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.
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.

There’s an intense emotional response to hearing, “There is no apparent reason for your infertility”. It can be difficult, maddening and equally frustrating for both you and your partner. People who do find out a specific cause find their situations difficult, too, of course, but knowing the “whys” makes it more bearable. In cases of unexplained infertility, couples feel that one reason, one cause is lurking in a shadowy corner. It just hasn’t been uncovered yet.
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.
In the United States, overall availability of IVF in 2005 was 2.5 IVF physicians per 100,000 population, and utilisation was 236 IVF cycles per 100,000. 126 procedures are performed per million people per year. Utilisation highly increases with availability and IVF insurance coverage, and to a significant extent also with percentage of single persons and median income. In the US, an average cycle, from egg retrieval to embryo implantation, costs $12,400, and insurance companies that do cover treatment, even partially, usually cap the number of cycles they pay for. As of 2015, more than 1 million babies had been born utilising IVF technologies.
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:
• Women having irregular periods. Regular periods indicate that you are ovulating regularly. Eggs are produced through ovulation two weeks prior to the next period. Ovulation of the egg is essential for pregnancy, and any irregularity in this process leads to an inability to conceive. If you have irregular periods then it is better to get evaluated from a reproductive endocrinologist.
Gathering the eggs. Your doctor gives you an anesthetic and inserts an ultrasound probe through your vagina to look at your ovaries and identify the follicles. A thin needle is then inserted through the vaginal wall to remove the eggs from the follicles. Eight to 15 eggs are usually retrieved. You may have some cramping and spotting for a few days afterward, but most women feel better in a day or two.
Few American courts have addressed the issue of the "property" status of a frozen embryo. This issue might arise in the context of a divorce case, in which a court would need to determine which spouse would be able to decide the disposition of the embryos. It could also arise in the context of a dispute between a sperm donor and egg donor, even if they were unmarried. In 2015, an Illinois court held that such disputes could be decided by reference to any contract between the parents-to-be. In the absence of a contract, the court would weigh the relative interests of the parties.

The take home message of these studies is that when gonadotropins are given to this patient population at a dose that doesn’t put the patient at significant risk of twins (like the 75 units in the Huang study), they are no better than oral medications (clomid and letrozole) at producing successful pregnancies. This is important because clomid and letrozole are also cheaper to purchase (hundreds vs. thousands of dollars) and easier to administer (oral rather than injectable). For this reason, many clinics have moved away from using gonadotropins in IUI cycles.
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.
Fertility expert Zita West has noticed this increase at her London clinic. "The main reason," she explains, "is age. Women are having babies later." Exhaustion also plays a part. "The sleeplessness of life with a small child can't be underestimated," she says. "You might still be breastfeeding, you might be sharing a bed with a toddler, you might be holding down a job at the same time. Basically, there's not a lot of sex happening."
If you fit one of these profiles, your fertility team may agree that it makes sense to attempt IUI before considering IVF. Before you begin IUI, it’s good to have a conversation with your partner and doctor about how many cycles you want to attempt. Many people place a limit of three failed IUI cycles, but others may try up to six before moving on.
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.
A recent large population-based study collected data from almost 5000 European patients. According to preliminary results presented at the 2019 European Society of Human Reproduction and Embryology, there is no benefit from ICSI in non-male factor cases. Importantly, the study reported no benefit of using ICSI regardless of how many eggs are retrieved after ovarian stimulation. Therefore, having a low oocyte yield should not be a reason for choosing ICSI over IVF.
Sunni Muslim nations generally allow IVF between married couples when conducted with their own respective sperm and eggs, but not with donor eggs from other couples. But Iran, which is Shi'a Muslim, has a more complex scheme. Iran bans sperm donation but allows donation of both fertilised and unfertilised eggs. Fertilised eggs are donated from married couples to other married couples, while unfertilised eggs are donated in the context of mut'ah or temporary marriage to the father.
Ovarian stem cells: it is thought that women have a finite number of follicles from the very beginning. Nevertheless, scientists have found these stem cells, which may generate new oocytes in postnatal conditions. Apparently there are only 0.014% of them (this could be an explanation of why they were not discovered until now). There is still some controversy about their existence, but if the discoveries are true, this could be a new treatment for infertility.
In a lab, your eggs are mixed with sperm cells from your partner or a donor — this is called insemination. The eggs and sperm are stored together in a special container, and fertilization happens. For sperm that have lower motility (don’t swim as well), they may be injected directly into the eggs to promote fertilization. As the cells in the fertilized eggs divide and become embryos, people who work at the lab monitor the progress.
For couples who have no difficulty achieving a pregnancy, the natural chance of pregnancy per month of ovulation is largely dependent on the age of the woman. For women in their early 30s or younger, the natural pregnancy rate is about 20 to 25 percent per cycle. This drops off significantly through her mid-to late-30s; by her early 40s, the chance of pregnancy is about 5 percent per cycle. This age-related decrease is primarily due to a decline in the quality of the eggs within the ovaries.
4. IVF or In-Vitro Fertilization - IVF means eggs are collected and fertilized outside the body, in a laboratory. This is followed by transferring the embryos into the uterus. This advanced technology has resulted in many successful pregnancies in women who had lost hope. During IVF - In-Vitro Fertilization, women can choose to freeze their healthy eggs for future use.
High costs keep IVF out of reach for many developing countries, but research by the Genk Institute for Fertility Technology, in Belgium, claim to have found a much lower cost methodology (about 90% reduction) with similar efficacy, which may be suitable for some fertility treatment. Moreover, the laws of many countries permit IVF for only single women, lesbian couples, and persons participating in surrogacy arrangements. Using PGD gives members of these select demographic groups disproportionate access to a means of creating a child possessing characteristics that they consider "ideal," raising issues of equal opportunity for both the parents'/parent's and the child's generation. Many fertile couples now demand equal access to embryonic screening so that their child can be just as healthy as one created through IVF. Mass use of PGD, especially as a means of population control or in the presence of legal measures related to population or demographic control, can lead to intentional or unintentional demographic effects such as the skewed live-birth sex ratios seen in communist China following implementation of its one-child policy.
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.
Medical treatment of infertility generally involves the use of fertility medication, medical device, surgery, or a combination of the following. If the sperm are of good quality and the mechanics of the woman's reproductive structures are good (patent fallopian tubes, no adhesions or scarring), a course of ovulation induction maybe used. The physician or WHNP may also suggest using a conception cap cervical cap, which the patient uses at home by placing the sperm inside the cap and putting the conception device on the cervix, or intrauterine insemination (IUI), in which the doctor or WHNP introduces sperm into the uterus during ovulation, via a catheter. In these methods, fertilization occurs inside the body.
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.
Deciding whether to undergo in vitro fertilization, and how to try if the first attempt is unsuccessful, is an incredibly complicated decision. The financial, physical, and emotional toll of this process can be difficult. Speak with your doctor extensively to determine what your best options are and if in vitro fertilization is the right path for you and your family. Seek a support group or counselor to help you and your partner through this process.
Availability of IVF in England is determined by Clinical commissioning groups. The National Institute for Health and Care Excellence recommends up to 3 cycles of treatment for women under 40 years old with minimal success conceiving after 2 years of unprotected sex. Cycles will not be continued for women who are older than 40 years old. CCGs in Essex, Bedfordshire and Somerset have reduced funding to one cycle, or none, and it is expected that reductions will become more widespread. Funding may be available in "exceptional circumstances" – for example if a male partner has a transmittable infection or one partner is affected by cancer treatment. According to the campaign group Fertility Fairness at the end of 2014 every CCG in England was funding at least one cycle of IVF". Prices paid by the NHS in England varied between under £3,000 to more than £6,000 in 2014/5. In February 2013, the cost of implementing the NICE guidelines for IVF along with other treatments for infertility was projected to be £236,000 per year per 100,000 members of the population.
3-6 months of treatment with Clomid pills (clomiphene citrate) might improve fertility by as much as 2 times as compared to no treatment. This is a very low level infertility treatment. Infertility specialists do not usually recommend Clomid treatment( without insemination) for unexplained infertility for women over the age of about 35. Most fertility specialists do not use it (without IUI) on any couples with unexplained infertility. If a woman is already having regular periods and ovulating one egg every month, giving Clomid, which will probably stimulate the ovaries to release 2 or 3 eggs per month (instead of one) is not really fixing anything that is broken - and is not likely to be successful.
