The severity or complexity of infertility for you and your partner as a whole is also critical. Generally, patients are characterized as “subfertile” if there is only one infertility factor such as mild endometriosis, which can be improved through surgeries like laparoscopy. However, if both partners contribute infertility factors or one partner has multiple infertility factors, the chance of IVF success is significantly decreased.
In IVF, a woman is given more medications to develop lots of eggs. Ideally, they develop around 15 mature eggs. The eggs are removed from the ovaries, fertilized and developed in a lab for a number of days, and subsequently put back into the uterus as an early-stage embryo. While this may sound like a relatively minor difference, it leads to leads to a large number of noteworthy differences.

Artificial insemination, including intracervical insemination and intrauterine insemination of semen. It requires that a woman ovulates, but is a relatively simple procedure, and can be used in the home for self-insemination without medical practitioner assistance.[171] The beneficiaries of artificial insemination are women who desire to give birth to their own child who may be single, women who are in a lesbian relationship or women who are in a heterosexual relationship but with a male partner who is infertile or who has a physical impairment which prevents full intercourse from taking place.
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.
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.
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.
Every woman is born with a set number of eggs, which declines as she ages. To get pregnant, an egg released from a woman’s ovaries must be fertilized by sperm, travel down the fallopian tube, and attach to the side of her uterus. At any stage along the way, a problem may occur, resulting in a case of infertility. For women, the most common causes of infertility are primary ovarian insufficiency (early menopause), ovulation disorders affecting egg release, uterine or cervical abnormalities, endometriosis (where tissue grows outside of the uterus), fallopian tube blockage or damage, polycystic ovary syndrome, and various hormonal imbalances. Certain cancers and their treatments can also negatively impact a woman’s fertility.
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.[166] 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.[166] 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.[167] As of 2015, more than 1 million babies had been born utilising IVF technologies.[27]
The Rand Consulting Group has estimated there to be 400,000 frozen embryos in the United States in 2006.[83] The advantage is that patients who fail to conceive may become pregnant using such embryos without having to go through a full IVF cycle. Or, if pregnancy occurred, they could return later for another pregnancy. Spare oocytes or embryos resulting from fertility treatments may be used for oocyte donation or embryo donation to another woman or couple, and embryos may be created, frozen and stored specifically for transfer and donation by using donor eggs and sperm. Also, oocyte cryopreservation can be used for women who are likely to lose their ovarian reserve due to undergoing chemotherapy.[84]

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 contrast, a study in 2016 compared outcomes of IVF and ICSI in patients with unexplained infertility and normal semen quality and showed promising results using ICSI 3. It was found that ICSI oocytes (84.5%) had a significantly higher fertilization rate compared to those inseminated by conventional IVF (67.6%). Moreover, there were no cases of complete fertilization failure (CFF) in the ICSI group, but CFF occurred in 7.9% of the IVF group.
Embryo donation is the least expensive of the donor options. It's often cheaper than a regular IVF cycle. An embryo donor cycle costs anywhere between $5,000 and $7,000. This is assuming the embryo has already been created. (As opposed to choosing an egg donor and sperm donor and having the embryo created specifically for your cycle, which would be extremely expensive.)
While I’m not on the list to receive a Nobel Prize for mathematics any time soon, I do have enough understanding of how probabilities work to know that roulette isn’t a very viable long term career choice. Figuring that if I could make this costly error in analysis, there must be at least a few others out there that have, or will, make the same mistake as me…

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:
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.[142] 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.[143]
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.
Secondary infertility is the inability to become pregnant or carry a pregnancy to term after you’ve already had a baby, and it's more common than you might think, accounting for about 50 percent of infertility cases. In fact, more couples experience secondary infertility than primary infertility (infertility the first time around). It’s especially common in women who wait until their late 30s or even 40s, when fertility takes a nosedive, to have their second babies.
PGS screens for numeral chromosomal abnormalities while PGD diagnosis the specific molecular defect of the inherited disease. In both PGS and PGD, individual cells from a pre-embryo, or preferably trophectoderm cells biopsied from a blastocyst, are analysed during the IVF process. Before the transfer of a pre-embryo back to a woman's uterus, one or two cells are removed from the pre-embryos (8-cell stage), or preferably from a blastocyst. These cells are then evaluated for normality. Typically within one to two days, following completion of the evaluation, only the normal pre-embryos are transferred back to the woman's uterus. Alternatively, a blastocyst can be cryopreserved via vitrification and transferred at a later date to the uterus. In addition, PGS can significantly reduce the risk of multiple pregnancies because fewer embryos, ideally just one, are needed for implantation.
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 ultrasound is to check the size of your ovaries. Your doctor will also look for ovarian cysts. If there are cysts, your doctor will decide how to deal with them. Sometimes your doctor will just delay treatment for a week. Most cysts resolve on their own with time. In other cases, your doctor may aspirate the cyst (suck out the fluid) with a needle.
Typically, genetic parents donate the eggs to a fertility clinic or where they are preserved by oocyte cryopreservation or embryo cryopreservation until a carrier is found for them. Typically the process of matching the embryo(s) with the prospective parents is conducted by the agency itself, at which time the clinic transfers ownership of the embryos to the prospective parents.[89]
In the United States, women seeking to be an embryo recipient undergo infectious disease screening required by the U.S. Food and Drug Administration (FDA), and reproductive tests to determine the best placement location and cycle timing before the actual Embryo Transfer occurs. The amount of screening the embryo has already undergone is largely dependent on the genetic parents' own IVF clinic and process. The embryo recipient may elect to have her own embryologist conduct further testing.
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.  
The industry has been accused of making unscientific claims, and distorting facts relating to infertility, in particular through widely exaggerated claims about how common infertility is in society, in an attempt to get as many couples as possible and as soon as possible to try treatments (rather than trying to conceive naturally for a longer time). This risks removing infertility from its social context and reducing the experience to a simple biological malfunction, which not only can be treated through bio-medical procedures, but should be treated by them.[104][105] Indeed, there are serious concerns about the overuse of treatments, for instance Dr Sami David, a fertility specialist, has expressed disappointment over the current state of the industry, and said many procedures are unnecessary; he said: "It's being the first choice of treatment rather than the last choice. When it was first opening up in late 1970s, early 80s, it was meant to be the last resort. Now it's a first resort. I think that it can harm women in the long run."[106] IVF thus raises ethical issues concerning the abuse of bio-medical facts to 'sell' corrective procedures and treatments for conditions that deviate from a constructed ideal of the 'healthy' or 'normal' body i.e., fertile females and males with reproductive systems capable of co-producing offspring.
After the retrieval procedure, you'll be kept for a few hours to make sure all is well. Light spotting is common, as well as lower abdominal cramping, but most feel better in a day or so after the procedure. You'll also be told to watch for signs of ovarian hyperstimulation syndrome, a side effect from fertility drug use during IVF treatment in 10% of patients.

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.[79] Co-treatment with GnRH agonists appears to improve outcomes,[79] by a live birth rate RD of +16% (95% confidence interval +10 to +22%).[80] On the other hand, growth hormone or aspirin as adjunctive medication in IVF have no evidence of overall benefit.[30]
