While there may be little that science can do to change the number of eggs that nature or genetics decides a woman will have during her life, Wells and Jurisicova agree there are ways to improve, or rescue, egg quality. Adopting a healthy lifestyle, exercising regularly, reducing stress and making sure that health problems such as hypothyroidism and other autoimmune conditions are well controlled can all help. The range of factors pitched against an egg being fertilised and developing into a foetus make childbirth seem all the more incredible Credit: Science Photo Library.
Jurisicova recently found that giving female mice the antioxidant coenzyme Q10 delivers promising results — the mice that received the supplement produced better quality eggs with more properly aligned chromosomes and better mitochondrial function.
They were also more successful in producing live babies , than the mice that did not receive the supplements. The results are, however, yet to be replicated in humans. They found mothers over 40 were two to three times more likely to experience health problems during pregnancy including diabetes and high blood pressure.
They were twice as likely to experience bleeding from their placentas, have a caesarean delivery and to lose their baby later on in pregnancy. The children of older first-time mothers who are 40 years and above also have an increased risk of health problems at birth, such as low birth weight and congenital abnormalities. But this is still only one half of the equation. Older fathers also bring additional health risks for their children.
Babies with older fathers are more likely to be born prematurely, have a lower birth weight and higher risk of seizures. Some studies have also linked increasing paternal age to a greater risk of conditions such as autism and ADHD where the father is over the age of 40, but the evidence remains inconsistent. Is it possible to extend female fertility and for how long? As is often the case, where nature creates inequity, science attempts to level the playing field. Three years ago, year-old Daljinder Kaur, from north India, gave birth to a son after nearly five decades of marriage and two unsuccessful IVF attempts.
The significant advances in reproductive medicine over the past decades have greatly increased the safety, success, accessibility and affordability of artificial reproductive techniques. But as we have seen, these techniques are still limited to a degree by the age of the egg.
This is, not least, because of the effects of ageing on the DNA, but also because older eggs have been exposed to environmental toxins for a longer amount of time. So, couples with the following signs or symptoms should not delay seeing their health care provider when they are trying to become pregnant: Irregular periods or no menstrual periods.

This medicine is taken by mouth. It is often used to induce ovulation in woman with PCOS, and in women with normal ovulation to increase the number of mature eggs produced in the ovaries. It is taken by mouth. It stimulates development of mature eggs within the ovaries. Gonadotropin-releasing hormone GnRH analogs and GnRH antagonists are medications that act on the pituitary gland to prevent a woman from ovulating. These medications are usually injected or given with a nasal spray.
This drug helps lower the high levels of male hormones in women with these conditions. This helps the body to ovulate. Sometimes clomiphene citrate or FSH is combined with metformin.
These medications are taken by mouth. What is intrauterine insemination IUI? IUI is often used to treat: Mild male factor infertility. Couples with unexplained infertility. What is assisted reproductive technology ART?
How often is assisted reproductive technology ART successful? What are the different types of assisted reproductive technology ART? Eggs and sperm are combined in a laboratory to create embryos.
Embryos can also be frozen for a future transfer. With ICSI, a single sperm is injected into a mature egg. Then the very young embryo is transferred to the fallopian tube instead of the uterus. What is preimplantation genetic testing PGT?

After birth, the surrogate will give up the baby for adoption by the parents. Women with ovaries but no uterus may be able to use a gestational carrier. This may also be an option for women who shouldn't become pregnant because of a serious health problem.
In this case, a woman uses her own egg. It is fertilized by the man's sperm and the embryo is placed inside the carrier's uterus. The carrier will not be related to the baby and gives him or her to the parents at birth. Recent research by the Centers for Disease Control and Prevention showed that ART babies are two to four times more likely to have certain kinds of birth defects. These may include heart and digestive system problems, and cleft divided into two pieces lips or palate.
Researchers don't know why this happens. The birth defects may not be due to the technology. Other factors, like the age of the parents, may be involved. More research is needed. The risk is relatively low, but parents should consider this when making the decision to use ART.
