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.
Initial blood work, cycle tracking and fertility analysis is done. To begin IVF, your doctor or fertility specialist will evaluate your hormone levels and menstrual cycle to determine what medications and plan of action may be needed. You may also undergo a transvaginal ultrasound to examine your ovaries and reproductive system, ensuring that they are healthy.

In cases where the man's sperm count is extremely low or there is poor motility (movement of the sperm), doctors may combine IVF with a procedure called intracytoplasmic sperm injection. In this procedure, a sperm is taken from semen -- or in some cases right from the testicles -- and inserted directly into the egg. Once a viable embryo is produced, it is transferred to the uterus using the usual IVF procedure.
Infertility is, in all its forms, a most private, hidden anguish. Nobody wants to discuss the finer points of their reproductive system in public. And the desire to have a child can, if thwarted, be so overwhelming that just a glimpse from a car window of someone with a BabyBjorn can be enough to produce such a flood of tears that you have to pull over. How can you possibly articulate that level of pain to the casual inquirer?

Cytoplasmic transfer is where the cytoplasm from a donor egg is injected into an egg with compromised mitochondria. The resulting egg is then fertilised with sperm and implanted in a womb, usually that of the woman who provided the recipient egg and nuclear DNA. Cytoplasmic transfer was created to aid women who experience infertility due to deficient or damaged mitochondria, contained within an egg's cytoplasm.
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.
Gathering the eggs. Your doctor gives you an anesthetic and inserts an ultrasound probe through your vagina to look at your ovaries and identify the follicles. A thin needle is then inserted through the vaginal wall to remove the eggs from the follicles. Eight to 15 eggs are usually retrieved. You may have some cramping and spotting for a few days afterward, but most women feel better in a day or two.

The cost of an IUI is almost certainly less on a per cycle basis, but because IVF has much higher success rates and IUI is a poor option for some, the higher per cycle cost of IVF can actually be more affordable in the long run – in terms of the cost to bring home a baby.  Because most successful IUIs happen in the first three or four-cycle, it eventually becomes very expensive to bring home a baby with an IUI.


Injectable medication cycle with IUI: If pregnancy doesn't result from ovulation induction with oral medications, the next step is to use injectable medications. These medications stimulate the ovaries to produce two to four eggs; when combined with IUI, you have an increased possibility of conception. Essentially, the sperm is given more targets to hit. You will come into the office for four to eight monitoring appointments to track egg development and cycle timing.
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]
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] 

Insemination – This is done as close to the day of ovulation as possible. During insemination, washed and concentrated sperm is injected into the top of your uterus through a small catheter inserted through the vagina and cervix. Once injected, the catheter is removed. You can expect the insemination to take just a few minutes. It is possible to experience mild cramping post-procedure. The sperm used in your IUI can usually be collected at the office performing the IUI (preferred if possible), frozen and shipped to the center, collected fresh at your home and shipped to our centers using our sperm shipping kits (not advised), or ordered and sent to our office from a donor agency. Fresh semen samples are prepared in our laboratory to obtain a concentration of active sperm.
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.
Only 30 percent of patients who receive 100 mg of Clomiphene a day will produce more than three follicles. Patients that produce less than than three follicles have about half the chance of getting pregnant than those that produce greater than three follicles. Patients that receive fertility medications but do not do an insemination have only half the success rates compared to those who do.
When weighing the options, the pros and cons of intrauterine insemination (IUI) and in vitro fertilization (IVF) will, of course, be explored fully in discussion with your physician. In general terms, you can expect IUI to be a simpler process, less invasive, and lower cost. Some fertility specialists recommend attempting one or more cycles of artificial insemination before moving to IVF but this does not apply to everyone. For example, for an older woman, to try artificial insemination first may take up valuable time and the recommendation could well be to move straight to IVF. But before you can compare the two treatments, you need to know what exactly you could expect from IVF.

IVF is a type of assisted reproductive technology used for infertility treatment and gestational surrogacy. A fertilised egg may be implanted into a surrogate's uterus, and the resulting child is genetically unrelated to the surrogate. Some countries have banned or otherwise regulate the availability of IVF treatment, giving rise to fertility tourism. Restrictions on the availability of IVF include costs and age, in order for a woman to carry a healthy pregnancy to term. IVF is generally not used until less invasive or expensive options have failed or been determined unlikely to work.
By 2017, many centers have adopted embryo cryopreservation as their primary IVF therapy, and perform few or no fresh embryo transfers. The two main reasons for this have been better endometrial receptivity when embryos are transferred in cycles without exposure to ovarian stimulation and also the ability to store the embryos while awaiting the results of pre-implantation genetic testing.
The Rand Consulting Group has estimated there to be 400,000 frozen embryos in the United States in 2006.[83] The advantage is that patients who fail to conceive may become pregnant using such embryos without having to go through a full IVF cycle. Or, if pregnancy occurred, they could return later for another pregnancy. Spare oocytes or embryos resulting from fertility treatments may be used for oocyte donation or embryo donation to another woman or couple, and embryos may be created, frozen and stored specifically for transfer and donation by using donor eggs and sperm. Also, oocyte cryopreservation can be used for women who are likely to lose their ovarian reserve due to undergoing chemotherapy.[84]
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?”
Availability of IVF in England is determined by Clinical commissioning groups. The National Institute for Health and Care Excellence recommends up to 3 cycles of treatment for women under 40 years old with minimal success conceiving after 2 years of unprotected sex. Cycles will not be continued for women who are older than 40 years old.[156] CCGs in Essex, Bedfordshire and Somerset have reduced funding to one cycle, or none, and it is expected that reductions will become more widespread. Funding may be available in "exceptional circumstances" – for example if a male partner has a transmittable infection or one partner is affected by cancer treatment. According to the campaign group Fertility Fairness at the end of 2014 every CCG in England was funding at least one cycle of IVF".[157] Prices paid by the NHS in England varied between under £3,000 to more than £6,000 in 2014/5.[158] In February 2013, the cost of implementing the NICE guidelines for IVF along with other treatments for infertility was projected to be £236,000 per year per 100,000 members of the population.[159]
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.
IVF using no drugs for ovarian hyperstimulation was the method for the conception of Louise Brown. This method can be successfully used when women want to avoid taking ovarian stimulating drugs with its associated side-effects. HFEA has estimated the live birth rate to be approximately 1.3% per IVF cycle using no hyperstimulation drugs for women aged between 40–42.[63]
Fertility is often something people do not consider until they are actively trying to start a family, or in many cases after they have started having trouble conceiving. What many don’t realize is that couples ages 29-33 with normal functioning reproductive systems only have a 20-25% chance of conceiving in any given month. Add in any number of infertility factors from either gender and those chances can decrease significantly.
Nowadays, there are several treatments (still in experimentation) related to stem cell therapy. It is a new opportunity, not only for partners with lack of gametes, but also for homosexuals and single people who want to have offspring. Theoretically, with this therapy, we can get artificial gametes in vitro. There are different studies for both women and men.[65]

A Cochrane review came to the result that endometrial injury performed in the month prior to ovarian induction appeared to increase both the live birth rate and clinical pregnancy rate in IVF compared with no endometrial injury. There was no evidence of a difference between the groups in miscarriage, multiple pregnancy or bleeding rates. Evidence suggested that endometrial injury on the day of oocyte retrieval was associated with a lower live birth or ongoing pregnancy rate.[30]

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.
First, you take medication that makes several of your eggs mature and ready for fertilization. Then the doctor takes the eggs out of your body and mixes them with sperm in a lab, to help the sperm fertilize the eggs. Then they put 1 or more fertilized eggs (embryos) directly into your uterus. Pregnancy happens if any of the embryos implant in the lining of your uterus.
With egg donation and IVF, women who are past their reproductive years, have infertile male partners, have idiopathic female-fertility issues, or have reached menopause can still become pregnant. Adriana Iliescu held the record as the oldest woman to give birth using IVF and a donor egg, when she gave birth in 2004 at the age of 66, a record passed in 2006. After the IVF treatment some couples are able to get pregnant without any fertility treatments.[3] In 2018 it was estimated that eight million children had been born worldwide using IVF and other assisted reproduction techniques.[4]
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.
In 2006, Canadian clinics reported an average pregnancy rate of 35%.[11] A French study estimated that 66% of patients starting IVF treatment finally succeed in having a child (40% during the IVF treatment at the centre and 26% after IVF discontinuation). Achievement of having a child after IVF discontinuation was mainly due to adoption (46%) or spontaneous pregnancy (42%).[14]

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]
As with any medical procedure, there are some risks to keep in mind. When choosing between IUI and IVF, the risk is certainly something to consider. The chances of experiencing either a miscarriage or multiples are concerns many have when deciding to undergo fertility treatments. So let’s take a look at the odds of either of these things occurring, plus a few other risks to be aware of.
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
A genetic disorder. If you or your partner is at risk of passing on a genetic disorder to your child, you may be candidates for preimplantation genetic testing — a procedure that involves IVF. After the eggs are harvested and fertilized, they're screened for certain genetic problems, although not all genetic problems can be found. Embryos that don't contain identified problems can be transferred to the uterus.
The eggs are then fertilized with sperm that has been optimized in the laboratory so that sperm with poor morphology or motility are discarded and the healthiest remain. Fertilization usually takes place through Intracytoplasmic Sperm Injection (ICSI). In this high-precision technique, the best single sperm are selected and individually microinjected into each egg.
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.

The Clearblue Fertility Monitor is for couples who are trying to get pregnant and want to track ovulation. It has a touch screen monitor that is easy to use, stores information that you can share with your doctor. It can also help you detect the most common signs of infertility by showing you what your fertile days are. If you have no fertile days, then you may be dealing with female infertility.
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.
