Those fearful of conceiving with multiples should strongly consider IVF and only transferring one embryo at a time. In these circumstances, just 1% of pregnancies lead to twins, and triplets are even more rare. Alternatively, 8 - 30% of medicated IUI pregnancies lead to twins. Finally, the least preferable circumstance is do to IVF with multiple embryo transfer, where in women under 38 years of age, 30% of pregnancies culminate in a multiple birth.
If a physician believes infertility is a concern, a number of tests will be administered. For women, these may include ovulation testing, ovarian reserve testing, hormone testing, and hysterosalpingography (X-rays of the fallopian tubes) or other imaging tests. Assessing male infertility involves semen analysis, which examines the number of sperm, as well as their motility and morphology (shape). Other tests for men may include hormonal and genetic testing, testicular biopsy, and additional imaging.
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.
Intracytoplasmic sperm injection (ICSI) is where a single sperm is injected directly into an egg. Its main usage as an expansion of IVF is to overcome male infertility problems, although it may also be used where eggs cannot easily be penetrated by sperm, and occasionally in conjunction with sperm donation. It can be used in teratozoospermia, since once the egg is fertilised abnormal sperm morphology does not appear to influence blastocyst development or blastocyst morphology.[86]
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.

When you face secondary infertility, you’re dealing not only with the typical ups and downs of TTC, but also with the additional emotional fallout that is unique to those having difficulty getting pregnant with baby number two. In addition to feeling disappointed and upset, you may also be feeling shock (“I got pregnant so easily the first time, there’s no way I could have infertility problems”), guilt (“I already have a child, so I should be happy”) and even isolation (“I can’t connect with the people facing primary infertility and I can’t connect with my friends who have multiple kids”). How do you reconcile these conflicting emotions — and how do you tackle them while trying to raise the child you already have?

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]
In humans, infertility is the inability to become pregnant after one year of intercourse without contraception involving a male and female partner.[2] There are many causes of infertility, including some that medical intervention can treat.[3] Estimates from 1997 suggest that worldwide about five percent of all heterosexual couples have an unresolved problem with infertility. Many more couples, however, experience involuntary childlessness for at least one year: estimates range from 12% to 28%.[4] Male infertility is responsible for 20–30% of infertility cases, while 20–35% are due to female infertility, and 25–40% are due to combined problems in both parts.[2][5] In 10–20% of cases, no cause is found.[5] The most common cause of female infertility is ovulatory problems, which generally manifest themselves by sparse or absent menstrual periods.[6] Male infertility is most commonly due to deficiencies in the semen, and semen quality is used as a surrogate measure of male fecundity.[7]
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.
Luteal support is the administration of medication, generally progesterone, progestins, hCG, or GnRH agonists, and often accompanied by estradiol, to increase the success rate of implantation and early embryogenesis, thereby complementing and/or supporting the function of the corpus luteum. A Cochrane review found that hCG or progesterone given during the luteal phase may be associated with higher rates of live birth or ongoing pregnancy, but that the evidence is not conclusive.[79] Co-treatment with GnRH agonists appears to improve outcomes,[79] by a live birth rate RD of +16% (95% confidence interval +10 to +22%).[80] On the other hand, growth hormone or aspirin as adjunctive medication in IVF have no evidence of overall benefit.[30]
