Anger, sadness, and anxiety are common among parents struggling to expand their family. "Having a child already doesn't make going through infertility any easier," says Alice D. Domar, Ph.D., executive director of the Domar Center for Mind/Body Health, in Waltham, Massachusetts, and author of Conquering Infertility. Meeting with a mental-health professional or seeking out blogs and online groups for secondary infertility can help. The website of  the National Infertility Association, resolve.org, is a good place to start.
In order for pregnancy to happen, sperm has to meet the egg. This normally takes place at the end of the fallopian tube, and this is called fertilization. There are a number of obstacles that can prevent this from happening, and the process itself even in healthy young fertile women is very complex- hence the low pregnancy rate each month. Obstacles such as cycle timing, low sperm count, poor sperm motility, blocked fallopian tubes, or endometriosis must be overcome to achieve a pregnancy. Timing is often the most common obstacle to conception. What does it mean for you when common causes of infertility are ruled out and you’re told you have unexplained infertility? It should mean a time of hope.
In a bid to understand my chances of IVF success, I took a quick dive through the vast information available from these sources and came away thinking I had the information I needed. I skipped merrily along thinking things looked pretty promising after reading my chances of IVF working the first time was somewhere around the 40% mark. I naively thought that meant I had an 80% chance if I did two cycles, and that I’d definitely have a baby after three rounds at the most. Unfortunately as later reflection revealed, math and statistic just don’t work like this…
A lot goes into determining your odds of IVF success. No matter how small or big each factor is, you should try to optimize all of them for a happy outcome. Don’t forget, you can also use the success rate calculator for a personalized predication. It is also important to plan multiple full IVF cycles no matter what the first IVF cycle outcome is. 3 full IVF cycles are generally recommended to improve your cumulative success rates. About two thirds of patients will be successful after six or more cycles of IVF.
Dr. Ajay Murdia is a renowned Doctor whose research has been published in a well-known medical journal called "The Lancent" in the UK. With a vision to eradicate infertility from India, Dr. Ajay Murdia established Indira Infertility Clinic in the year 1988. Initially, the main focus of Indira Infertility Clinic was male infertility, although now it aims to provide advanced fertility center across India for both men and women.
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.

All pregnancies can be risky, but there are greater risk for women who are older and are over the age of 40. The older the women the riskier the pregnancy. As women get older, they are more likely to suffer from conditions such as gestational diabetes and pre-eclampsia. If older women do conceive over the age of 40, their offspring may be of lower birth weight, and more likely to requires intensive care. Because of this, the increased risk is a sufficient cause for concern. The high incidence of caesarean in older mothers is commonly regarded as a risk.

Intracytoplasmic sperm injection (ICSI): This procedure involves direct injection of a single sperm of the male partner into the eggs of the female for fertilization. Just like IVF procedure, in ICSI, the sperm and egg are collected from both the partners. The only difference is the fertilization process as in IVF the sperms and egg are mixed naturally, and in ICSI the sperms are injected into the egg using a needle.
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.
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.  

Take a look at your lifestyle. Have any of your habits changed since you conceived baby number one? For instance, is your diet still on track, or is there room for improvement? Getting your eating plan up to baby-making speed may help you close in faster on conception. Has your caffeine consumption gone up now that you’re a mom? That’s understandable, but too much caffeine isn’t great for fertility. Has your smoking habit returned? If yes, it’s time to kick butt, since smoking ages your eggs and decreases fertility. Are you getting way too little sleep? That may be likely, especially if your first child is keeping you up at night, but skimping on sleep can mess with your hormones — and possibly your fertility. If any new unhealthy habit has slipped into your lifestyle, now’s a great time to put the brakes on it. And it’s not just about your habits. Is your partner kicking back one too many beers each night? That could be affecting his sperm quality. Ditto for smoking or an unhealthy diet. If your partner’s lifestyle needs a little fine-tuning, make efforts to get his back on track, too.

However, those percentages are from studies in which all the women had laparoscopy surgery to investigate the pelvic cavity for pelvic scarring and endometriosis. Laparoscopy surgery is no longer done as part of the routine fertility workup. Therefore, we are not finding all of the causes of infertility that we used to - leaving many more couples in the unexplained category.
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.
Fertilization. An embryologist (a scientist who specializes in eggs, sperm, and embryos) will examine your eggs before combining them with your partner's sperm and incubating them overnight. Fertilization usually happens during this time, but eggs that aren't normal may not be fertilized. (If sperm quality is poor, or if fertilization was unsuccessful during previous IVF cycles, your doctor may recommend using a technique called intracytoplasmic sperm injection (ICSI). With ICSI, a single sperm is injected directly into each mature egg.)
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.

Although menopause is a natural barrier to further conception, IVF has allowed women to be pregnant in their fifties and sixties. Women whose uteruses have been appropriately prepared receive embryos that originated from an egg of an egg donor. Therefore, although these women do not have a genetic link with the child, they have a physical link through pregnancy and childbirth. In many cases the genetic father of the child is the woman's partner. Even after menopause the uterus is fully capable of carrying out a pregnancy.[109]


The AMIGOS study suggested that clomid provided the best balance of a high pregnancy rate with a reasonably low multiple rate among couples with unexplained infertility. However, the authors of the Huang study concluded that on balance letrozole was better. From our vantage point, given that clomid more commonly causes multiple eggs to be ovulated, it seems like the slightly better option between the two because the whole point of treatment in unexplained infertility patients is to increase the odds of delivery by increasing the number of eggs ovulated.


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.
This chart is US national average data on success rates per IVF cycle by female age for 2014. The dark blue line (triangles) shows pregnancy rates per cycle by age. The orange line (circles) shows live birth rates per cycle by age. The rate of singleton live births per cycle is shown by the light blue line. The difference between "pregnancy" rate and "live birth" rate is due to miscarriages.
All pregnancies can be risky, but there are greater risk for women who are older and are over the age of 40. The older the women the riskier the pregnancy. As women get older, they are more likely to suffer from conditions such as gestational diabetes and pre-eclampsia. If older women do conceive over the age of 40, their offspring may be of lower birth weight, and more likely to requires intensive care. Because of this, the increased risk is a sufficient cause for concern. The high incidence of caesarean in older mothers is commonly regarded as a risk.
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.
One, two or three IVF treatments are government subsidised for women who are younger than 40 and have no children. The rules for how many treatments are subsidised, and the upper age limit for the women, vary between different county councils.[154] Single women are treated, and embryo adoption is allowed. There are also private clinics that offer the treatment for a fee.[155]
Time. The factor of time cuts both ways when you are weighing up these two options. IUI is a much shorter process than IVF, so if your first cycle is successful, it could be the quickest route to bringing home a baby. However, because of the gap in success rates between the two treatments, some patients in their late 30s to early 40s may get pregnant faster by going directly to IVF rather than waiting until they have had several failed IUI cycles.

Amongst these two patient populations (which we’ll refer to now as PCOS), IUI with clomid and letrozole generally shows no improvement versus when these drugs are taken without IUI. When IUI is coupled with gonadotropins, success rates reach 14 - 26% per cycle, which is higher than almost any other patient class, but still pales in comparison to IVF. It’s also worth noting that PCOS patients who are taking gonadotropins have a very high risk of multiples.
Prior to the retrieval procedure, you will be given injections of a medication that ripens the developing eggs and starts the process of ovulation. Timing is important; the eggs must be retrieved just before they emerge from the follicles in the ovaries. If the eggs are taken out too early or too late, they won't develop normally. Your doctor may do blood tests or an ultrasound to be sure the eggs are at the right stage of development before retrieving them. The IVF facility will provide you with special instructions to follow the night before and the day of the procedure. Most women are given pain medication and the choice of being mildly sedated or going under full anesthesia.

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.


Psychological factors: Studies on infertile groups of men and women have produced contradictory findings of the importance of psychological factors in causing infertility. Emotional disturbances undoubtedly appear to have some significance. This is only reasonable if you realize that the whole hormonal cycle, with its delicate adjustments, is controlled from the brain. This is an area which needs further investigation.
The AMIGOS study suggested that clomid provided the best balance of a high pregnancy rate with a reasonably low multiple rate among couples with unexplained infertility. However, the authors of the Huang study concluded that on balance letrozole was better. From our vantage point, given that clomid more commonly causes multiple eggs to be ovulated, it seems like the slightly better option between the two because the whole point of treatment in unexplained infertility patients is to increase the odds of delivery by increasing the number of eggs ovulated.
West states that the "hardest thing about secondary fertility issues is that you want a sibling for your child." Fiona, who has a son of five and has been trying to conceive a second child for two years, says she can no longer look out of the window at her son playing in the garden. "It breaks my heart. He just looks so alone out there. All I want is a sibling for him but I don't think it's going to happen."
Risk of multiples. IUI with fertility medication carries a significant risk of multiple pregnancies, including higher-order multiples (triplets or more). A good clinic will carefully monitor your follicles to make sure that only a safe number are mature before the IUI, but they cannot entirely eliminate the risk. Recent advances in IVF (including blastocyst transfer) mean that most modern fertility clinics now transfer only one or two embryos per IVF cycle. As a result, the risk of multiple pregnancies for IVF patients is much lower than it used to be.
Nonmedicated cycle with IUI: Also known as natural cycle IUI, a non-medicated cycle with IUI is often used by single women or same-sex female couples who are not directly experiencing infertility, but rather a lack of sperm. This treatment involves tracking the development of the egg that is naturally recruited during a menstrual cycle and then introducing the donated sperm. You will come into the office for two to four monitoring appointments to track egg development and cycle timing.
Addressing lifestyle issues is not meant to be a quick fix, and typically does not lead to instant success. However, with unexplained infertility every little bit counts, so don’t fret or give up. Do not assume just because the cause of infertility is unexplained, it is untreatable or there is no pathway to parenthood. When a specific cause is not determined for women, and male infertility has also been ruled out, our fertility specialist may begin a course of treatment to improve the chances of conception and pregnancy. The speed with which interventions are offered depends on each individual’s own needs and desires as determined by age and other factors.
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.
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]
Low weight: Obesity is not the only way in which weight can impact fertility. Men who are underweight tend to have lower sperm concentrations than those who are at a normal BMI. For women, being underweight and having extremely low amounts of body fat are associated with ovarian dysfunction and infertility and they have a higher risk for preterm birth. Eating disorders such as anorexia nervosa are also associated with extremely low BMI. Although relatively uncommon, eating disorders can negatively affect menstruation, fertility, and maternal and fetal well-being.
I used to have a neighbour I would do almost anything to avoid. An elderly lady, she was given to jam-making, church-going and patrolling the local streets. If I saw her coming, I would dive back inside my front door or seize my son's hand and gallop to our car. I once twisted my ankle in an effort to escape her. Whenever she saw me she would utter the words, "If you don't get your skates on and give that child a brother or sister he's going to be a lonely only." Even now, it's hard to say what was more loathsome. Was it the boisterous intrusion of her tone, the inexcusability of the phrase "lonely only", or the idea of strapping on skates as a euphemism for – what exactly? Unprotected sex?

We don't know what causes most cases of secondary infertility, says Jamie Grifo, M.D., Ph.D., program director of the New York University Fertility Center, in New York City. "The majority of the time, though, it reflects the fact that you're older now, so it's simply more difficult to get pregnant." The reality is that for women, fertility peaks at age 25 and drops by half between ages 30 and 40. As we age, egg quality declines and we're more likely to develop fibroids and endometriosis, which contribute to infertility. Other factors such as adding extra weight, taking new meds, or having surgery since your last pregnancy can be an issue. It may also be that your partner's sperm quality or production is now poor.
A surge in LH triggers your ovaries to release an egg. The surge usually happens 36 hours before the egg is released. Ovulation kits check LH levels in your urine to help you pinpoint the day of ovulation. These kits, which you can buy at the drugstore, are convenient and highly accurate. You may want to test 1-2 days before you expect the surge so you can note the rise in LH.
