British researchers said that the rate of spontaneous miscarriage following a male pregnancy is greater than that which occurs when a female pregnancy occurs. According to researchers at the University of Exeter, under the supervision of Fiona Matthews, in a statement, the rate of male falls resulting from pregnancy at an advanced stage is about 10% higher than the rate of female falls, which equates to about 100,000 additional falls worldwide annually.
According to researchers, the rate of spontaneous abortion in males reached 6.23 out of every 1,000 births, compared to 5.74 in females out of every 1,000 births. The rate of spontaneous abortion in rich countries was clearly lower than in poor countries, as the number of failed pregnancies in Finland amounted to only two cases for every 1,000 advanced pregnancies, while the number of spontaneous abortions at a late stage of pregnancy reached more than 40 cases in both Nigeria and Pakistan. While the rate of spontaneous abortion remains higher in the case of male pregnancies compared to female pregnancies.
The study included an analysis of more than 30 million births worldwide. The definition of a failed pregnancy varied depending on the country from which the data were taken. The researchers limited the definitions of a failed birth at a late stage to two definitions: that the birth weighs at least 400 to 500 grams, or that the birth occurs between the twentieth and twenty-eighth weeks, that is, before the thirty-seventh week, which is the usual pregnancy period. It was previously known that male pregnancies are more complicated. Of female pregnancies, as the rate of premature birth when the fetus is male is greater than the rate of premature birth when the baby is female. +++++++ My comment on the topic: Yes, this report is correct, but it did not mention the reasons that make pregnancy with males difficult = I have preceded this study, as I had indicated on my page ** Determining the sex of the fetus how ** Pregnancy with a female is easy and requires intercourse Every night during the fertile days. As for pregnancy with a boy, it requires skipping the day of the egg’s release, and as is known, determining the day of the egg’s release is difficult. Moreover, getting pregnant with a boy requires waiting for the male sperm for about 3 days to fertilize the egg, as its remaining in the uterus is exposed to harm. Therefore, we find that pregnancy with a boy sometimes fails.
