Miscarriage stories of loss, hope and help. It's always devastating to experience a loss. It can cause you to feel alone, isolated. There's no 'right' way to feel - a range of reactions are possible and normal. In addition to the grief you may feel, your body will be undergoing some profound hormonal adjustments, which may make you feel very emotionally volatile. If you have had a miscarriage, take the time to understand better why these occur and why it is not your fault.

Health effects of egg donation may take decades to emerge
Nature Published online: 9 August 2006
A Nature Special Report investigates the ethics and economics of donating eggs for stem-cell research. In the first part Erika Check investigated whether paying donors would increase supply. In this, the second part Helen Pearson asks what is known about the long-term health risks faced by donors.
In 1989, a healthy 32-year-old woman offered her infertile younger sister some of her healthy eggs, and with them the chance to have a baby. Doctors at the Cromwell IVF and Fertility Centre in London gave the donor hormones that made a batch of eggs in her ovary mature, and collected six eggs for fertilization. Three embryos were transferred to the younger sister and two were frozen. One baby girl was born. Five years later, the doctors contacted the egg donor to ask whether to discard her frozen embryos. They discovered that she had been diagnosed with late-stage colon cancer that spread to her skull. She died just before her thirty-ninth birthday. Doctors don't know if the fertility drugs caused or accelerated the woman's cancer. But the possibility prompted Cromwell infertility specialist Kamal Ahuja to report the case as a reminder of how little is known about the risks of donating eggs (K. E. Ahuja and E. G. Simons, Hum. Reprod. 13, 227–231; 1998). "It shook us all up," he says.

Marijuana Use Causes Early Pregnancy Failure
Marijuana use at the time of conception and early in pregnancy prevents embryos' safe passage from the ovary to the uterus, resulting in early pregnancy failure, suggests a new study in mice. The study appears in the August issue of the Journal of Clinical Investigation.

Older Men Linked to Miscarriages
A new study from Columbia University has demonstrated a link between miscarriage and paternal age. Examining 14,000 women from Jerusalem who were pregnant during the 1960s and 1970s, investigators found a 60% increase in miscarriage risk when the father of the child was over age 40 compared to men aged between 25 and 29 years old. Men between the ages of 35 and 39 increased their partner’s risk of miscarriage by threefold compared to men under 25. This study backs up previous research that has found a decline in men’s fertility as they age.
