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.
Abdominal adhesions (scar tissue) bands of scar tissue that form between abdominal organs and tissues. Symptoms of abdominal adhesions are pelvic or abdominal pain. Abdominal adhesions on the intestines can cause bowel obstruction, which is a medical emergency. Treatment for abdominal adhesions is generally surgery to cut the adhesions away from the internal tissues and organs. There is no way to prevent abdominal adhesions.
Odds of multiples. Because more than one embryo may be placed in your uterus, your chance of having twins or more is about 20 percent. Though many couples consider this a blessing, multiple fetuses increase your risk of miscarriage and other complications, such as preterm labor. Some doctors will advise you to consider selective reduction if three or more embryos implant successfully. This is a serious decision with major emotional and psychological consequences. IVF researchers are working on techniques to prevent multiple fetuses.
Sometimes problems getting pregnant for a second or subsequent time are related to a complication that occurred in a prior pregnancy or prior to delivery (damage to the uterus, for instance). But most often, secondary infertility is caused by the same factors that would cause primary infertility — issues like advanced age, obesity, ovulation problems and so on.
Apart from poor egg quality at advanced maternal age, older women are also less likely to respond to ovarian stimulation hormones that cause the release of multiple eggs. Being able to produce a dozen of eggs significantly increases the odds of success. It allows your fertility practitioner to choose the egg with normal genetic makeup and best likelihood of implantation. In both nature and IVF, not all eggs are suitable to produce a pregnancy. Ideally, you would produce 8-15 eggs after ovarian hyperstimulation so that some of them are genetically normal and perfectly matured.
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.

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.
Embryos are transferred to the uterus. Embryos that have developed from the fertilization process will be placed in the uterus, normally 3 to 5 days after retrieval, so that they can embed. If this process is successful, pregnancy will occur and IVF is considered a success. If it’s not, you may use a frozen embryo that you have saved from a previous round of IVF to try again.
Other health related problems could also cause poor egg health, low ovarian reserve, or abnormal immunological responses, which can affect conception. Stress could also play a role. We all know that menstrual cycles can be altered during times of extreme duress- and this can be emotional, physical, or environmental stressors. In these instances, the first steps should be to avoid life stressors, maintain a healthy weight, routinely exercise, avoid smoking, and reduce alcohol intake, all of which may be contributing to unexplained infertility issues.
Progesterone elevation on the day of induction of final maturation is associated with lower pregnancy rates in IVF cycles in women undergoing ovarian stimulation using GnRH analogues and gonadotrophins.[23] At this time, compared to a progesterone level below 0.8 ng/ml, a level between 0.8 and 1.1 ng/ml confers an odds ratio of pregnancy of approximately 0.8, and a level between 1.2 and 3.0 ng/ml confers an odds ratio of pregnancy of between 0.6 and 0.7.[23] On the other hand, progesterone elevation does not seem to confer a decreased chance of pregnancy in frozen–thawed cycles and cycles with egg donation.[23]
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]
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.

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.
Secondary infertility (SI) is defined by doctors as the inability to conceive or carry to term a second or subsequent child. You may not have heard of it but you probably soon will, because it's on the increase. A US study revealed that, in 1995, 1.8 million women suffered from secondary infertility; in 2006, it was 3.3 million. SI now accounts for six out of 10 infertility cases.
With the exception of severe male infertility, 70% of the oocytes will become fertilized. In the case of severe male infertility, ICSI (pronounced ick-see) may be used to fertilize the eggs, instead of simply placing them in a culture dish. With ICSI, the embryologist will choose a healthy-looking sperm and inseminate the oocyte with the sperm using a special thin needle.
Fertility tourism is the practice of traveling to another country for fertility treatments.[citation needed] It may be regarded as a form of medical tourism. The main reasons for fertility tourism are legal regulation of the sought procedure in the home country, or lower price. In-vitro fertilization and donor insemination are major procedures involved.

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.[90] 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.
Since marriage is a contract between the wife and husband during the span of their marriage, no third party should intrude into the marital functions of sex and procreation. This means that a third party donor is not acceptable, whether he or she is providing sperm, eggs, embryos, or a uterus. The use of a third party is tantamount to zina, or adultery.
Another major cause of infertility in women may be the inability to ovulate. Malformation of the eggs themselves may complicate conception. For example, polycystic ovarian syndrome is when the eggs only partially develop within the ovary and there is an excess of male hormones. Some women are infertile because their ovaries do not mature and release eggs. In this case synthetic FSH by injection or Clomid (Clomiphene citrate) via a pill can be given to stimulate follicles to mature in the ovaries.
It is extremely difficult for those with unexplained infertility to know when to stop looking for a cause, to say “enough is enough.” You may feel you are entering a state of limbo. You may feel stuck unable to grieve and get on with other options because you hang on to those slender threads of hope that the cause of your infertility will be revealed in the next test or treatment. Your sadness may intensify as time passes and you find no medical or emotional resolution. Consider finding a Support Group or Mental Health Professional in your area.
There are multiple treatment options including using oral or injectable medications, intrauterine insemination (IUI), assisted reproductive technology using in vitro fertilization (IVF), or a combo of these solutions to help. A 2010 study called the FASTT trial indicated that in vitro fertilization might be the quickest and best route to pregnancy for couples with unexplained infertility.(4)

Many people of sub-Saharan Africa choose to foster their children to infertile women. IVF enables these infertile women to have their own children, which imposes new ideals to a culture in which fostering children is seen as both natural and culturally important. Many infertile women are able to earn more respect in their society by taking care of the children of other mothers, and this may be lost if they choose to use IVF instead. As IVF is seen as unnatural, it may even hinder their societal position as opposed to making them equal with fertile women. It is also economically advantageous for infertile women to raise foster children as it gives these children greater ability to access resources that are important for their development and also aids the development of their society at large. If IVF becomes more popular without the birth rate decreasing, there could be more large family homes with fewer options to send their newborn children. This could result in an increase of orphaned children and/or a decrease in resources for the children of large families. This would ultimately stifle the children's and the community's growth.[134]
Ovary stimulation. For eight to 14 days near the beginning of your menstrual cycle, you take a gonadotropin, a type of fertility drug that stimulates your ovaries to develop multiple mature eggs for fertilization (instead of just one). You also need to take a synthetic hormone like leuprolide or cetrorelix to keep your body from releasing the eggs too early.
When you know your menstrual cycle, you improve your chances of getting pregnant. The first phase starts with the first day of bleeding during your period. Your body releases hormones, like follicle-stimulating hormone (FSH), that make the eggs inside your ovaries grow. Between days 2 and 14, those hormones also help thicken the lining of your uterus to get ready for a fertilized egg. This is called the follicular stage.
There are multiple strategies for causing ovulation in clomid or letrozole resistant patients. Some of these include adding medications such as dexamethasone or metformin to the treatment regimen. Another approach is changing to gonadotropin injections. Rather than tricking the brain into sending a stronger signal to the ovaries to cause follicle recruitment, gonadotropins directly stimulate the ovary to recruit multiple follicles.

Endometriosis and infertility are often related, but treating this pelvic inflammatory disorder can improve your chances of pregnancy. Here’s a description of what causes endometriosis, the symptoms of endometriosis, and what to do if you suspect you have this pelvic disorder. According to Harvard Medical School, endometriosis is responsible for many cases of infertility, there… Read More »Endometriosis and Infertility – How a Pelvic Disorder Affects Pregnancy
Unlike the simpler process of artificial insemination -- in which sperm is placed in the uterus and conception happens otherwise normally -- IVF involves combining eggs and sperm outside the body in a laboratory. Once an embryo or embryos form, they are then placed in the uterus. IVF is a complex and expensive procedure; only about 5% of couples with infertility seek it out. However, since its introduction in the U.S. in 1981, IVF and other similar techniques have resulted in more than 200,000 babies.
Israel has the highest rate of IVF in the world, with 1657 procedures performed per million people per year. Couples without children can receive funding for IVF for up to two children. The same funding is available for women without children who will raise up to 2 children in a single parent home. IVF is available for women aged 18 to 45.[153] The Israeli Health Ministry says it spends roughly $3450 per procedure.
Pelvic inflammatory disease (PID) is the most common and serious complication of sexually transmitted diseases (STDs), aside from AIDS, among women. The signs and symptoms of pelvic inflammatory disease include: fever, vaginal discharge with a foul odor, abdominal pain, including pain during intercourse, and irregular vaginal bleeding. Pelvic inflammatory disease can scar the Fallopian tubes, ovaries, and related structures and lead to ectopic pregnancies, infertility, chronic pelvic pain, and other serious consequences. Pelvic inflammatory disease treatment includes several types of antibiotics.
The major complication of IVF is the risk of multiple births. This is directly related to the practice of transferring multiple embryos at embryo transfer. Multiple births are related to increased risk of pregnancy loss, obstetrical complications, prematurity, and neonatal morbidity with the potential for long term damage. Strict limits on the number of embryos that may be transferred have been enacted in some countries (e.g. Britain, Belgium) to reduce the risk of high-order multiples (triplets or more), but are not universally followed or accepted. Spontaneous splitting of embryos in the womb after transfer can occur, but this is rare and would lead to identical twins. A double blind, randomised study followed IVF pregnancies that resulted in 73 infants (33 boys and 40 girls) and reported that 8.7% of singleton infants and 54.2% of twins had a birth weight of less than 2,500 grams (5.5 lb).[35]
Coping with secondary fertility can be tough. Endless doctor appointments, tests, procedures, and medications. Sleepless nights. Time and energy away from your little one. Guilt over wanting another pregnancy when many women are struggling to have just that. Stress between you and your partner. Sadness when you get invited to yet another baby shower — and guilt for even feeling that way.

Generally, the best chance of pregnancy is when sex happens 1-2 days before ovulation. If you have a regular 28-day cycle, count back 14 days from when you expect your next period to start. Plan on having sex every other day around that time -- say, days 12 and 14.  Keep in mind that having sex every day may lower a man's sperm count. Your cycle may be longer or shorter, so an online ovulation calculator may help you figure out the likely day.
Next, we’ll look at data that compares PCOS patients who took clomid alone or clomid accompanied by IUI (no studies use letrozole, so we are forced to use a study with clomid). Clomid alone produced a 17% live birth rate after 3 cycles, while clomid plus IUI produced a 19% live birth rate. Investigators concluded there was no statistically significant difference.

Clomiphene citrate (Clomid, Serophene) is a medication commonly used for the treatment of women with ovulation disorders as reflected by infrequent or irregular menstrual cycles. Clomid is a pill taken orally for 5 to 7 days, typically on day 3 of a woman’s menstrual cycle to induce ovulation. Clomid works at the level of the brain and pituitary gland and facilitates the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH). FSH and LH, in turn, stimulate the ovaries to produce eggs and the ovarian hormones estradiol (E2) and progesterone (P4). The initial prescribed dosage of clomid is 50 to 100 mg (one or two tablets) daily at bedtime, or as prescribed by your physician.
For example, untreated Celiac disease may in some cases of unexplained infertility. A 2016 reanalysis of previous research studies have found that Celiac disease may be diagnosed about six times more frequently in women with unexplained infertility compared to the general public. The study authors noted, however, that previous studies were small so it's hard to know exactly how accurate those odds are. In addition, it also appeared that women with any type of infertility were more likely to be diagnosed with celiac disease.

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.
