The Human Fertilisation and Embryology Authority said in September 2018 that parents who are limited to one cycle of IVF, or have to fund it themselves, are more likely choose to implant multiple embryos in the hope it increases the chances of pregnancy. This significantly increases the chance of multiple births and the associated poor outcomes, which would increase NHS costs. The president of the Royal College of Obstetricians and Gynaecologists said that funding 3 cycles was "the most important factor in maintaining low rates of multiple pregnancies and reduce(s) associated complications".[165]
During the second half of your menstrual cycle, the hormone progesterone kicks in to help prepare the lining of your uterus for a fertilized egg. If the egg isn't fertilized and doesn't implant, it disintegrates, progesterone levels fall, and about 12 to 16 days later, the egg -- along with blood and tissues from the lining of the uterus -- is shed from the body. That process is menstruation. It usually lasts 3 to 7 days.
IVF success rates are the percentage of all IVF procedures that result in a favourable outcome. Depending on the type of calculation used, this outcome may represent the number of confirmed pregnancies, called the pregnancy rate, or the number of live births, called the live birth rate. The success rate depends on variable factors such as maternal age, cause of infertility, embryo status, reproductive history, and lifestyle factors.
Statistically, the biggest decline in live births happens between the ages of 40 and 42+. In other words, a woman who has just turned 40 has a much higher chance of conceiving and delivering a baby than a woman who has just turned 42. Of course, these numbers and trends concern women using their own eggs. With donor eggs, consider the age of the woman at the time the eggs were harvested and use that age.

Women are born with about 1 million to 2 million eggs but release only 300 to 400 through ovulation during their lifetimes. Usually, you release just one each month. The egg travels along one of the two fallopian tubes that connect your ovaries to your uterus. If the timing is right, sperm may fertilize it on its way to the uterus. If fertilization doesn't happen within 24 hours of the egg leaving the ovary, the egg dissolves. Sperm can live for about 3 to 5 days, so knowing when you are ovulating can help you and your partner plan sex for when you're most likely to conceive.
Infertility is, in all its forms, a most private, hidden anguish. Nobody wants to discuss the finer points of their reproductive system in public. And the desire to have a child can, if thwarted, be so overwhelming that just a glimpse from a car window of someone with a BabyBjorn can be enough to produce such a flood of tears that you have to pull over. How can you possibly articulate that level of pain to the casual inquirer?
Dr. Gorka Barrenetxea provides us with a practical case of secondary infertility that occurs more commonly than one may think. A couple, throughout their lifetime, can have children with 20, 25, 30 and 35 years, but when they decide to have a second or third child, they may encounter trouble conceiving due to the passage of time itself, Dr. Barrenetxea states.
Odds of multiples. Because more than one embryo may be placed in your uterus, your chance of having twins or more is about 20 percent. Though many couples consider this a blessing, multiple fetuses increase your risk of miscarriage and other complications, such as preterm labor. Some doctors will advise you to consider selective reduction if three or more embryos implant successfully. This is a serious decision with major emotional and psychological consequences. IVF researchers are working on techniques to prevent multiple fetuses.
A risk of ovarian stimulation is the development of ovarian hyperstimulation syndrome, particularly if hCG is used for inducing final oocyte maturation. This results in swollen, painful ovaries. It occurs in 30% of patients. Mild cases can be treated with over the counter medications and cases can be resolved in the absence of pregnancy. In moderate cases, ovaries swell and fluid accumulated in the abdominal cavities and may have symptoms of heartburn, gas, nausea or loss of appetite. In severe cases patients have sudden excess abdominal pain, nausea, vomiting and will result in hospitalisation.
Apart from poor egg quality at advanced maternal age, older women are also less likely to respond to ovarian stimulation hormones that cause the release of multiple eggs. Being able to produce a dozen of eggs significantly increases the odds of success. It allows your fertility practitioner to choose the egg with normal genetic makeup and best likelihood of implantation. In both nature and IVF, not all eggs are suitable to produce a pregnancy. Ideally, you would produce 8-15 eggs after ovarian hyperstimulation so that some of them are genetically normal and perfectly matured.

If a couple has been actively trying for over a year, it may be time to consider seeing a specialist. One thing we hear time and time again from our Glow Fertility Program partner physicians is that they wish their patients would come in sooner. Seeing a specialist as soon as you suspect you may have a problem trying to conceive can save you both time and money.
Ovarian hyperstimulation syndrome (OHSS) occurs in 10% of women going through IVF treatment. For most women, symptoms will be mild, and they will recover easily. For a small percentage, OHSS can be more serious and may require hospitalization. Less than 1% of women going through egg retrieval will experience blood clots or kidney failure due to OHSS.
Oral drugs used to stimulate ovulation include clomiphene citrate and aromatase inhibitors. While taking these drugs, you will be monitored to see if and when ovulation occurs. This can be done by tracking your menstrual cycle or with an ovulation-predictor kit (an at-home urine test). You may be asked to visit your doctor for a blood test or ultrasound exam.

In the well-established fertility treatment of IVF, unlike IUI, the meeting of sperm and egg takes place outside the body, in the laboratory (in vitro). This gives fertility practitioners a lot more control over the selection of a genetically normal embryo that has the best chance of establishing a successful pregnancy. IVF is the fertility treatment with the highest likelihood of taking home a healthy baby. These are the stages involved in IVF:
That’s about the time frame women between the ages of 35 and 40 should give themselves, before discussing fertility concerns with their doctor. For women under 35, experts recommend trying for about a year—really trying, as in unprotected, well-timed intercourse—before having any testing or treatment; women over 40 may want to consult an obstetrician/gynecologist right away. See your doctor sooner than later if you’ve suffered multiple miscarriages, have a history of pelvic inflammatory disease (a serious complication of some STDs), or experience any other symptoms of infertility. Meanwhile, learn these infertility myths you don’t have to worry about.
It’s not because you just ate a whole lot of greasy food (myth!). Sudden, out-of-control acne could be blamed on fluctuating hormones (from your period or menopause), a whole lot of stress, or a medication side effect. It may also be a sign of polycystic ovarian syndrome. That’s because in women with PCOS, ovaries make more androgen—the “male hormone”—than normal. Elevated levels may lead to adult acne flare-ups, as well as excessive facial or body hair, and even male-patterned baldness. These natural acne remedies may help your skin.
IVF: During IVF, medications are usually taken for around 10 days to grow a large number of eggs. Once many eggs have developed, a procedure takes place where the eggs are removed from the ovaries. The eggs are then fertilized outside of the body in a lab. After growing for a few days in the lab, an embryo is transferred back into the woman’s uterus. 
The common thing that happens once learning about the unexplained infertility diagnosis is shifting blame or incurring guilt. You may feel a sense of individual responsibility for the news, and be concerned about the effects that this will have on your relationship and your current partner. Perhaps you feel like you waited too long to start a family or have anxiety finding the right parenting partner that you associate now with your infertility. Remember, it’s no one’s fault.

These time intervals would seem to be reversed; this is an area where public policy trumps science. The idea is that for women beyond age 35, every month counts and if made to wait another six months to prove the necessity of medical intervention, the problem could become worse. The corollary to this is that, by definition, failure to conceive in women under 35 isn't regarded with the same urgency as it is in those over 35.
While many cases of infertility remain unexplained, there may be answers in the epigenome. Unlike one’s genetic code, the epigenome is dynamic and can be modified by environmental factors and lifestyle choices. Fertility in many cases is a state which changes throughout one’s life. Given the lack of clear genetic or physiological causes of unexplained infertility, the epigenome is thought to be altered in this subset of patients. As a result, looking into the epigenetic basis of infertility can help clinicians inform treatment.
Within the Orthodox Jewish community the concept is debated as there is little precedent in traditional Jewish legal textual sources. Regarding laws of sexuality, religious challenges include masturbation (which may be regarded as "seed wasting"[129]), laws related to sexual activity and menstruation (niddah) and the specific laws regarding intercourse. An additional major issue is that of establishing paternity and lineage. For a baby conceived naturally, the father's identity is determined by a legal presumption (chazakah) of legitimacy: rov bi'ot achar ha'baal – a woman's sexual relations are assumed to be with her husband. Regarding an IVF child, this assumption does not exist and as such Rabbi Eliezer Waldenberg (among others) requires an outside supervisor to positively identify the father.[133] Reform Judaism has generally approved IVF.[129]
Men will need to have sperm testing. This involves giving a semen sample, which a lab will analyze for the number, size, and shape of the sperm. If the sperm are weak or damaged, a procedure called intracytoplasmic sperm injection (ICSI) may be necessary. During ICSI, a technician injects sperm directly into the egg. ICSI can be part of the IVF process.
For cases where donor sperm is required, the majority of patients use commercial sperm banks as their source of donor sperm. You can find out a lot about a potential donor before making your choice. For example, you can access information about the donor’s ethnic or racial background, education, and physical characteristics. It’s also reassuring to know that sperm banks always screen donors for sexually transmitted diseases (STDs) such as chlamydia, syphilis, gonorrhea, hepatitis, HIV, and others. The FDA and the Centers for Disease Control and Prevention (CDC) recommend that frozen semen from a licensed sperm bank be used in order to prevent STDs.
Ovarian reserve testing. To determine the quantity and quality of your eggs, your doctor might test the concentration of follicle-stimulating hormone (FSH), estradiol (estrogen) and anti-mullerian hormone in your blood during the first few days of your menstrual cycle. Test results, often used together with an ultrasound of your ovaries, can help predict how your ovaries will respond to fertility medication.
Progesterone elevation on the day of induction of final maturation is associated with lower pregnancy rates in IVF cycles in women undergoing ovarian stimulation using GnRH analogues and gonadotrophins.[23] At this time, compared to a progesterone level below 0.8 ng/ml, a level between 0.8 and 1.1 ng/ml confers an odds ratio of pregnancy of approximately 0.8, and a level between 1.2 and 3.0 ng/ml confers an odds ratio of pregnancy of between 0.6 and 0.7.[23] On the other hand, progesterone elevation does not seem to confer a decreased chance of pregnancy in frozen–thawed cycles and cycles with egg donation.[23]
Those fearful of conceiving with multiples should strongly consider IVF and only transferring one embryo at a time. In these circumstances, just 1% of pregnancies lead to twins, and triplets are even more rare. Alternatively, 8 - 30% of medicated IUI pregnancies lead to twins. Finally, the least preferable circumstance is do to IVF with multiple embryo transfer, where in women under 38 years of age, 30% of pregnancies culminate in a multiple birth.

When you know your menstrual cycle, you improve your chances of getting pregnant. The first phase starts with the first day of bleeding during your period. Your body releases hormones, like follicle-stimulating hormone (FSH), that make the eggs inside your ovaries grow. Between days 2 and 14, those hormones also help thicken the lining of your uterus to get ready for a fertilized egg. This is called the follicular stage.
IVF is a type of assisted reproductive technology used for infertility treatment and gestational surrogacy. A fertilised egg may be implanted into a surrogate's uterus, and the resulting child is genetically unrelated to the surrogate. Some countries have banned or otherwise regulate the availability of IVF treatment, giving rise to fertility tourism. Restrictions on the availability of IVF include costs and age, in order for a woman to carry a healthy pregnancy to term. IVF is generally not used until less invasive or expensive options have failed or been determined unlikely to work.
A woman's age is a major factor in the success of IVF for any couple. For instance, a woman who is under age 35 and undergoes IVF has a 39.6% chance of having a baby, while a woman over age 40 has an 11.5% chance. However, the CDC recently found that the success rate is increasing in every age group as the techniques are refined and doctors become more experienced.
Life isn’t fair – there’s no doubt about it. That’s why it helps to have faith in God, to know He loves you and wants you to have the best possible life. My husband and I can’t have children, and it was the most disappointing discovery of my life. Trusting God when you can’t get pregnant is not easy – especially if you’ve been trying to conceive for months or even years.
As a result, most patients need to undergo multiple cycles, and as we pointed out in a another lesson, no cycle is as likely to succeed as the first one. Below is data out of the UK published in the Journal of The American Medical Association that illustrates that after a few cycles most younger patients succeed with IVF but that is not necessarily true for older patients.
Addressing lifestyle issues is not meant to be a quick fix, and typically does not lead to instant success. However, with unexplained infertility every little bit counts, so don’t fret or give up. Do not assume just because the cause of infertility is unexplained, it is untreatable or there is no pathway to parenthood. When a specific cause is not determined for women, and male infertility has also been ruled out, our fertility specialist may begin a course of treatment to improve the chances of conception and pregnancy. The speed with which interventions are offered depends on each individual’s own needs and desires as determined by age and other factors.

As with any medical procedure, there are some risks to keep in mind. When choosing between IUI and IVF, the risk is certainly something to consider. The chances of experiencing either a miscarriage or multiples are concerns many have when deciding to undergo fertility treatments. So let’s take a look at the odds of either of these things occurring, plus a few other risks to be aware of.

Mutations to NR5A1 gene encoding Steroidogenic Factor-1 (SF-1) have been found in a small subset of men with non-obstructive male factor infertility where the cause is unknown. Results of one study investigating a cohort of 315 men revealed changes within the hinge region of SF-1 and no rare allelic variants in fertile control men. Affected individuals displayed more severe forms of infertility such as azoospermia and severe oligozoospermia.[27]
Post transfer – You’ll likely take progesterone and estrogen to improve implantation and pregnancy rates. If the transfer is successful, a blood pregnancy test will be positive in 10-14 days. From there, ultrasounds are used to ensure the implantation site as well as check for a heartbeat. The good news is that once a heartbeat is detected, the pregnancy has a 90-95% probability of the pregnancy resulting in a live birth.
Alana Stewart, who was conceived using donor sperm, began an online forum for donor children called AnonymousUS in 2010. The forum welcomes the viewpoints of anyone involved in the IVF process.[121] Olivia Pratten, a donor-conceived Canadian, sued the province of British Columbia for access to records on her donor father's identity in 2008.[122] "I'm not a treatment, I'm a person, and those records belong to me," Pratten said.[119] In May 2012, a court ruled in Pratten's favour, agreeing that the laws at the time discriminated against donor children and making anonymous sperm and egg donation in British Columbia illegal.[122]

Many people have never heard the term "secondary infertility"; fewer understand it. I discovered it a year into my struggle to conceive a second child and fell on it, amazed. What I was undergoing had a name! I wrote it down and immediately felt better, as if the phrase exuded a talismanic power that might protect me from the likes of my neighbour.

IVF success rates are the percentage of all IVF procedures that result in a favourable outcome. Depending on the type of calculation used, this outcome may represent the number of confirmed pregnancies, called the pregnancy rate, or the number of live births, called the live birth rate. The success rate depends on variable factors such as maternal age, cause of infertility, embryo status, reproductive history, and lifestyle factors.


Vzhledem k tomu, že vertikální přenos a vliv koronaviru SARS-CoV-2 na graviditu není dostatečně prozkoumán, mezinárodní odborné společnosti doporučují zvážit možná rizika spojená s těhotenstvím v oblastech zasažených onemocněním SARS-CoV-2. Z tohoto důvodu preferuje naše klinika zamražení získaných embryí a odložení transferu. Strategie léčby bude vždy posouzena individuálně ošetřujícím lékařem s ohledem na aktuální situaci v ČR a specifika léčeného páru.
