own body clocks are disrupted, also report increased miscarriages and menstrual changes.
It is possible that manipulation of RFRP3 signaling in humans may relieve stress-related reproductive dysfunction, including decreased sex drive, impaired fertility, and increased miscarriages.
Indeed, untreated depression during pregnancy is associated with increased miscarriage rates, preterm birth, and low birth weight some of the very risks associated with maternal use of S.S.R.I.s.

Endometrial polyps may be associated with increased miscarriage rates.
An increased miscarriage rate has been observed in women with polycystic ovarian disease, a disorder which is characterized by amenorrhoea, hirsutism, and raised androgen concentrations [1],[3].
Except for the thalassemia trait, this patient has no family history of genetic predisposition for cancer or an increased miscarriage frequency.
Our study was designed to have 80% power to detect a minimum odds ratio of 2 for increased miscarriage risk in the exposed group with an alpha = 0.05.
Our analyses, which do not indicate an increased miscarriage risk either overall or for pregnancies conceived less than 90 days after vaccination, provide additional support to these recommendations.
The effects of Chlamydia trachomatis, Toxoplasma gondii, human papillomavirus, herpes simplex virus, parvovirus B19, Hepatitis B and polyomavirus BK infections remain controversial, as some studies indicate increased miscarriage risk and others show no increased risk.
These data do not indicate a strong association between chlorination by-products and adverse pregnancy outcome, but given the limited quality of our exposure assessment and the increased miscarriage risk in the highest exposure group, more refined evaluation is warranted.
