Couples experiencing infertility have a range of treatment options. Women can take fertility drugs to stimulate ovulation, or undergo certain surgeries and procedures, like intrauterine insemination, which carefully places healthy sperm in the uterus right before an egg is released to increase the chances of fertilization. Men can also take fertility medication or undergo surgery to increase the chances of conception.

The likelihood of a diagnosis of unexplained infertility is increased substantially in women 35 and over - and greatly increased in women over 38. The reason for this is that there are more likely to be egg quantity and quality problems as women age. Since we do not have a "standard category" called egg factor infertility, these couples sometimes get lumped in to the "unexplained" infertility category.

The diagnosis is one of exclusion — that is, one which is made only after all the existing tests have been performed and their results found to be normal. This is why the frequency of this diagnosis will depend upon how many tests are done by the clinic — the fewer the tests, the more frequent this diagnosis. And the better the tests, the more likely you are getting a diagnosis instead of being told it's "unexplained."
We know this is a touchy subject, but unfortunately, there’s no way around it. Science says that age does play a role in fertility. This 2018 study correlated age as a statistically significant factor in secondary infertility compared to primary infertility. In the study, the average age of couples was higher among those experiencing secondary infertility.

If both partners are young and healthy and have been trying to conceive for one year without success, a visit to a physician or women's health nurse practitioner (WHNP) could help to highlight potential medical problems earlier rather than later. The doctor or WHNP may also be able to suggest lifestyle changes to increase the chances of conceiving.[62]


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.
Unfortunately, a couple cannot look at the TMC from a semen analysis and know precisely where they fit into this rubrik. That is because the TMCs recorded above were measured after the man already had his sperm washed for IUI. A sperm wash can lower TMCs by roughly 30% and a credible rule of thumb for a general estimate would be to take the “pre-wash” TMC from a semen analysis, subtract a third, then presume that will be the “post-wash” TMC and apply it to the above charts.

The Fallopian tubes are the site for fertilization before the embryo makes its way to the uterine cavity for implantation. If the Fallopian tubes are damaged, fertilization may not occur. If one Fallopian tube is blocked, it may be due to inherent disease involving both Fallopian tubes; even if the other Fallopian tube is open, it may not be able to provide the appropriate nurturing environment for fertilization and early embryo growth to take place.
I had a wonderful experience at CHA Fertility Clinic and got pregnant on my first cycle.  My son will turn two this year and I immediately contacted them when we were thinking of having a second child.  The doctors and staff are so kind, informative, and helpful, and they really put my mind at ease.  We had looked at other fertility clinics … Read More
Secondary infertility is a secret club and one, I've discovered, with permanent membership. I was in a supermarket the other day and ahead of me in the cereal aisle was a woman with a boy of about nine and twin babies in the trolley. As I passed, she turned and looked at us. I saw her clocking my children and their age-gap and she saw I was doing the same with hers. We looked at each other for a moment; she smiled and I smiled back and then we walked on.

Hashimoto's thyroiditis or chronic lymphocytic thyroiditis, is an autoimmune disorder causing inflammation of the thyroid gland. Hashimoto's thyroiditis is a type of hypothyroidism, and is the most common cause of hypothyroidism in the US. Symptoms of Hashimoto's thyroiditis may include dry skin, fatigue, weight gain, feeling cold, excessive sleepiness, dry skin, dry coarse hair, difficulty swallowing, a lump in the front of the throat, muscle cramps, mood changes, vague aches and pains, problems concentrating, leg swelling, constipation, and depression. There is no cure for Hashimoto’s thyroiditis. Diet changes, natural supplements, vitamins, or other natural products will not treat Hashimoto’s thyroiditis. Treatment for the autoimmune disorder is with thyroid hormone replacement therapy, which will be necessary for the rest of the person’s life.

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.
In general, the cost of IVF is higher than for IUI, but IVF confers the highest pregnancy rates per cycle. It is impossible to put a precise figure on the two treatments for comparison as much will depend on your personal treatment program. You can see some ballpark figures on the website of the Society for Assisted Reproductive Technology. It also contains an overview of the differences between IUI and IVF.
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]
In 2008, a California physician transferred 12 embryos to a woman who gave birth to octuplets (Suleman octuplets). This led to accusations that a doctor is willing to endanger the health and even life of women in order to gain money. Robert Winston, professor of fertility studies at Imperial College London, had called the industry "corrupt" and "greedy" stating that "one of the major problems facing us in healthcare is that IVF has become a massive commercial industry," and that "what has happened, of course, is that money is corrupting this whole technology", and accused authorities of failing to protect couples from exploitation: "The regulatory authority has done a consistently bad job. It's not prevented the exploitation of women, it's not put out very good information to couples, it's not limited the number of unscientific treatments people have access to".[101] The IVF industry has been described as a market-driven construction of health, medicine and the human body.[102]
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.
Having no period means ovulation isn’t taking place at all, so a pregnancy can’t happen because no eggs is making itself eligible to be fertilized. Similarly, having irregular periods makes achieving pregnancy difficult, because it’s hard to time intercourse properly -- if sperm and egg aren’t at the same place at the same time, there is no chance of pregnancy.
Intrauterine insemination (IUI) is one of the simpler, “low-tech” treatments for infertility and the starting point for many individuals and couples who are having difficulty with conception on their own. Patients who have been diagnosed with unexplained infertility, mild male factor infertility, a cervical factor, or irregular or absent ovulation are often good candidates for IUI.
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]

If a couple has been actively trying for over a year, it may be time to consider seeing a specialist. One thing we hear time and time again from our Glow Fertility Program partner physicians is that they wish their patients would come in sooner. Seeing a specialist as soon as you suspect you may have a problem trying to conceive can save you both time and money.
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.
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.
