Transferring One Embryo or More – Weighing the Risks

June 19, 2017 12:59 pm

As part of your fertility treatment, you may have to decide whether to transfer one embryo or more into your uterus with the hopes that they will properly implant and continue to a successful pregnancy. There are risks with each option, but it is important to fully understand the consequences of each decision so that you can make the right choice. Why Transfer More than One Embryo? If you are under 37 and otherwise healthy with no history of unsuccessful implantation, it’s likely that a single embryo transfer will be recommended. This is because multiple pregnancies are associated with higher morbidity for both the mother and foetus, and developmental problems due to prematurity. In most instances, your fertility care provider... View Article

What Happens After an Embryo Transfer?

May 31, 2017 10:17 am

Once embryos are transferred into the uterus, it typically takes 10 days until hCG levels are high enough to detect on a pregnancy test. However, many of our patients prefer to know what should be happening at each day so they can imagine the progress and look forward to that final day when they can see if the treatment has been successful. In some cases, patients experience a false negative on day 10 and it is always worth taking additional pregnancy test 2-4 days afterwards. Day by Day After a 5-Day Transfer Once your embryos have been transferred, you are essentially waiting for them to implant and for certain hormone levels to rise to order to sustain the pregnancy.

PTID and the Importance of Therapy During Fertility Treatments

May 24, 2017 10:06 am

Infertility is stressful for the majority of couples – the combination of wanting to be parents with sometimes intense hormonal changes, treatment schedules, and financial pressures, can make conception attempts increasingly upsetting. Rather than soldiering through, it’s essential that couples speak openly about these pressures and try to work through them to ensure good mental health and to even improve chances of success by reducing stress and the harmful hormonal changes that it can bring about. PTID: Post Traumatic Infertility Disorder In some rare cases, patients may develop something called PTID after failed pregnancy attempts or multiple treatment cycles – in some cases, the symptoms continue even after a successful pregnancy and birth. Many of the symptoms are normal for... View Article

What Causes Age-Related Infertility?

May 17, 2017 9:45 am

Female age is one of the most important factors to consider when making an infertility diagnosis and suggesting treatments. The deterioration in both egg quantity and quality make it significantly more difficult for a woman to conceive in her 40s compared to her 20s. How Fertility Changes with Age There are a number of different ways that age affects fertility. Women do not produce eggs over time – they are born with a finite number of eggs and cannot produce more. As women age, the number of eggs available quickly decreases, so fertility begins to decline in the mid- 30s. Over time, ovulation also slows down and happens less frequently in preparation for menopause. This effect can occasionally begin as... View Article

Can Diet Improve Fertility?

May 3, 2017 3:51 pm

One of the most common questions we are asked by patients is whether they can change their diet or add supplements to improve their chances of conceiving. The answer is complex and largely depends on the individual’s lifestyle, but the short version is that improving your overall health and lifestyle should have a positive effect on your fertility. However, if you already have a good diet, exercise regularly, and are not overweight these changes are likely to only have a limited impact. One of the times when diet can make the biggest impact on your fertility is when you are actively trying to conceive (rather than preparing for treatment). Here is a guide to help you maximise your chances of... View Article

How Many Cycles of IVF Do Patients Need?

April 19, 2017 8:46 am

Should Patients Plan for Several IVF Cycles or 1 Really Complicated One? Roughly 3.5 million people in the UK have difficulty with conceiving a child, equating to one in seven couples. This can be caused by a wide range of factors from age to body weight to smoking and drinking and a whole range of other conditions. Most couples pursue professional advice after around a year or two of trying and failing to conceive. Both the female and male partner will be tested in order to help diagnose the causes of infertility and determine what the best course of action is. What is IVF? In-Vitro Fertilisation (IVF) is one of the most effective tools for couples suffering with infertility. The... View Article

How Does the Thyroid Gland Affect Fertility?

April 10, 2017 4:35 pm

The thyroid gland is shaped like a butterfly, sitting low on the front of your neck. The hormones secreted by the thyroid gland influence factors such as metabolism, growth and body temperature. However, on occasion, the thyroid gland can produce too much or too little thyroid hormone and cause complications for couples hoping to start a family. Hypothyroidism and Fertility If a woman has an under-active thyroid condition (hypothyroidism) that is left untreated, her ability to conceive a baby will become hindered. She will likely experience heavier or prolonged periods or even no periods at all. This can cause anaemia. Luckily, the problems with the thyroid that interfere with pregnancy can be treated easily. By taking medication, the thyroid hormone... View Article

Scientists Have Created Mouse Embryos From Stem Cells

March 11, 2017 10:27 am

This is a story that has been reported by the BBC earlier in March and refers to the creation of embryos from stem cells. It is related to the ongoing debate about research into human embryos in laboratories. The law dictates that such embryos may only be grown for a maximum of 14 days and there is debate about whether that should be changed to 28 days. See elsewhere on this website for more on this. The 14-day restrictions apply to human embryos and not mouse embryos so discoveries from the mouse embryo research could give insights into how human embryos develop. Can Fertility Clinics Grow Human Embryos From Stem Cells? This is the question that people may infer from... View Article

Stress and Fertility

Don’t be too hopeful for starting a family if you are shift worker and the clocks have just gone forward for British Summer Time, at least according to a couple of studies published this month! Putting The Clocks Forward May Affect Fertility Doctors in America studying miscarriage rates have found a surprising rise in the number miscarriages in the three weeks following the clocks going forward – which is on the 26th of March this year. A study of 1654 IVF cycles over three years found a 24.3% miscarriage rate in this period as compared to a 15.5% rate over the whole of spring. The miscarriage rate in autumn is reported at 17.1%. So, is this just coincidence or perhaps... View Article

3-Parent Babies: What Does This Mean?

February 9, 2017 5:37 pm

Babies are now being born after mitochondrial donation Doctors in the Ukraine recently announced the birth of a baby girl following the use of a technique called pronuclear transfer, which involves using the mitochondrial DNA from third woman instead of the mitochondrial DNA which existed in the egg of the baby’s mother. Last year, in what is thought to be the world’s first, a baby was born in Mexico after his parents used a different mitochondrial donation technique. This was carried out by an American doctor and, somewhat alarmingly, he was quoted as saying that it took place in Mexico because “there are no rules”. Why donate mitochondria? Babies are born with a mixture of the DNA from their parents.... View Article
