Miscarriage Causes: Hormonal 20%
- Polycystic ovary syndrome – this disease can cause infertility and frequently affects success of even conceiving. This syndrome together with a raised hormone level luteinising hormone (LH) results in an increased risk of miscarriage.
- Hormone ‘deficiency’ – in pregnancies ending in miscarriage, sometimes the levels of a hormone called progesterone are found to be low. This is thought to be the result rather than the cause of the miscarriage. Progesterone supplements do not appear to increase the likelihood of an ongoing pregnancy.
