Assess your preconception prep. Have you been on top of the preconception game or are you just too busy for baby-planning activities like charting and timing baby-making sex (or any sex for that matter)? Given that you have a little one underfoot, it's understandable if you're more exhausted than ever. It’s not easy for wannabe second-time parents to devote as much time and energy to TTC as they likely did on the first go-around, but it would be helpful to take a step back (and a hard look) at what's going on. Are your cycles still regular, or have there been any changes that might be hurting your chances for conception success? Have you been able to pinpoint ovulation with accuracy, or are you just having sex whenever (which would make conception less likely)? Getting back on track with tracking your fertility signs may be enough to put you back in the game.
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.
Certain kinds of IVF, in particular ICSI (first applied in 1991) and blastocyst transfer (first applied in 1984) have been shown to lead to distortions in the sex ratio at birth. ICSI leads to slightly more female births (51.3% female) while blastocyst transfer leads to significantly more boys (56.1% male) being born. Standard IVF done at the second or third day leads to a normal sex ratio.
An IUI procedure is the process of directly injecting sperm into the top of the uterus. This increases the odds of conception by reducing the distance the sperm must travel to meet the egg. That said, when most people talk about IUIs, they’re referring to the steps leading up to and after the actual procedure. An IUI treatment can be summarized into a few steps:
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.
The eggs are retrieved in a simple process which takes about 15-20 minutes and is carried out in the doctor’s office under light sedation. The ovaries are accessed through the vaginal cavity and each of the follicles containing an egg is punctured. The fluid containing the eggs is aspirated through a very fine needle. The patient rests for a brief time and can then go home with an escort. Usually, the patient feels back to normal the day after.
After your body releases an egg, the hormone progesterone kicks in to build and maintain the lining of the uterus. It makes your body temperature go up slightly. So taking your temperature with a basal thermometer every morning before you get out of bed can help you figure out if you ovulated. You can buy these thermometers at the drugstore. They're inexpensive, but they aren't as accurate as other ways of tracking ovulation.
Once the medications take their effect, your doctor will use a transvaginal ultrasound to guide a needle through the back wall of your vagina, up to your ovaries. She will then use the needle to aspirate the follicle, or gently suck the fluid and oocyte from the follicle into the needle. There is one oocyte per follicle. These oocytes will be transferred to the embryology lab for fertilization.
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.
Couples experiencing infertility have a range of treatment options. Women can take fertility drugs to stimulate ovulation, or undergo certain surgeries and procedures, like intrauterine insemination, which carefully places healthy sperm in the uterus right before an egg is released to increase the chances of fertilization. Men can also take fertility medication or undergo surgery to increase the chances of conception.
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.
Costs of IVF can be broken down into direct and indirect costs. Direct costs include the medical treatments themselves, including doctor consultations, medications, ultrasound scanning, laboratory tests, the actual IVF procedure, and any associated hospital charges and administrative costs. Indirect costs includes the cost of addressing any complications with treatments, patients' travel costs and lost hours of productivity. These costs can be exaggerated by the increasing age of the woman undergoing IVF treatment (particularly those over the age of 40), and the increase costs associated with multiple births. For instance, a pregnancy with twins can cost up to three times that of a singleton pregnancy.
Of course, if you have a history of infertility or any factors that might impede fertility, it makes sense to arm yourself with the right help right from the start. Once you make that appointment with a fertility specialist, you and your doctor will follow the same treatment plan that would be put into place if you were dealing with primary infertility.
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.
The best study in the field enrolled 750 women to receive clomid or letrozole, followed them for 5 courses of therapy and revealed that the group receiving letrozole had higher live birth rates and fewer multiple gestations. The data is of exceptional quality, and there’s no reason to believe the conclusion doesn’t also apply to the choice of drugs if these patients proceeded on to IUI.
In general, the cost of IVF is higher than for IUI, but IVF confers the highest pregnancy rates per cycle. It is impossible to put a precise figure on the two treatments for comparison as much will depend on your personal treatment program. You can see some ballpark figures on the website of the Society for Assisted Reproductive Technology. It also contains an overview of the differences between IUI and IVF.
The diagnosis is one of exclusion — that is, one which is made only after all the existing tests have been performed and their results found to be normal. This is why the frequency of this diagnosis will depend upon how many tests are done by the clinic — the fewer the tests, the more frequent this diagnosis. And the better the tests, the more likely you are getting a diagnosis instead of being told it's "unexplained."
IUI is a procedure during which processed and concentrated motile sperm are inserted directly into a woman’s uterus. This procedure is timed according to a woman’s ovulation, and may be performed one to two times in the days immediately following the detection of ovulation. After ovulation a woman’s egg is picked up by the fallopian tube and waits there for the sperm. Since the IUI procedure deposits higher concentrations of good quality sperm close to where the egg is waiting, the chances that the egg and sperm will find one another are increased.
If IVF were to involve the fertilisation of only a single egg, or at least only the number that will be implanted, then this would not be an issue. However, this has the chance of increasing costs dramatically as only a few eggs can be attempted at a time. As a result, the couple must decide what to do with these extra embryos. Depending on their view of the embryo's humanity or the chance the couple will want to try to have another child, the couple has multiple options for dealing with these extra embryos. Couples can choose to keep them frozen, donate them to other infertile couples, thaw them, or donate them to medical research. Keeping them frozen costs money, donating them does not ensure they will survive, thawing them renders them immediately unviable, and medical research results in their termination. In the realm of medical research, the couple is not necessarily told what the embryos will be used for, and as a result, some can be used in stem cell research, a field perceived to have ethical issues.
Undergo minor surgery to retrieve eggs. Following a round of injections, your doctor will determine the best date to retrieve eggs from the follicles of your ovaries. If you choose to use donor eggs, the retrieval process will occur with the donor, or the frozen eggs may be collected and used. A partner’s sperm or donor sperm will also be collected.
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.
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.
Luteal support is the administration of medication, generally progesterone, progestins, hCG, or GnRH agonists, and often accompanied by estradiol, to increase the success rate of implantation and early embryogenesis, thereby complementing and/or supporting the function of the corpus luteum. A Cochrane review found that hCG or progesterone given during the luteal phase may be associated with higher rates of live birth or ongoing pregnancy, but that the evidence is not conclusive. Co-treatment with GnRH agonists appears to improve outcomes, by a live birth rate RD of +16% (95% confidence interval +10 to +22%). On the other hand, growth hormone or aspirin as adjunctive medication in IVF have no evidence of overall benefit.
