For women, problems with fertilisation arise mainly from either structural problems in the Fallopian tube or uterus or problems releasing eggs. Infertility may be caused by blockage of the Fallopian tube due to malformations, infections such as chlamydia or scar tissue. For example, endometriosis can cause infertility with the growth of endometrial tissue in the Fallopian tubes or around the ovaries. Endometriosis is usually more common in women in their mid-twenties and older, especially when postponed childbirth has taken place.[55]
Studies have indicated that IVF mothers show greater emotional involvement with their child, and they enjoy motherhood more than mothers by natural conception. Similarly, studies have indicated that IVF father's express more warmth and emotional involvement than fathers by adoption and natural conception and enjoy fatherhood more. Some IVF parents become overly involved with their children.[136]

Although menopause is a natural barrier to further conception, IVF has allowed women to be pregnant in their fifties and sixties. Women whose uteruses have been appropriately prepared receive embryos that originated from an egg of an egg donor. Therefore, although these women do not have a genetic link with the child, they have a physical link through pregnancy and childbirth. In many cases the genetic father of the child is the woman's partner. Even after menopause the uterus is fully capable of carrying out a pregnancy.[109]


Treatment with Clomid tablets plus IUI improves fertility rates. For unexplained infertility, studies have shown that for women under 35, monthly success rates for Clomid plus insemination are about 10% per cycle. This pregnancy rate holds up for about 3 tries and the success rate is considerably lower after that. More about success rates with IUIs is on the insemination page and on the Clomid for unexplained infertility page. The insemination component boosts fertility more than the Clomid does - but success rates are higher when both are used together.
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.
In some cases, laboratory mix-ups (misidentified gametes, transfer of wrong embryos) have occurred, leading to legal action against the IVF provider and complex paternity suits. An example is the case of a woman in California who received the embryo of another couple and was notified of this mistake after the birth of her son.[94] This has led to many authorities and individual clinics implementing procedures to minimise the risk of such mix-ups. The HFEA, for example, requires clinics to use a double witnessing system, the identity of specimens is checked by two people at each point at which specimens are transferred. Alternatively, technological solutions are gaining favour, to reduce the manpower cost of manual double witnessing, and to further reduce risks with uniquely numbered RFID tags which can be identified by readers connected to a computer. The computer tracks specimens throughout the process and alerts the embryologist if non-matching specimens are identified. Although the use of RFID tracking has expanded in the US,[95] it is still not widely adopted.[96]
Though there are some risk with older women pregnancies, there are some benefits associated with caesareans. A study has shown that births over 40 have a lower rate of birth trauma due to increased delivery by caesarean. Though caesarean is seen to benefit mothers over 40, there are still many risk factors to consider. Caesarean section may be a risk in the same way that gestational diabetes is.
The Latin term in vitro, meaning "in glass", is used because early biological experiments involving cultivation of tissues outside the living organism were carried out in glass containers, such as beakers, test tubes, or Petri dishes. Today, the scientific term "in vitro" is used to refer to any biological procedure that is performed outside the organism in which it would normally have occurred, to distinguish it from an in vivo procedure (such as in vivo fertilisation), where the tissue remains inside the living organism in which it is normally found.
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 can have a profound impact on one’s mental health. When men and women find out that they can’t conceive, they may experience the same painful emotions as anyone coping with grief or profound loss. Common reactions include shock, frustration, grief, anger, decreased self-esteem, anxiety, and depression, but feelings about infertility can vary greatly depending on the source of the problems. Men, in particular, find it far easier to deal with a partner’s infertility than with their own.
In 2006, Canadian clinics reported a live birth rate of 27%.[11] Birth rates in younger patients were slightly higher, with a success rate of 35.3% for those 21 and younger, the youngest group evaluated. Success rates for older patients were also lower and decrease with age, with 37-year-olds at 27.4% and no live births for those older than 48, the oldest group evaluated.[12] Some clinics exceeded these rates, but it is impossible to determine if that is due to superior technique or patient selection, since it is possible to artificially increase success rates by refusing to accept the most difficult patients or by steering them into oocyte donation cycles (which are compiled separately). Further, pregnancy rates can be increased by the placement of several embryos at the risk of increasing the chance for multiples.
Most couples develop a willingness to conceive a child at some point in their life. Generally, couples conceive within the first year, and around 7% of couples conceive in the second year. The inability to conceive within 12 months is defined as infertility. It is recommended to seek help from a reproductive endocrinologist if you are unable to conceive within 12 months. Our modern technology in healthcare has opened a lot of options for women who are facing infertility issues.

Time. The factor of time cuts both ways when you are weighing up these two options. IUI is a much shorter process than IVF, so if your first cycle is successful, it could be the quickest route to bringing home a baby. However, because of the gap in success rates between the two treatments, some patients in their late 30s to early 40s may get pregnant faster by going directly to IVF rather than waiting until they have had several failed IUI cycles.
In the US, up to 20% of infertile couples have unexplained infertility. In these cases abnormalities are likely to be present but not detected by current methods. Possible problems could be that the egg is not released at the optimum time for fertilization, that it may not enter the fallopian tube, sperm may not be able to reach the egg, fertilization may fail to occur, transport of the zygote may be disturbed, or implantation fails. It is increasingly recognized that egg quality is of critical importance and women of advanced maternal age have eggs of reduced capacity for normal and successful fertilization. Also, polymorphisms in folate pathway genes could be one reason for fertility complications in some women with unexplained infertility.[59] However, a growing body of evidence suggests that epigenetic modifications in sperm may be partially responsible.[60][61]
If you're overweight or obese, losing weight can boost your chances of getting pregnant. A study found that women whose body mass index (BMI) was above normal took twice as long to get pregnant as those with a normal BMI. But a drop in weight of 5%-10% can dramatically improve ovulation and pregnancy rates. Obesity can also cause infertility and low testosterone in men. Being significantly underweight can also lead to infertility.
Intrauterine insemination is less successful if the cause of infertility involves decreased egg quality, diseased Fallopian tubes, or endometriosis. IUI treatment cannot improve the quality of the eggs within the ovaries or repair damaged anatomical structure. As with advanced age, it may be advisable to move to IVF earlier in the treatment timeline with these diagnoses.
Our team here at the Center for Human Reproduction has recently developed an infographic explaining one of the most common causes of female infertility: unexplained infertility. This diagnosis is given to 30% of infertility cases and yet, we believe it really is a non-diagnosis. In our clinical experience, with proper testing, up to 90% of unexplained infertility diagnoses can be attributed to treatable causes.
The main durations of embryo culture are until cleavage stage (day two to four after co-incubation) or the blastocyst stage (day five or six after co-incubation).[71] Embryo culture until the blastocyst stage confers a significant increase in live birth rate per embryo transfer, but also confers a decreased number of embryos available for transfer and embryo cryopreservation, so the cumulative clinical pregnancy rates are increased with cleavage stage transfer.[30] Transfer day two instead of day three after fertilisation has no differences in live birth rate.[30] There are significantly higher odds of preterm birth (odds ratio 1.3) and congenital anomalies (odds ratio 1.3) among births having from embryos cultured until the blastocyst stage compared with cleavage stage.[71]
Connect with your partner. Remember that he is also coping with secondary infertility along with you, and while your partner may be dealing with it differently, it can be extremely helpful to check in with each other emotionally. Set aside some time to talk about how your infertility problems are affecting each of you — that can help you both work through your emotions. Tired of talking about infertility or channeling all your collective energy into that second pregnancy? Plan a date night — totally unrelated to any baby-making duties. Since secondary infertility problems can take a toll on any relationship, date nights are needed now more than ever to keep the love and fun flowing. An added bonus: Since less stress often improves fertility, enjoying just being a couple could even increase your odds of achieving that second pregnancy.

Primary infertility is defined as the absence of a live birth for women who desire a child and have been in a union for at least 12 months, during which they have not used any contraceptives.[14] The World Health Organisation also adds that 'women whose pregnancy spontaneously miscarries, or whose pregnancy results in a still born child, without ever having had a live birth would present with primarily infertility'.[14]
With each year that passes, your chances of conceiving decrease significantly, says Julie Tan, M.D., a gynecologist at the Cleveland Clinic Center for Reproductive Medicine, in Ohio. Sometimes even doctors downplay infertility, she notes. Most experts recommend seeing your doc after a year of unsuccessful unprotected sex if you're under age 35 and after six months if you're over 35. But if you're worried sooner, speak up. "If it's been three months and you're concerned, it's not too early to get evaluated, even though it may be premature to treat," explains Dr. Grifo. "Waiting a year to find out there's an issue with sperm count or egg supply can lead to a lot of heartache." You can start with your primary-care doc or ob-gyn but if you're not pregnant after a few months or feel your doctor isn't taking the situation seriously, see a fertility specialist.
For women, intake of antioxidants (such as N-acetyl-cysteine, melatonin, vitamin A, vitamin C, vitamin E, folic acid, myo-inositol, zinc or selenium) has not been associated with a significantly increased live birth rate or clinical pregnancy rate in IVF according to Cochrane reviews.[30] The review found that oral antioxidants given to men in couples with male factor or unexplained subfertility may improve live birth rates, but more evidence is needed.[30]
Cancer. Although some early studies suggested there may be a link between certain medications used to stimulate egg growth and the development of a specific type of ovarian tumor, more-recent studies do not support these findings. There does not appear to be a significantly increased risk of breast, endometrial, cervical or ovarian cancer after IVF.
If a man and woman 35 or younger have had unprotected sex for at least 12 months (or six months if older than 35) without getting pregnant, they should suspect secondary infertility. This especially applies to women older than 30 who have experienced pelvic inflammatory disease, painful periods, irregular menstrual cycles or miscarriages, and to men with low sperm counts.
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]
Women are not always the source of a couple's infertility—in approximately one-third of cases, men may have difficulty with conception. In another third of cases, men are a contributing factor, along with female infertility and other problems. Men should be evaluated by a physician if there is a family history of infertility, if they have undergone cancer treatment, if they have small testicles, a swollen scrotum, or a low sperm count, or if they have any other testicular, prostate, or sexual problems.
In the US, up to 20% of infertile couples have unexplained infertility. In these cases abnormalities are likely to be present but not detected by current methods. Possible problems could be that the egg is not released at the optimum time for fertilization, that it may not enter the fallopian tube, sperm may not be able to reach the egg, fertilization may fail to occur, transport of the zygote may be disturbed, or implantation fails.

When weighing the options, the pros and cons of intrauterine insemination (IUI) and in vitro fertilization (IVF) will, of course, be explored fully in discussion with your physician. In general terms, you can expect IUI to be a simpler process, less invasive, and lower cost. Some fertility specialists recommend attempting one or more cycles of artificial insemination before moving to IVF but this does not apply to everyone. For example, for an older woman, to try artificial insemination first may take up valuable time and the recommendation could well be to move straight to IVF. But before you can compare the two treatments, you need to know what exactly you could expect from IVF.
Perhaps except for infertility in science fiction, films and other fiction depicting emotional struggles of assisted reproductive technology have had an upswing first in the later part of the 2000s decade, although the techniques have been available for decades.[72] Yet, the number of people that can relate to it by personal experience in one way or another is ever growing, and the variety of trials and struggles is huge.[72]

Are you infertile, or just having trouble getting pregnant? If you go to the doctor, here’s how a diagnosis of infertility will happen. “Infertility” is a term that describes when a couple is unable to conceive a child after a year of having sex without birth control. In women who are older than age 35, infertility… Read More »How Doctors Diagnose Infertility
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.

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.
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.
The percentage of cycles cancelled between egg retrieval and embryo transfer is an indication of failed fertilization. This figure is halved with ICSI as compared to conventional IVF, indicating that it can indeed improve fertilization when the sperm is at fault. However, there are no differences in pregnancy, miscarriage or live birth rates between conventional IVF and ICSI, indicating overall similar success rates1.
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.
