Secondary infertility can be traced to either partner or both partners. About one-third of cases originate in women and about one-third originate in men. In the remaining one-third, the cause is due to a combination of factors or isn’t known. Increased age, complications from a prior pregnancy or surgery, increased weight, medications, sexually transmitted diseases, impaired sperm production, alcohol abuse, and smoking are all examples of secondary infertility in women and men.
IVF is complicated and, while we wish we could say that it's possible to absorb all the details during the 5 - 30 minute visits with your doctor, that's really not the case. This comprehensive guide to IVF boils down every major issue you'll encounter -- a high level overview of the IVF process, a deeper dive into the IVF process, IVF success rates and how they differ depending on diagnosis and age, the medication protocols that can be used during IVF, the choice of inseminating eggs either using ICSI fertilization or conventional insemination, the pros and cons of growing embryos to Day 3 cleavage stage or Day 5 blastocyst stage, the decisions around genetic screening of embryos, deciding which embryo to transfer, deciding how many embryos to transfer at once, the ways the IVF laboratory can impact your odds of success and the things you need to know up front to avoid going to the wrong lab for you, the risks of IVF, and the costs of IVF. We're always sure to provide details about how data might be different depending on different unique types of patients -- because in the world of fertility, it's really not one-size-fits-all. We truly believe this guide is the foundation every fertility patient should start with when they're navigating the world of treatments.
In males with hepatitis B, The Practice Committee of the American Society for Reproductive Medicine advises that sperm washing is not necessary in IVF to prevent transmission, unless the female partner has not been effectively vaccinated.[37][38] In females with hepatitis B, the risk of vertical transmission during IVF is no different from the risk in spontaneous conception.[38] However, there is not enough evidence to say that ICSI procedures are safe in females with hepatitis B in regard to vertical transmission to the offspring.[38]
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.

In the UK, previous NICE guidelines defined infertility as failure to conceive after regular unprotected sexual intercourse for two years in the absence of known reproductive pathology.[11] Updated NICE guidelines do not include a specific definition, but recommend that "A woman of reproductive age who has not conceived after 1 year of unprotected vaginal sexual intercourse, in the absence of any known cause of infertility, should be offered further clinical assessment and investigation along with her partner, with earlier referral to a specialist if the woman is over 36 years of age."[12]
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.

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)
Cancer. Although some early studies suggested there may be a link between certain medications used to stimulate egg growth and the development of a specific type of ovarian tumor, more-recent studies do not support these findings. There does not appear to be a significantly increased risk of breast, endometrial, cervical or ovarian cancer after IVF. 

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.
Since each couple is unique in the cause of infertility, the answer as to whether ICSI or conventional IVF is more beneficial could vary. A retrospective cohort study published in 2015 is the most comprehensive study so far comparing the two strategies with different infertility factors, which will be the focus here1. A few other smaller-scale studies will also be discussed.
That’s about the time frame women between the ages of 35 and 40 should give themselves, before discussing fertility concerns with their doctor. For women under 35, experts recommend trying for about a year—really trying, as in unprotected, well-timed intercourse—before having any testing or treatment; women over 40 may want to consult an obstetrician/gynecologist right away. See your doctor sooner than later if you’ve suffered multiple miscarriages, have a history of pelvic inflammatory disease (a serious complication of some STDs), or experience any other symptoms of infertility. Meanwhile, learn these infertility myths you don’t have to worry about.
With each year that passes, your chances of conceiving decrease significantly, says Julie Tan, M.D., a gynecologist at the Cleveland Clinic Center for Reproductive Medicine, in Ohio. Sometimes even doctors downplay infertility, she notes. Most experts recommend seeing your doc after a year of unsuccessful unprotected sex if you're under age 35 and after six months if you're over 35. But if you're worried sooner, speak up. "If it's been three months and you're concerned, it's not too early to get evaluated, even though it may be premature to treat," explains Dr. Grifo. "Waiting a year to find out there's an issue with sperm count or egg supply can lead to a lot of heartache." You can start with your primary-care doc or ob-gyn but if you're not pregnant after a few months or feel your doctor isn't taking the situation seriously, see a fertility specialist.

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.
Success rates for IVF depend on a number of factors, including the reason for infertility, where you're having the procedure done, and your age. The CDC compiles national statistics for all assisted reproductive technology (ART) procedures performed in the U.S., including IVF, GIFT, and ZIFT, although IVF is by far the most common; it accounts for 99% of the procedures. The most recent report from 2016 found:

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…


iui versus ivf : While approaching an IVF specialist in order to conceive baby, infertile couples come across several options through which they can achieve their goal. These include IUI, IVF and surrogacy. People wishing to carry their child and avoid using a surrogate get to choose between IVF and IUI. But here comes the big dilemma which procedure to choose?
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.
Using the information that you enter below, this tool allows you to estimate your chance of having a live birth using in vitro fertilization (IVF)—the most common type of Assisted Reproductive Technology (ART). This information is calculated based on the experiences of women and couples with similar characteristics. The estimates are based on the data we have available and may not be representative of your specific experience. Additionally, this IVF success estimator does not provide medical advice, diagnosis, or treatment. Please speak with your doctor about your specific treatment plan and potential for success.

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.

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.


For women, problems with fertilisation arise mainly from either structural problems in the Fallopian tube or uterus or problems releasing eggs. Infertility may be caused by blockage of the Fallopian tube due to malformations, infections such as chlamydia or scar tissue. For example, endometriosis can cause infertility with the growth of endometrial tissue in the Fallopian tubes or around the ovaries. Endometriosis is usually more common in women in their mid-twenties and older, especially when postponed childbirth has taken place.[55]
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.
Obesity: The obesity epidemic has recently become is a serious issue, particularly in industrialized nations. The rising number of obese individuals may be due in part to an energy-rich diet as well as insufficient physical exercise.  In addition to other potential health risks, obesity can have a significant impact on male and female fertility. BMI (body mass index) may be a significant factor in fertility, as an increase in BMI in the male by as little as three units can be associated with infertility. Several studies have demonstrated that an increase in BMI is correlated with a decrease in sperm concentration, a decrease in motility and an increase DNA damage in sperm. A relationship also exists between obesity and erectile dysfunction (ED). ED may be the consequence of the conversion of androgens to estradiol. The enzyme aromatase is responsible for this conversion, and is found primarily in adipose tissue. As the amount of adipose tissue increases, there is more aromatase available to convert androgens, and serum estradiol levels increase. Other hormones including inhibin B and leptin, may also be affected by obesity. Inhibin B levels have been reported to decrease with increasing weight, which results in decreased Sertoli cells and sperm production. Leptin is a hormone associated with numerous effects including appetite control, inflammation, and decreased insulin secretion, according to many studies. Obese women have a higher rate of recurrent, early miscarriage compared to non-obese women.

By 2012 Costa Rica was the only country in the world with a complete ban on IVF technology, it having been ruled unconstitutional by the nation's Supreme Court because it "violated life."[177] Costa Rica had been the only country in the western hemisphere that forbade IVF. A law project sent reluctantly by the government of President Laura Chinchilla was rejected by parliament. President Chinchilla has not publicly stated her position on the question of IVF. However, given the massive influence of the Catholic Church in her government any change in the status quo seems very unlikely.[178][179] In spite of Costa Rican government and strong religious opposition, the IVF ban has been struck down by the Inter-American Court of Human Rights in a decision of 20 December 2012.[180] The court said that a long-standing Costa Rican guarantee of protection for every human embryo violated the reproductive freedom of infertile couples because it prohibited them from using IVF, which often involves the disposal of embryos not implanted in a patient's uterus.[181] On 10 September 2015, President Luis Guillermo Solís signed a decree legalising in-vitro fertilisation. The decree was added to the country's official gazette on 11 September. Opponents of the practice have since filed a lawsuit before the country's Constitutional Court.[182]
Assisted hatching. About five to six days after fertilization, an embryo "hatches" from its surrounding membrane (zona pellucida), allowing it to implant into the lining of the uterus. If you're an older woman, or if you have had multiple failed IVF attempts, your doctor might recommend assisted hatching — a technique in which a hole is made in the zona pellucida just before transfer to help the embryo hatch and implant. Assisted hatching is also useful for eggs or embryos that have been previously frozen as the process can harden the zona pellucida.

Studies show that sperm count and sperm movement decrease as men age, as does sexual function. But there isn't a cutoff age that makes a man too old to father a child. One study found that it took men age 45 or older longer to get a woman pregnant once the couple started trying. If your partner is older, you may want to talk to your doctor about ways to boost your chances.
3. Painful Periods: We’re not talking about normal cramping here. But, severe pain that stops you in your tracks and even causes nausea or vomiting. Alone this may not be a sign of infertility, but combined with other symptoms like pain during intercourse, blood in the urine or during bowel movements, or irregular periods, can be signs of endometriosis–a condition that accounts for 20-40% of female infertility cases.
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?”
IUI: An IUI can be done with no medications or a number of different medications to help develop and ovulate one or two eggs. Around day 14 of a woman’s cycle, the insemination takes place which deposits sperm inside the uterus. This greatly increases the number of sperm at the junction of the uterus and fallopian tubes, the distance they have to swim to meet the egg, and thus increases the chances of natural conception for many people.
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.

Women are born with about 1 million to 2 million eggs but release only 300 to 400 through ovulation during their lifetimes. Usually, you release just one each month. The egg travels along one of the two fallopian tubes that connect your ovaries to your uterus. If the timing is right, sperm may fertilize it on its way to the uterus. If fertilization doesn't happen within 24 hours of the egg leaving the ovary, the egg dissolves. Sperm can live for about 3 to 5 days, so knowing when you are ovulating can help you and your partner plan sex for when you're most likely to conceive.

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 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:

Problems with your periods or menstrual cycle is a sign of ovulation problems – and if you aren’t ovulating, you won’t get pregnant. Menstrual problems are the most obvious sign of infertility in women – but they don’t necessarily mean you’re infertile. Most women have some type of problem with their period: light flow, heavy flow, clotting, irregularity caused by stress or weight fluctuations, hormonal changes, etc.
