3 Yaş ile beraber over rezervi ve fertilite azalmakta
Aylık Fertilite oranı Relative rate Over the past few decades, postponement of childbearing has led to a decrease in family size and increased rates of age-related female subfertility. Age-related decreases in ovarian follicle numbers and a decay in oocyte quality dictate the occurrence of natural loss of fertility and, ultimately, menopause. While ART may help, it does not modify physiology. Fixed early in life: primordial germ cells arrive in the gonadal ridge by the seventh week of gestation. Total germ cell number peaks at 20 weeks of gestation! From a peak of 6-7 million, oocyte number declines to 350,000 by birth. By puberty, there are 200,000 follicles remaining in the ovary. Menopause sets in at an average age of 51 years, although the rate of the ovarian aging process is highly variable. Female age (y) Broekmans et al. Trends Endocrinol Metab. 2007;18:58.

Often the Ob/Gyn will do initial evaluations and perform first-line treatments. Depending on the findings, patients may need to be referred to an infertility specialist known as a reproductive endocrinologist. Practice Committee of the American Society for Reproductive Medicine.

There are a number of tests that can be performed to help diagnose the cause of a patient’s infertility and help determine the course of treatment. During the first exam, the patient’s medical history will be taken, a full physical will be performed, and hormone levels will be measured. Biochemical markers such as basal LH, FSH, E2, inhibin B, anti-Müllerian hormone (AMH), FSH:LH ratio, and midluteal progesterone concentrations can be used to determine the patient’s ovulatory status and ovarian reserves. Other tests are also used to verify ovulatory status, ovarian reserves, and other factors that may impact the patient’s ability to conceive and carry a pregnancy to full term. The next few slides will show some examples of other tests that may be performed. Bowen et al. Fertil Steril. 2007;88:390. Practice Committee of the American Society for Reproductive Medicine.

Genetik tarama Ideally, evaluation of the male partner should be conducted at the same time as the female partner to determine appropriate management of the couple as well as to spare the couple the distress of attempting ineffective therapies. During the first exam, the male partner’s reproductive medical history will be taken and a full physical will be performed with a semen analysis. If possible, 2 semen analyses should be conducted, separated by a period of 1 month. Semen analysis provides information on semen volume and sperm quality and quantity. Analysis of basal hormone concentrations may provide information on abnormal spermatogenesis. Hormonal abnormalities of the hypothalamic-pituitary-testicular axis are rare, but are a possible cause of male infertility. Testicular biopsy or examination and ultrasonography may reveal pathologies or obstructions. In addition, further specialized genetic and sperm analyses may be useful in a small number of patients.

The first one was published in 1980, with subsequent updates in 1987, 1992 and These manuals are used as a source of standard methodology for laboratories performing semen analyses worldwide. In 2010, the World Health Organization (WHO) has established new reference values for human semen characteristics which are markedly lower than those previously reported. At first glance, these new values seem to indicate that semen quality is declining worldwide. However, before making any assumption, it is important to understand how these values were obtained. *Strict (Tygerberg) criterion

Ovulatory failure or dysfunction can be treated with ovulation induction (OI); tubal factor infertility or endometriosis can be treated with controlled ovarian stimulation (COS) and IVF. Male subfertility can be treated with intrauterine insemination (IUI) with or without OI. Unexplained male or female infertility can be treated with IUI, COS with IVF, or ICSI. All conditions need to be considered on a case-by-case basis (eg, not all patients with endometriosis should be treated with IVF; if analysis indicates the patient has patent tubes, these patients may first try IUI).

Results in an alteration in pulsatile GnRH secretion Leads to increases in gonadotropin secretion and follicular development CC is widely used for ovulation induction in women with PCOS and in couples with unexplained infertility. CC treatment successfully induces ovulation in about 80% of properly selected candidates. The key is “properly selected candidates.” Successful ovulation does not necessarily translate into a pregnancy. Pregnancy rates are much lower (30%-40% per cycle). 40%-45% of couples can become pregnant within 6 cycles. Failure to conceive after successfully induced ovulation is indication for further evaluation.

21 CC: Riskler CC Tedavi 6 siklus ile sınırlandırılmalı.

Çoğul gebelik Tedavi 6 siklus ile sınırlandırılmalı. Kişisel özellikler ön plana alınarak daha kısa olabilir Yaş, evlilik süresi, bazal karekteristikler vb CC is generally well tolerated although some side effects limit efficacy and raise safety concerns. Short-term, reversible side effects include: hot flashes, mood swings, visual disturbances, breast tenderness, pelvic discomfort, and nausea. The antiestrogenic effects may negatively impact the uterine lining leading to lower pregnancy rates. Transvaginal ultrasound assessment of endometrial thickness before ovulation can indicate thin endometrium (<6 mm). This is a repetitive effect, so patients with a diagnosis of thin endometrium during their first cycle are not candidates for further CC treatment. Risk of multiple pregnancy is increased with CC. Risk of cancer is increased among women who were treated with CC. Uterine cancer risk increases with more than 6 cycles of CC treatment. Risk of ovarian cancer increases among women treated with CC for more than 12 cycles. Treatment should be limited to no more than 6 cycles. The chance of success declines greatly after multiple cycles. Because of the potential side effects associated with CC, all patients should be monitored to assess response to treatment. Without ultrasound monitoring, the number of CC cycles should be limited to 3 (or fewer), and early referral should be considered. Althuis et al. Am J Epidemiol. 2005;161:607. Case.

Today, IVF is used to treat many causes of infertility, such as endometriosis and male factor, or when a couple’s infertility is unexplained. The basic steps in an IVF treatment cycle are COS, egg retrieval, insemination, fertilization, embryo culture, and embryo transfer. The medical risks of ART depend upon each specific step of the procedure and include: ovarian hyperstimulation syndrome (OHSS), complications associated with egg retrieval, ectopic pregnancy, and miscarriage. OHSS is usually not serious and resolves with outpatient management, although 1%-2% of cases are severe and require hospitalization. OHSS is dose-dependent and is avoided by careful titration. Some may view the increased probability of multiple births as a risk associated with IVF. This procedure is also costly and may result in significant psychologic distress for couples.

39 KOH: Gonadotropin Tedavisi
Amaç, daha fazla sayıda oosit elde etmek olduğundan daha yüksek dozlarda gonadotropin kullanılmakta (KOH: IU FSH; OI: IU FSH) Endojen hormonlarla etkileşimi önlemek için GnRH analog (agonist/ antagonist) Takiben oosit toplama, ICSI ve ET COS COS is used in protocols involving IVF to create multiple oocytes for eventual insemination and implantation. In order to initiate and sustain the growth and development of multiple follicles (rather than to support a single ovulation), higher doses of gonadotropins are required. COS requires higher doses of gonadotropins than OI ( IU of FSH vs IU for OI). COS also requires cotreatment with a GnRH analog to prevent interference of COS by endogenous hormones. hCG Borini and Dal Prato. Reprod Biomed Online. 2005;11:283.

Day 2 or 3 of menses Embryo Transfer Day 6 of FSH GnRH antagonist Cycle day 21-24 rFSH/hMG IVF or ICSI Luteal phase support There are 2 types of GnRH analog: GnRH agonists bind to GnRH receptors on the anterior pituitary and elicit the release of FSH and LH, which initially cause a flare response then a downregulation of the endogenous GnRH, FSH, and LH. GnRH antagonists bind to GnRH receptors and do not elicit a release of hormones, but instead cause an almost immediate downregulation of endogenous hormones. This diagram illustrates a treatment regimen with GnRH antagonists and a “long protocol” with a GnRH agonist in patients undergoing COS with recombinant FSH. In the antagonist protocol, gonadotropins are started on day 2 or 3 of the cycle, then the antagonist is started on day 6 and continues until the day of hCG administration. In the “long agonist” protocol, the agonist is started on day 21 to 24 of the previous cycle and continues through the day of hCG administration with gonadotropins started on day 2 or 3 of the treatment cycle. After hCG, the oocytes are retrieved, and fertilized in the laboratory using either IVF or ICSI, and then the embryos are transferred back into the patient. In most cases, luteal phase progesterone support is given. GnRH agonist rFSH/hMG Down regulation

43 An RCT to compare treatment initiated with 2 cycles of COH/IUI to immediate IVF in older women with unexplained infertility demonstrated superior pregnancy rates with fewer treatment cycles in the immediate IVF group Objective—To determine optimal infertility therapy in women at the end of their reproductive potential. Design—Randomized clinical trial. Setting—Academic medical centers and private infertility center in a state with mandated insurance coverage. Patients—Couples with ≥ 6 months of unexplained infertility; female partner aged 38–42. Interventions—Randomized to treatment with 2 cycles of clomiphene citrate (CC) and intrauterine insemination (IUI), follicle stimulating hormone (FSH)/IUI, or immediate IVF, followed by IVF if not pregnant. Main Outcome Measures—Proportion with a clinically recognized pregnancy, number of treatment cycles, and time to conception after 2 treatment cycles and at the end of treatment. Results—154 couples were randomized to receive CC/IUI (N=51), FSH/IUI (N=52), or immediate IVF (N=51); 140 (90.9%) couples initiated treatment. Cumulative clinical pregnancy rates per couple after the first 2 cycles of CC/IUI, FSH/IUI, or immediate IVF were 21.6%, 17.3%, and 49.0%, respectively. After all treatment, 71.4% (110/154) of couples conceived a clinically recognized pregnancy and 46.1% delivered at least one live-born baby. 84.2% of all live born infants resulting from treatment were achieved from IVF. There were 36% fewer treatment cycles in the IVF arm compared to either COH/IUI arm and couples conceived a pregnancy leading to a live birth after fewer treatment cycles. Conclusions—An RCT to compare treatment initiated with 2 cycles of COH/IUI to immediate IVF in older women with unexplained infertility demonstrated superior pregnancy rates with fewer treatment cycles in the immediate IVF group Goldman MB, Fertil Steril. 2014 43

52 Özet İnfertilite tedavi protokolleri ve başarı temel olarak over yaşı ile ilişkilidir. Bu her zaman gözönüne alınmalıdır. Ek bir faktör yok ise 35 yaşından önce bir yıllık infertilite öyküsü 35 yaşından sonra ise 6 aylık infertilite öyküsü var ise değerlendirmeye alınmalıdır. Temelde nedene yönelik tedavi planlanmalı WHO grup I de OI ilk seçenek Gonadotropin FSH +LH WHO grup II ilk seçenek CC IUI ın yeri tartışmalı, ancak ilk 2 deneme için geçerliliğini koruyor. Açıklanamayan infertilitede özellikle ileri yaşlarda direkt IVF e geçilmesi daha mantıklı Tedavinin tamamen bireyselleştirilmesi gerekir. Zaman ve yaş kaybına dikkat !!!
