We don't know what causes most cases of secondary infertility, says Jamie Grifo, M.D., Ph.D., program director of the New York University Fertility Center, in New York City. "The majority of the time, though, it reflects the fact that you're older now, so it's simply more difficult to get pregnant." The reality is that for women, fertility peaks at age 25 and drops by half between ages 30 and 40. As we age, egg quality declines and we're more likely to develop fibroids and endometriosis, which contribute to infertility. Other factors such as adding extra weight, taking new meds, or having surgery since your last pregnancy can be an issue. It may also be that your partner's sperm quality or production is now poor.
Mild IVF is a method where a small dose of ovarian stimulating drugs are used for a short duration during a woman's natural cycle aimed at producing 2–7 eggs and creating healthy embryos. This method appears to be an advance in the field to reduce complications and side-effects for women and it is aimed at quality, and not quantity of eggs and embryos. One study comparing a mild treatment (mild ovarian stimulation with GnRH antagonist co-treatment combined with single embryo transfer) to a standard treatment (stimulation with a GnRH agonist long-protocol and transfer of two embryos) came to the result that the proportions of cumulative pregnancies that resulted in term live birth after 1 year were 43.4% with mild treatment and 44.7% with standard treatment. Mild IVF can be cheaper than conventional IVF and with a significantly reduced risk of multiple gestation and OHSS.
IUI is a procedure during which processed and concentrated motile sperm are inserted directly into a woman’s uterus. This procedure is timed according to a woman’s ovulation, and may be performed one to two times in the days immediately following the detection of ovulation. After ovulation a woman’s egg is picked up by the fallopian tube and waits there for the sperm. Since the IUI procedure deposits higher concentrations of good quality sperm close to where the egg is waiting, the chances that the egg and sperm will find one another are increased.
Though there are some risk with older women pregnancies, there are some benefits associated with caesareans. A study has shown that births over 40 have a lower rate of birth trauma due to increased delivery by caesarean. Though caesarean is seen to benefit mothers over 40, there are still many risk factors to consider. Caesarean section may be a risk in the same way that gestational diabetes is.
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."
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.
One, two or three IVF treatments are government subsidised for women who are younger than 40 and have no children. The rules for how many treatments are subsidised, and the upper age limit for the women, vary between different county councils. Single women are treated, and embryo adoption is allowed. There are also private clinics that offer the treatment for a fee.
Federal regulations in the United States include screening requirements and restrictions on donations, but generally do not affect sexually intimate partners. However, doctors may be required to provide treatments due to nondiscrimination laws, as for example in California. The US state of Tennessee proposed a bill in 2009 that would have defined donor IVF as adoption. During the same session another bill proposed barring adoption from any unmarried and cohabitating couple, and activist groups stated that passing the first bill would effectively stop unmarried people from using IVF. Neither of these bills passed.
The best study in the field enrolled 750 women to receive clomid or letrozole, followed them for 5 courses of therapy and revealed that the group receiving letrozole had higher live birth rates and fewer multiple gestations. The data is of exceptional quality, and there’s no reason to believe the conclusion doesn’t also apply to the choice of drugs if these patients proceeded on to IUI.
Within the Orthodox Jewish community the concept is debated as there is little precedent in traditional Jewish legal textual sources. Regarding laws of sexuality, religious challenges include masturbation (which may be regarded as "seed wasting"), laws related to sexual activity and menstruation (niddah) and the specific laws regarding intercourse. An additional major issue is that of establishing paternity and lineage. For a baby conceived naturally, the father's identity is determined by a legal presumption (chazakah) of legitimacy: rov bi'ot achar ha'baal – a woman's sexual relations are assumed to be with her husband. Regarding an IVF child, this assumption does not exist and as such Rabbi Eliezer Waldenberg (among others) requires an outside supervisor to positively identify the father. Reform Judaism has generally approved IVF.
A woman's age is a major factor in the success of IVF for any couple. For instance, a woman who is under age 35 and undergoes IVF has a 39.6% chance of having a baby, while a woman over age 40 has an 11.5% chance. However, the CDC recently found that the success rate is increasing in every age group as the techniques are refined and doctors become more experienced.
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.
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
Along with being physically demanding, fertility treatments can also spark a roller-coaster of emotions each month, including hope, anger, disappointment, sadness, and guilt. Just the sight of a pregnant woman can evoke strong negative and stressful feelings. During this time, those struggling with infertility may pull away from friends and family who remind them of their difficulty with reproduction; some of their closest relationships may suffer.
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.
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.
With each year that passes, your chances of conceiving decrease significantly, says Julie Tan, M.D., a gynecologist at the Cleveland Clinic Center for Reproductive Medicine, in Ohio. Sometimes even doctors downplay infertility, she notes. Most experts recommend seeing your doc after a year of unsuccessful unprotected sex if you're under age 35 and after six months if you're over 35. But if you're worried sooner, speak up. "If it's been three months and you're concerned, it's not too early to get evaluated, even though it may be premature to treat," explains Dr. Grifo. "Waiting a year to find out there's an issue with sperm count or egg supply can lead to a lot of heartache." You can start with your primary-care doc or ob-gyn but if you're not pregnant after a few months or feel your doctor isn't taking the situation seriously, see a fertility specialist.
Women are not always the source of a couple's infertility—in approximately one-third of cases, men may have difficulty with conception. In another third of cases, men are a contributing factor, along with female infertility and other problems. Men should be evaluated by a physician if there is a family history of infertility, if they have undergone cancer treatment, if they have small testicles, a swollen scrotum, or a low sperm count, or if they have any other testicular, prostate, or sexual problems.
Embryos are transferred to the uterus. Embryos that have developed from the fertilization process will be placed in the uterus, normally 3 to 5 days after retrieval, so that they can embed. If this process is successful, pregnancy will occur and IVF is considered a success. If it’s not, you may use a frozen embryo that you have saved from a previous round of IVF to try again.
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.
Preimplantation genetic screening (PGS) or preimplantation genetic diagnosis (PGD) has been suggested to be able to be used in IVF to select an embryo that appears to have the greatest chances for successful pregnancy. However, a systematic review and meta-analysis of existing randomised controlled trials came to the result that there is no evidence of a beneficial effect of PGS with cleavage-stage biopsy as measured by live birth rate. On the contrary, for women of advanced maternal age, PGS with cleavage-stage biopsy significantly lowers the live birth rate. Technical drawbacks, such as the invasiveness of the biopsy, and non-representative samples because of mosaicism are the major underlying factors for inefficacy of PGS.
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. Co-treatment with GnRH agonists appears to improve outcomes, by a live birth rate RD of +16% (95% confidence interval +10 to +22%). On the other hand, growth hormone or aspirin as adjunctive medication in IVF have no evidence of overall benefit.
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.
Infertility can have a profound impact on one’s mental health. When men and women find out that they can’t conceive, they may experience the same painful emotions as anyone coping with grief or profound loss. Common reactions include shock, frustration, grief, anger, decreased self-esteem, anxiety, and depression, but feelings about infertility can vary greatly depending on the source of the problems. Men, in particular, find it far easier to deal with a partner’s infertility than with their own.
