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?
The number to be transferred depends on the number available, the age of the woman and other health and diagnostic factors. In countries such as Canada, the UK, Australia and New Zealand, a maximum of two embryos are transferred except in unusual circumstances. In the UK and according to HFEA regulations, a woman over 40 may have up to three embryos transferred, whereas in the US, there is no legal limit on the number of embryos which may be transferred, although medical associations have provided practice guidelines. Most clinics and country regulatory bodies seek to minimise the risk of multiple pregnancy, as it is not uncommon for multiple embryos to implant if multiple embryos are transferred. Embryos are transferred to the patient's uterus through a thin, plastic catheter, which goes through her vagina and cervix. Several embryos may be passed into the uterus to improve chances of implantation and pregnancy.
Hashimoto's thyroiditis or chronic lymphocytic thyroiditis, is an autoimmune disorder causing inflammation of the thyroid gland. Hashimoto's thyroiditis is a type of hypothyroidism, and is the most common cause of hypothyroidism in the US. Symptoms of Hashimoto's thyroiditis may include dry skin, fatigue, weight gain, feeling cold, excessive sleepiness, dry skin, dry coarse hair, difficulty swallowing, a lump in the front of the throat, muscle cramps, mood changes, vague aches and pains, problems concentrating, leg swelling, constipation, and depression. There is no cure for Hashimoto’s thyroiditis. Diet changes, natural supplements, vitamins, or other natural products will not treat Hashimoto’s thyroiditis. Treatment for the autoimmune disorder is with thyroid hormone replacement therapy, which will be necessary for the rest of the person’s life.
Low weight: Obesity is not the only way in which weight can impact fertility. Men who are underweight tend to have lower sperm concentrations than those who are at a normal BMI. For women, being underweight and having extremely low amounts of body fat are associated with ovarian dysfunction and infertility and they have a higher risk for preterm birth. Eating disorders such as anorexia nervosa are also associated with extremely low BMI. Although relatively uncommon, eating disorders can negatively affect menstruation, fertility, and maternal and fetal well-being.
The NHS recommends that, after trying and failing to get pregnant for a year, you should see your doctor; if you are over 35, you should go after six months. Help is out there, if you want it, and takes many forms. West stresses the importance of investigating both the women and the men, "even if they have previously had a healthy sperm analysis because situations and lifestyles can change". There is also the alternative therapy route: acupuncture, hypnotherapy, reflexology, meditation. Or, if all else fails, you could, like me, go for in-vitro fertilisation (IVF).
Laboratories have developed grading methods to judge ovocyte and embryo quality. In order to optimise pregnancy rates, there is significant evidence that a morphological scoring system is the best strategy for the selection of embryos. Since 2009 where the first time-lapse microscopy system for IVF was approved for clinical use, morphokinetic scoring systems has shown to improve to pregnancy rates further. However, when all different types of time-lapse embryo imaging devices, with or without morphokinetic scoring systems, are compared against conventional embryo assessment for IVF, there is insufficient evidence of a difference in live-birth, pregnancy, stillbirth or miscarriage to choose between them. Active efforts to develop a more accurate embryo selection analysis based on Artificial Intelligence and Deep Learning are underway. Embryo Ranking Intelligent Classification Assistant (ERICA), is a clear example. This Deep Learning software substitutes manual classifications with a ranking system based on an individual embryo's predicted genetic status in a non-invasive fashion. Studies on this area are still pending and current feasibility studies support its potential.
The first step in finding the right treatment is to find out if there is an actual cause for unexplained infertility. Taking treatment helps to increase the chances of conceiving, and also makes it likelier that you will get pregnant sooner. The treatment of luteal-phase defects is as controversial as the diagnosis. They can be treated by using clomiphene, which may help by augmenting the secretion of FSH and thus improving the quality of the follicle (and therefore, the corpus luteum, which develops from it). Direct treatment with progesterone can also help luteal-phase abnormalities. Progesterone can be given either as injections or vaginal suppositories.
Success rates vary with the number of embryos transferred. However, transferring more and more embryos at one time does not increase the chance of live birth significantly, but may only increase the risk of a multiple pregnancy, and its associated risks. The impact of the number of embryos that are transferred also varies with the age of the woman.
A 2013 review and meta analysis of randomised controlled trials of acupuncture as an adjuvant therapy in IVF found no overall benefit, and concluded that an apparent benefit detected in a subset of published trials where the control group (those not using acupuncture) experienced a lower than average rate of pregnancy requires further study, due to the possibility of publication bias and other factors.
All major restrictions on single but infertile women using IVF were lifted in Australia in 2002 after a final appeal to the Australian High Court was rejected on procedural grounds in the Leesa Meldrum case. A Victorian federal court had ruled in 2000 that the existing ban on all single women and lesbians using IVF constituted sex discrimination. Victoria's government announced changes to its IVF law in 2007 eliminating remaining restrictions on fertile single women and lesbians, leaving South Australia as the only state maintaining them.
I found that I couldn't avoid the sense that we were not yet all here, that there was a person missing. In one of those strange confluences, I was, at the same time, writing a novel about a woman who had just given birth. I was spending my days at the fertility clinic and my evenings writing about the strange, shadowy world of early motherhood. My husband, coming into my study and finding me in tears again, laid his hand gently on the manuscript and said, "Do you ever think that writing this book might not be helping?" But you don't choose the books; they choose you. And if I couldn't bring a baby into being in real life, I was damn well going to do it in fiction.
A genetic disorder. If you or your partner is at risk of passing on a genetic disorder to your child, you may be candidates for preimplantation genetic testing — a procedure that involves IVF. After the eggs are harvested and fertilized, they're screened for certain genetic problems, although not all genetic problems can be found. Embryos that don't contain identified problems can be transferred to the uterus.
Most women over 40 who try to get pregnant will have difficulty, and fertility over age 44 is rare - even in women who are ovulating regularly every month. The point is that the older the female partner, the more likely that there is an egg related issue causing the fertility problem. Unfortunately, there is currently no specific test for "egg quality".
Ovarian hyperstimulation is the stimulation to induce development of multiple follicles of the ovaries. It should start with response prediction by e.g. age, antral follicle count and level of anti-Müllerian hormone. The resulting prediction of e.g. poor or hyper-response to ovarian hyperstimulation determines the protocol and dosage for ovarian hyperstimulation.
Secondary infertility is the inability to conceive a child or carry a pregnancy to full term after previously giving birth. To classify as secondary infertility, the previous birth must have occurred without help from fertility medications or treatments, like in vitro fertilization. Secondary infertility typically is diagnosed after trying unsuccessfully to conceive for six months to a year. A related condition is recurrent pregnancy loss where patients and couples are able to conceive but are unable to carry to term.
In humans, infertility is the inability to become pregnant after one year of intercourse without contraception involving a male and female partner. There are many causes of infertility, including some that medical intervention can treat. Estimates from 1997 suggest that worldwide about five percent of all heterosexual couples have an unresolved problem with infertility. Many more couples, however, experience involuntary childlessness for at least one year: estimates range from 12% to 28%. Male infertility is responsible for 20–30% of infertility cases, while 20–35% are due to female infertility, and 25–40% are due to combined problems in both parts. In 10–20% of cases, no cause is found. The most common cause of female infertility is ovulatory problems, which generally manifest themselves by sparse or absent menstrual periods. Male infertility is most commonly due to deficiencies in the semen, and semen quality is used as a surrogate measure of male fecundity.
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.
Today, with assisted-reproductive technology, the chance of successful treatment is very good. Intrauterine insemination with superovulation is the simplest approach since it increases the chances of the egg and sperm meeting, but some patients may also need GIFT and IVF. IVF can be helpful because it provides information about the sperm's fertilizing ability; GIFT, on the other hand, has a higher pregnancy rate and is applicable in these patients since they have normal fallopian tubes.
Problems with the uterus: There are many conditions related to the uterus that can cause secondary infertility. Scarring can occur during a dilation and curettage (D&C) or Cesarean delivery that can create adhesions inside the uterus that interfere with future pregnancies Fibroids or polyps are benign (non-cancer) growths inside the uterus that can impair pregnancy. A retained placenta can cause infection and uterine scarring.
Your doctor will also monitor whether or not the treatment led to a multiple pregnancy. IVF has a higher risk of conceiving multiples, and a multiple pregnancy carries risks for both the mother and the babies. Risks of a multiple pregnancy include premature labor and delivery, maternal hemorrhage, C-section delivery, pregnancy induced high blood pressure, and gestational diabetes.
Risk of multiples. IUI with fertility medication carries a significant risk of multiple pregnancies, including higher-order multiples (triplets or more). A good clinic will carefully monitor your follicles to make sure that only a safe number are mature before the IUI, but they cannot entirely eliminate the risk. Recent advances in IVF (including blastocyst transfer) mean that most modern fertility clinics now transfer only one or two embryos per IVF cycle. As a result, the risk of multiple pregnancies for IVF patients is much lower than it used to be.
One of the worst parts of infertility – or the fear of being infertile – is friends and family members getting pregnant accidentally! “Today, my child-hating friend who vowed never to have kids no matter what, announced that she’s pregnant,” says Charity. “I’ve had three IVF (in vitro fertilization) cycles, spent $90,000 in fertility treatments, and still can’t conceive a baby. WTF?”
Problems in the quantity or quality of eggs: Women are born with a limited supply of eggs and are unable to create new eggs after birth. As women approach their 40s and beyond, the numbers of eggs left in their ovaries decrease, and the remaining eggs have a higher chance of having chromosomal problems. For women where age isn’t a concern, there are other reasons that they might have a low number of good quality eggs, including autoimmune or genetic conditions and prior surgery or radiation.
The treatment options for unexplained infertility are several and the treatment results are promising. Expectant management can be recommended if the woman is under 28-30 years of age and the infertility duration is less than 2-3 years. In vitro fertilization (IVF) has revolutionized the treatment of infertile couples, as well as profoundly increasing the basic understanding of human reproduction. IVF can be used as both a diagnostic and a therapeutic tool in couples with unexplained infertility. The pregnancy rates with IVF are good, at 40% per treatment cycle. In addition, the outcome of pregnancies among women with unexplained infertility is generally comparable to that of spontaneous and other pregnancies using assisted reproductive technologies.
