Twenty-eight days is the average length of a menstrual cycle, though anything between 21 and 35 days is considered normal. Fluctuating a little from month to month is one thing, but if your period is so irregular that you don’t even try to track it anymore, it could indicate a problem producing eggs, or ovulating. Ovulation disorders (meaning you ovulate infrequently or not at all) account for infertility in about 25 percent of infertile couples, according to the Mayo Clinic. One of the most common causes of female infertility is polycystic ovarian syndrome (PCOS)—a condition characterized by longer than normal stretches between periods, or even skipping cycles for months in a row. (Get the silent signs of PCOS here.) Irregular periods may also result from excessive physical or emotional stress, which can mess with the hormones responsible for stimulating ovulation each month; being too heavy or too thin, or gaining or losing a lot of weight quickly may also have the same effect. Talk to your doctor; he may be able to prescribe fertility drugs to help induce or stimulate ovulation.


The main cause of male infertility is low semen quality. In men who have the necessary reproductive organs to procreate, infertility can be caused by low sperm count due to endocrine problems, drugs, radiation, or infection. There may be testicular malformations, hormone imbalance, or blockage of the man's duct system. Although many of these can be treated through surgery or hormonal substitutions, some may be indefinite.[57] Infertility associated with viable, but immotile sperm may be caused by primary ciliary dyskinesia. The sperm must provide the zygote with DNA, centrioles, and activation factor for the embryo to develop. A defect in any of these sperm structures may result in infertility that will not be detected by semen analysis.[58] Antisperm antibodies cause immune infertility.[23][24] Cystic fibrosis can lead to infertility in men.
Your doctor will also monitor whether or not the treatment led to a multiple pregnancy. IVF has a higher risk of conceiving multiples, and a multiple pregnancy carries risks for both the mother and the babies. Risks of a multiple pregnancy include premature labor and delivery, maternal hemorrhage, C-section delivery, pregnancy induced high blood pressure, and gestational diabetes.
IVF is the most successful method of fertility treatment utilized today to help couples to conceive. The basic components of the IVF process include stimulation of the ovaries to produce multiple eggs at a time, removal of the eggs from the ovary (egg retrieval), fertilization of the eggs in the laboratory, and subsequent placement of the resulting embryos into the uterus (embryo transfer). The chance of pregnancy from IVF depends primarily on the age of the woman, the cause of infertility, and factors related to the quality of the IVF laboratory.
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.
Ovarian hyperstimulation also includes suppression of spontaneous ovulation, for which two main methods are available: Using a (usually longer) GnRH agonist protocol or a (usually shorter) GnRH antagonist protocol.[60] In a standard long GnRH agonist protocol the day when hyperstimulation treatment is started and the expected day of later oocyte retrieval can be chosen to conform to personal choice, while in a GnRH antagonist protocol it must be adapted to the spontaneous onset of the previous menstruation. On the other hand, the GnRH antagonist protocol has a lower risk of ovarian hyperstimulation syndrome (OHSS), which is a life-threatening complication.[60]
The number to be transferred depends on the number available, the age of the woman and other health and diagnostic factors. In countries such as Canada, the UK, Australia and New Zealand, a maximum of two embryos are transferred except in unusual circumstances. In the UK and according to HFEA regulations, a woman over 40 may have up to three embryos transferred, whereas in the US, there is no legal limit on the number of embryos which may be transferred, although medical associations have provided practice guidelines. Most clinics and country regulatory bodies seek to minimise the risk of multiple pregnancy, as it is not uncommon for multiple embryos to implant if multiple embryos are transferred. Embryos are transferred to the patient's uterus through a thin, plastic catheter, which goes through her vagina and cervix. Several embryos may be passed into the uterus to improve chances of implantation and pregnancy.

IVF has many steps, and it takes several months to complete the whole process. It sometimes works on the first try, but many people need more than 1 round of IVF to get pregnant. IVF definitely increases your chances of pregnancy if you’re having fertility problems, but there’s no guarantee — everyone’s body is different and IVF won’t work for everyone.


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.
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.
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.

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.


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.
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.
1. Changes to Your Menstrual Cycle: This may be an absence of your period, heavier than normal flow or irregular menstrual cycles may be signs of infertility. Consider tracking your menstrual cycle to help you identify patterns or changes early on. This will also be helpful in case you ever seek guidance from a physician, as he or she will inquire about your medical history.

Once the embryos are ready, you will return to the IVF facility so doctors can transfer one or more into your uterus. This procedure is quicker and easier than the retrieval of the egg. The doctor will insert a flexible tube called a catheter through your vagina and cervix and into your uterus, where the embryos will be deposited. To increase the chances of pregnancy, most IVF experts recommend transferring up to three embryos at a time. However, this means you could have a multiple pregnancy, which can increase the health risks for both you and the babies.
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.
According to the data collected for 2014, these are the IVF success rates nationally, when using non-donor eggs, per egg retrieval. (These are not per cycle. In other words, these are the odds of a live birth after one egg retrieval, which may mean conception with fresh eggs/embryos in the cycle of the egg retrieval ​or after a frozen embryo transfer cycle in the following months.) 
Problems with the uterus: There are many conditions related to the uterus that can cause secondary infertility. Scarring can occur during a dilation and curettage (D&C) or Cesarean delivery that can create adhesions inside the uterus that interfere with future pregnancies Fibroids or polyps are benign (non-cancer) growths inside the uterus that can impair pregnancy. A retained placenta can cause infection and uterine scarring.
Ovarian hyperstimulation syndrome (OHSS) occurs in 10% of women going through IVF treatment. For most women, symptoms will be mild, and they will recover easily. For a small percentage, OHSS can be more serious and may require hospitalization. Less than 1% of women going through egg retrieval will experience blood clots or kidney failure due to OHSS.
In vitro fertilization (IVF) is a treatment for infertility or genetic problems. If IVF is performed to treat infertility, you and your partner might be able to try less-invasive treatment options before attempting IVF, including fertility drugs to increase production of eggs or intrauterine insemination — a procedure in which sperm are placed directly in your uterus near the time of ovulation.
Life isn’t fair – there’s no doubt about it. That’s why it helps to have faith in God, to know He loves you and wants you to have the best possible life. My husband and I can’t have children, and it was the most disappointing discovery of my life. Trusting God when you can’t get pregnant is not easy – especially if you’ve been trying to conceive for months or even years.
Endometriosis implants are most commonly found on the ovaries, the Fallopian tubes, outer surfaces of the uterus or intestines, and on the surface lining of the pelvic cavity. They also can be found in the vagina, cervix, and bladder. Endometriosis may not produce any symptoms, but when it does the most common symptom is pelvic pain that worsens just prior to menstruation and improves at the end of the menstrual period. Other symptoms of endometriosis include pain during sex, pain with pelvic examinations, cramping or pain during bowel movements or urination, and infertility. Treatment of endometriosis can be with medication or surgery.
Stay positive. Search for success stories — there are so many out there. Look within your personal network or support groups to find other women who have similar experiences with infertility. Connect with them and share your stories. Learn what they have done, what doctors they have worked with, and what contributed to their successful pregnancies.
The live birth rate is the percentage of all IVF cycles that lead to a live birth. This rate does not include miscarriage or stillbirth; multiple-order births, such as twins and triplets, are counted as one pregnancy. A 2017 summary compiled by the Society for Assisted Reproductive Technology (SART) which reports the average IVF success rates in the United States per age group using non-donor eggs compiled the following data:[10]
For women, intake of antioxidants (such as N-acetyl-cysteine, melatonin, vitamin A, vitamin C, vitamin E, folic acid, myo-inositol, zinc or selenium) has not been associated with a significantly increased live birth rate or clinical pregnancy rate in IVF according to Cochrane reviews.[30] The review found that oral antioxidants given to men in couples with male factor or unexplained subfertility may improve live birth rates, but more evidence is needed.[30]

While many cases of infertility remain unexplained, there may be answers in the epigenome. Unlike one’s genetic code, the epigenome is dynamic and can be modified by environmental factors and lifestyle choices. Fertility in many cases is a state which changes throughout one’s life. Given the lack of clear genetic or physiological causes of unexplained infertility, the epigenome is thought to be altered in this subset of patients. As a result, looking into the epigenetic basis of infertility can help clinicians inform treatment.

No matter how many times you've been asked, "When will you have another baby?" the query still stings. Try coming up with a quick comeback—like 'We actually love having an only child'—and commit it to memory, says Dr. Davidson. Another heartbreaker: your child's pleas for a sibling. Try, "You're so wonderful we don't need anyone besides you." Or maybe admit, "We'd like nothing more than to make you a big brother. We hope it'll happen."


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.

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.
