@pherdal_science: Replying to @funkyfresh - this is false. The cause for 50% of all #miscarriage ‘s is chromosomal abnormalities from either the man or the woman and is dependent aupon which sperm and which egg meet. Each partner has 46 chromosomes and has to create gametes (fancy name for egg and sperm) with 23 chromosomes each. If during this process the chromosomes dont split equally - it can cause a miscarriage. Heres a paper from 2021 explaining more: Miscarriage matters: the epidemiological, physical, psychological, and economic costs of early pregnancy loss Siobhan Quenby, et al. The Lancet 397 (10285), 1658-1667, 2021 Miscarriage is generally defined as the loss of a pregnancy before viability. An estimated 23 million miscarriages occur every year worldwide, translating to 44 pregnancy losses each minute. The pooled risk of miscarriage is 15·3% (95% CI 12·5–18·7%) of all recognised pregnancies. The population prevalence of women who have had one miscarriage is 10·8% (10·3–11·4%), two miscarriages is 1·9% (1·8–2·1%), and three or more miscarriages is 0·7% (0·5–0·8%). Risk factors for miscarriage include very young or older female age (younger than 20 years and older than 35 years), older male age (older than 40 years), very low or very high body-mass index, Black ethnicity, previous miscarriages, smoking, alcohol, stress, working night shifts, air pollution, and exposure to pesticides. The consequences of miscarriage are both physical, such as bleeding or infection, and psychological. Psychological consequences include increases in the risk of anxiety, depression, post-traumatic stress disorder, and suicide. Miscarriage, and especially recurrent miscarriage, is also a sentinel risk marker for obstetric complications, including preterm birth, fetal growth restriction, placental abruption, and stillbirth in future pregnancies, and a predictor of longer-term health problems, such as cardiovascular disease and venous thromboembolism. #ttc #miscarriage #infertility #ttcjourney #science #phd #ttcjourney #infertilitystruggles #Inverted
