Despite the greater likelihood that having such a stupid mother, any child will be poorly raised and grow up disadvantaged. So, nope. I disagree. With god being the greatest abortionist of all: 20% of all pregnancies end in miscarriage---something god could surely prevent---his message is: fetuses just aren't all that important.
.
Poor comparison. Most all miscarriage are due to a problem or injury within the system. Abortion is per choice.
A god isn't involved in either.
Main causes of a miscarriage-
1. Genetic or chromosomal abnormalities:
For about half of miscarriages that happen sporadically, it’s usually due to a chromosomal abnormality such as Down syndrome, cystic fibrosis or Turner syndrome.
2. Sperm DNA fragmentation:
Another cause for miscarriage that is often overlooked, but is believed to be very common, is a factor known as sperm DNA fragmentation. This occurs when strands of sperm DNA are broken and unable to deliver DNA to the egg. Although there are different levels of severity, the likelihood of miscarriage is 2 to 5 times higher for men that have the condition, compared to men that have healthy sperm, said Dr. Philip Werthman, a urologist and director of the Center for Male Reproductive Medicine and Vasectomy Reversal in Los Angeles, California.
3. Hormones:
Luteal phase defect, or low progesterone levels in the second half of the cycle, can cause problems with implantation. Women with the condition will have spotting in the second half of their cycle before their period. Hypothyroidism and diabetes are two other hormonal problems that can lead to miscarriage.
4. Obesity:
According to the a report by the CDC National Center for Health Statistics, nearly 1 in 4 women are obese before becoming pregnant, which is an independent risk factor for miscarriage, Hirshfeld-Cytron said.
5. Balanced translocation carrier:
Approximately 2 to 5 percent of miscarriages are a result of what’s known as a balanced translocation carrier, which happens when one or both partners has genes that are misplaced. The problem doesn’t manifest itself until the cells divide and try to make sperm or egg cells, which can then cause the pregnancy to end in miscarriage, Gross said. A simple blood test can determine if you or your partner are carriers. A procedure known as preimplantation genetic diagnosis can help to ensure the embryo is healthy.
6. Abnormalities of the uterus
Another common reason for miscarriage are genetic abnormalities of the uterus. One type, a septum, is the most widely experienced and also the easiest to treat. A septum is an extra piece of tissue on the uterus that doesn’t have the same type of blood supply as the rest of the uterus.
7. Antiphospholipid syndrome:
Thrombophilias are a group of disorders that increase the likelihood of clotting. Those that are inherited have not been shown to cause miscarriage but those that are acquired can. Antiphospholipid Syndrome, the most common type, causes an elevation in the antiphospholipid antibodies that can cause the blood to clot and interfere with the implantation and growth of the developing embryo, Hirshfeld-Cytron said.
8. Drugs and toxins:
Smoking, alcohol and drug use can all increase your risk for miscarriage. Additionally, women exposed to high levels of toxic chemicals like bisphenol A (BPA) found in plastics are 83 percent more likely to have a miscarriage than women with lower levels, according to a study in the journal Fertility and Sterility.
9. Infections:
Mycoplasma infections that happen in the lining of the uterus have no symptoms but can lead to miscarriage. Causes can include variations of the body’s normal flora and increases or decreases in acidity that cause bacterial overgrowth. Women who have had multiple gynecologic procedures are more at risk.
