While ICSI is a more invasive procedure, some have suggested it may help by reducing the risk of failed fertilisation. However, it's emerging that IVF is probably the preferred treatment, at least in the first cycle, in "unexplained" infertility. IVF allows for healthy competition between sperm, is less expensive, avoids trauma to the egg and may produce more embryos, with better pregnancy and live birth rates  
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 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.
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.
A review in 2013 came to the result that infants resulting from IVF (with or without ICSI) have a relative risk of birth defects of 1.32 (95% confidence interval 1.24–1.42) compared to naturally conceived infants.[48] In 2008, an analysis of the data of the National Birth Defects Study in the US found that certain birth defects were significantly more common in infants conceived through IVF, notably septal heart defects, cleft lip with or without cleft palate, esophageal atresia, and anorectal atresia; the mechanism of causality is unclear.[49] However, in a population-wide cohort study of 308,974 births (with 6,163 using assisted reproductive technology and following children from birth to age five) researchers found: "The increased risk of birth defects associated with IVF was no longer significant after adjustment for parental factors." [50] Parental factors included known independent risks for birth defects such as maternal age, smoking status, etc. Multivariate correction did not remove the significance of the association of birth defects and ICSI (corrected odds ratio 1.57), although the authors speculate that underlying male infertility factors (which would be associated with the use of ICSI) may contribute to this observation and were not able to correct for these confounders. The authors also found that a history of infertility elevated risk itself in the absence of any treatment (odds ratio 1.29), consistent with a Danish national registry study [51] and "implicates patient factors in this increased risk." The authors of the Danish national registry study speculate: "our results suggest that the reported increased prevalence of congenital malformations seen in singletons born after assisted reproductive technology is partly due to the underlying infertility or its determinants."
When I think back to that time, I recall an almost constant sense of grief. Every 28th day represented another failure, another loss. All around me my friends were having their second and then third babies. My son looked at his classmates with their siblings wistfully, he wished with every birthday candle for a brother or sister and one day he asked, "Can you play tig on your own?"
A risk of ovarian stimulation is the development of ovarian hyperstimulation syndrome, particularly if hCG is used for inducing final oocyte maturation. This results in swollen, painful ovaries. It occurs in 30% of patients. Mild cases can be treated with over the counter medications and cases can be resolved in the absence of pregnancy. In moderate cases, ovaries swell and fluid accumulated in the abdominal cavities and may have symptoms of heartburn, gas, nausea or loss of appetite. In severe cases patients have sudden excess abdominal pain, nausea, vomiting and will result in hospitalisation.

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.
A closer look at the data suggest that the benefit of letrozole over clomid depended on the BMI of the participants. For patients with a BMI of less than 30 kg/m2, the cumulative live birth rate was approximately 30% for each group. However, for patients with a BMI over 30 kg/m2, twice as many patients had a live birth in the letrozole group than the clomid group.
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.
When transferring more than one embryo, the risk of pregnancy and newborn complications also increases.1 Among IVF babies, twins are 12 times more likely than singletons to be delivered prematurely, 16 times more likely to be underweight and 5 times more likely to suffer from respiratory complications. Among IVF mothers, mothers of twins are 2.5 times more likely to have pre-eclampsia, over 8 times more likely to have premature preterm rupture of membranes and 4 times more likely to require a Caesarean section.

If you’re worried that you might be an infertile woman, don’t lose your hope. Be encouraged, and know that many women get pregnant even after being diagnosed with infertility. Know that there is a reason for what you’re going through. I trust God and I rely on His power, peace, and joy every day. I know there is a reason why we struggled with infertility – and perhaps the reason is so I could write about fertility and encourage couples like you to keep the faith.
A recent controversy in California focused on the question of whether physicians opposed to same-sex relationships should be required to perform IVF for a lesbian couple. Guadalupe T. Benitez, a lesbian medical assistant from San Diego, sued doctors Christine Brody and Douglas Fenton of the North Coast Women's Care Medical Group after Brody told her that she had "religious-based objections to treating her and homosexuals in general to help them conceive children by artificial insemination," and Fenton refused to authorise a refill of her prescription for the fertility drug Clomid on the same grounds.[111][112] The California Medical Association had initially sided with Brody and Fenton, but the case, North Coast Women's Care Medical Group v. Superior Court, was decided unanimously by the California State Supreme Court in favour of Benitez on 19 August 2008.[113][114]
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]
Treatment with Clomid tablets plus IUI improves fertility rates. For unexplained infertility, studies have shown that for women under 35, monthly success rates for Clomid plus insemination are about 10% per cycle. This pregnancy rate holds up for about 3 tries and the success rate is considerably lower after that. More about success rates with IUIs is on the insemination page and on the Clomid for unexplained infertility page. The insemination component boosts fertility more than the Clomid does - but success rates are higher when both are used together.

Give in to the grief. While you probably feel incredibly disappointed and sad about your infertility problems, you may feel guilty giving in to those emotions. Parents facing secondary infertility often feel they don’t have the “right” to feel sad about their struggles because they should be grateful for the child they already have. But if you want more children and are having trouble getting pregnant again, you are just as entitled as anyone else to feel depressed or angry. The last thing you need when you’re coping with secondary infertility is to let guilt weigh you down even more.

Infertility may have psychological effects. Partners may become more anxious to conceive, increasing sexual dysfunction.[17] Marital discord often develops, especially when they are under pressure to make medical decisions. Women trying to conceive often have depression rates similar to women who have heart disease or cancer.[18] Emotional stress and marital difficulties are greater in couples where the infertility lies with the man.[19]

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.

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.
Ovarian stimulation with hormonal medication is performed over a period of around 10-14 days. During this time, progress is monitored through ultrasound scans and blood tests. When enough oocytes (eggs) have developed in the ovaries, a final hormone injection triggers the maturing of the oocytes. Thirty-six hours later, egg retrieval is scheduled to take place in the fertility clinic.
Egg retrieval and sperm collection – Egg retrieval happens 35 hours after the trigger shot. It is done under light anesthesia and takes just 5-10 minutes. During retrieval, a tiny hollow needle is pierced through the vaginal wall towards an ovary. At this point, the fluid that contains the developed eggs is drained from the follicles and immediately taken to the IVF laboratory, where they will be fertilized and developed. Sperm is collected the same day as the procedure by ejaculation into a sterile specimen container, frozen ahead of time, via a donor, or through more advanced sperm retrieval procedures. Next, the sperm is washed, placed in a solution similar to the fallopian tubes, and used for fertilization.
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.

Wondering if it’s time to seek fertility help from a specialist? Your age can help clue you in to the answer. If you’re younger than 35, it’s perfectly normal for it to take six months to a year to conceive. If, after a year, you haven’t accomplished your conception goal, you’ll want to talk with your practitioner and/or get a referral to a fertility specialist. If you’re older than 35, experts recommend that you seek help from a fertility specialist after six months of regularly trying to conceive without birth control — and you may even want to go after three months. If you’re over 40, you’ll probably want to start off your quest for a second pregnancy with a fertility evaluation from your doctor. Ditto if your partner is over 40, since 35 to 40 percent of fertility problems can be traced back to the man, and a guy’s age affects the quality of his sperm.

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.
