    October 14th, Sadly, It looks as if you could be losing this pregnancy! When it comes to reproduction, humans are the poorest performers of all mammals. RPL is defined as two 2 or more failed pregnancies. Conversely, repeated losses RPL , with isolated exceptions where the cause is structural e. In fact, the vast majority of cases of RPL are attributable to non-chromosomal causes such as anatomical uterine abnormalities or Immunologic Implantation Dysfunction IID.

    Since most sporadic early pregnancy losses are induced by chromosomal factors and thus are non-repetitive, having had a single miscarriage the likelihood of a second one occurring is no greater than average. The reason for this is that the more miscarriages a woman has, the greater is the likelihood of this being due to a non-chromosomal repetitive cause such as IID.

    This is precisely why we strongly advocate that all miscarriage specimens be karyotyped. There is however one caveat to be taken into consideration. Weakness of the neck of the cervix rendering it able to act as an effective valve that retains the pregnancy i.

    So also are developmental congenital abnormalities of the uterus e. In some cases intrauterine growth retardation, premature separation of the placenta placental abruption , premature rupture of the membranes and premature labor can also causes of late pregnancy loss. Much progress has been made in understanding the mechanisms involved in RPL.

    There are two broad categories: 1. Problems involving the uterine environment in which a normal embryo is prohibited from properly implanting and developing. This most commonly results in occult RPL. A major cause of RPL. Genetic abnormalities are rare causes of RPL. These are referred to as unbalanced translocation and they result from part of one chromosome detaching and then fusing with another chromosome.

    Additionally, a number of studies suggest the existence of paternal sperm derived effect on human embryo quality and pregnancy outcome that are not reflected as a chromosomal abnormality. Damaged sperm DNA can have a negative impact on fetal development and present clinically as occult or early clinical miscarriage. Diagnosis of such activation requires highly specialized blood test for cytokine activity that can only be performed by a handful of reproductive immunology reference laboratories in the United States.

    Alloimmune IID, i. Autoimmune IID is often genetically transmitted. Reactionary secondary autoimmunity can occur in conjunction with any medical condition associated with widespread tissue damage. One such gynecologic condition is endometriosis. Alloimmune IID, on the other hand, usually starts off presenting as unexplained miscarriages often manifesting as RPL. RPL is more commonly the consequence of alloimmune rather than autoimmune implantation dysfunction.

    This having been said, it is important to note that autoimmune IID is readily amenable to reversal through timely, appropriately administered, selective immunotherapy, and alloimmune IID is not. It is much more difficult to treat successfully, even with the use of immunotherapy. This was because sporadic miscarriages are most commonly the result of embryo numerical chromosomal irregularities aneuploidy and thus not treatable. However, a consecutive series of miscarriages points to a repetitive cause that is non-chromosomal and is potentially remediable.

    Since RPL is most commonly due to a uterine pathology or immunologic causes that are potentially treatable, it follows that early chromosomal evaluation of products of conception could point to a potentially treatable situation. Thus I strongly recommend that such testing be done in most cases of miscarriage. Doing so will avoid a great deal of unnecessary heartache for many patients. Establishing the correct diagnosis is the first step toward determining effective treatment for couples with RPL.

    It results from a problem within the pregnancy itself or within the uterine environment where the pregnancy implants and grows. Treatment of Thin Uterine Lining: A thin uterine lining has been shown to correlate with compromised pregnancy outcome. Often this will be associated with reduced blood flow to the endometrium.

    Such decreased blood flow to the uterus can be improved through treatment with sildenafil and possibly aspirin. Sildenafil Viagra Therapy. Viagra has been used successfully to increase uterine blood flow. However, to be effective it must be administered starting as soon as the period stops up until the day of ovulation and it must be administered vaginally not orally. Viagra in the form of vaginal suppositories given in the dosage of 25 mg four times a day has been shown to increase uterine blood flow as well as thickness of the uterine lining.

    It should be remembered that most of these women had previously experienced repeated IVF failures. Use of Aspirin: This is an anti-prostaglandin that improves blood flow to the endometrium.

    It is administered at a dosage of 81 mg orally, daily from the beginning of the cycle until ovulation. In cases where selective immunotherapy is needed to treat an immunologic implantation dysfunction. The reason for IVF being a preferred approach in such cases is that in order to be effective, the immunotherapy needs to be initiated well before spontaneous or induced ovulation.

    Conversely, with IVF, the chance of a successful outcome in a single cycle of treatment is several times greater and, because of the attenuated and concentrated time period required for treatment, IVF is far safer and thus represents a more practicable alternative Since embryo aneuploidy is a common cause of miscarriage, the use of preimplantation genetic diagnosis PGD , with tests such as CGH, can provide a valuable diagnostic and therapeutic advantage in cases of RPL.

    Other non-immunologic factors such as an intractably thin uterine lining or severe uterine pathology might also warrant that last resort consideration be given to gestational surrogacy. Please also take the time to post any questions or comments with the full expectation that I will as always respond promptly.

    All consultations are followed by a detailed written report presenting my personal recommendations for treatment of what often constitute complex Reproductive Issues. Geoff Sher October 20th, Hi Dr. I have a history of infertility. After 6 years we started with IUI and fell pregnant immediately. We had a early loss. We went over to IVF and the first one was unsuccessful with no embryos to freeze.

    The second has been successful. We transferred 2 embabies and have 3 in the freezer now. This pregnancy my hcg was 6dp5dt- 54 12dp5dt is should have been doubling time 54 hrs. Should I be concerned that its not exactly doubling?

    Contact An early beta hCG test does predict your risk of miscarriage That first glimpse of two pink lines—can it be? But after a few moments of celebration, you descend back to earth. Will this pregnancy stick? You have entered a new, more hopeful limbo than the much bemoaned two-week wait.

    We all know that miscarriage is very common , especially early in pregnancy. And for most women, good info about viability does not come until the first ultrasound, usually performed at weeks. Undergoing fertility treatments is less fun than a hangover. Embryos produce hCG once they implant. During the first trimester, blood levels of HCG rises quickly.

    They usually double every 48 hours, until reaching a peak around 20 weeks. After this peak, they begin a slow decline. Predicting ongoing pregnancy with HCG The level of hCG in your blood predicts your chances of an ongoing pregnancy—which researchers usually define as one that lasts through the first weeks.

    The table below summarizes findings from several IVF-based studies which tracked pregnancy outcomes by hCG levels. Note: The numbers below only apply to singleton pregnancies. Twin pregnancies typically have much higher hCG levels, and therefore these thresholds may not apply. When comparing your test results, pay close attention to the post-retrieval or post-transfer date listed in the Day tested column. Some studies report by day from egg retrieval post retrieval. Others report from day after blastocyst or embryo transfer post transfer.

    HCG rises rapidly in early pregnancy, so whether a specific beta is a positive or negative signs depends on precisely when hCG was measured. The hCG threshold for likely viability rises with each day. Your pregnancy has a very high chance of continuing through the first trimester.

    Your first ultrasound will provide better information than your beta about your chances of a live birth. What if your hCG is below those in the above table? In other words, hCG was better at predicting a good outcome than it was at predicting a bad outcome. Because hCG levels vary a lot from pregnancy to pregnancy, there is no strict cutoff for determining viability. This nearly always indicates a failing pregnancy. It can also indicate an ectopic pregnancy—an pregnancy that has implanted somewhere other than the uterus.

    One final caveat: All of the above studies involved women undergoing IVF. We cannot say whether these numbers apply to women undergoing IUI or who conceived naturally. Special case: Frozen embryo transfers Some but not all studies find that HCG levels are lower and less predictive of miscarriage after frozen as opposed to fresh embryo transfers.

    Ready, set, go! The coach blows the whistle and all the kids fly off the starting blocks, except mine. The coach blows again, long and hard. Would I cheer my kids on? Would I feel proud of them for having a go? Would I still believe they can finish the race?

    Of course I would! I would never give up on them and go home. I just need to be a mum right now, to the little life or lives growing inside me. I am truly grateful for this strange and wonderful experience of being pregnant.

    Low Beta hCG: what happens when the result isn’t around 100 mIU/ml

    If we go through IVF again, I can remind myself what not to do. Transfer day: two 5-day blastocysts come home to mamma — the happiest day.
