Abstract

Background: In vitro fertilization, a form of assisted reproductive technique, is the union of a woman’s egg and a man’s spermatozoid outside the body. A number of parameters known as ovarian reserve markers, such as serum Follicle Stimulating Hormone (FSH) concentration, Antral Follicle Count (AFC) and serum anti-Müllerian hormone (AMH) concentration are widely used to predict ovarian responses to gonadotrophin stimulation during in vitro fertilization treatment. To obtain satisfactory results, it is necessary to assess ovarian reserve before planning treatment.

Methods: This is a retrospective study to evaluate the role of AMH in the prediction of ovarian response following an ovarian stimulation protocol in the assisted reproductive technologies cycles. Follow- up of 100 patients admitted to the IVF center of Mount Lebanon Hospital through year 2012.

Results: Retrospective analysis of data collected from the clinic of the doctor and the IVF center showed a positive association between ovarian response in terms of total number of oocytes and anti-Müllerian hormone levels. Higher level of AMH was associated with increased risk of developing hyperstimulation ovarian syndrome in response to IVF drugs.

Conclusion: Serum AMH levels confirmed as a marker for ovarian reserve and ovarian response during IVF also for individualization of both the treatment strategy and the patient’s expectations with a superiority on the other parameters.

Introduction

Overview of infertility: definition, prevalence, causes and treatment options

Infertility is defined by the failure to achieve a pregnancy after 12 months of regular unprotected sexual intercourse, although the criteria for the duration vary between different countries.

Worldwide prevalence of infertility is estimated to be around 72.4 million couples and around 40 million of those seek medical care [1]. In the UK, 15% couples present with infertility with an annual incidence of 1.2 couples per 1000 general population [2]. The main causes of infertility are tubal disease, ovulatory disorders, male factor and poor ovarian reserve. In a third of couples the cause of failure to achieve pregnancy is not established which is known as unexplained infertility (NICE 2013). Effective treatment options include improving lifestyle factors, medical and/or surgical treatment of underlying pathology, induction of ovulation and Assisted Reproductive Technology (ART). Assisted Reproduction consists of intrauterine insemination (IUI) and in vitro fertilization (IVF) cycles with or without intracytoplasmic sperm injection (ICSI) as well as treatment involving donated gametes.

Overview of IVF

In vitro fertilization, a form of assisted reproductive technique, is the union of a woman’s egg and a man’s spermatozoid outside the body.

An IVF treatment cycle involves: a) pituitary down-regulation; b) controlled ovarian stimulation; c) oocyte recovery; c) in vitro fertilization of eggs with sperm; d) transfer of resulting embryo(s) back to uterus and e) luteal phase support. Prevention of premature surge of luteinizing hormone during controlled ovarian stimulation (COS) is achieved by pituitary down-regulation using either preparations of gonadotrophin releasing hormone agonist, which is widely known as “Agonist cycle” or gonadotrophin releasing hormone antagonist which is known “Antagonist cycle” (Figure 1 and 2). Controlled ovarian stimulation involves administration of gonadotrophins to encourage the development of supernumerary preovulatory follicles followed by administration of exogenous human chorionic gonadotropin (hCG) or recombinant luteinizing hormone (rLH) to assist in maturation of oocytes 34-36 hours prior to egg collection which is usually conducted with guidance of transvaginal ultrasound scanning. Subject to sperm parameters, the fertilization of oocytes is conducted by in vitro insemination or intracytoplasmic sperm injection. The resulting embryo(s) are cultured under strict laboratory conditions and undergo regular qualitative and quantitative assessments before transferring the best quality embryo(s) back into uterus, during their cleavage (Day 2 or Day 3) or blastocyst (Day 5 or Day 6) stage of development. In natural menstrual cycles, under the influence of HCG, progesterone secreted by the ovarian corpus luteum ensures proliferative changes in the endometrium providing the optimal environment for implantation of embryo(s). However, in IVF treatment cycles, owing to pituitary down regulation and lack of HCG, progesterone levels are not in sufficiently high concentration to ensure an adequate endometrial receptivity. Therefore, exogenous analogues of this hormone are administered following transfer of embryo(s). This is called “luteal phase support” which, in patients with viable pregnancy, usually lasts till 12th week of gestation, when the placenta starts producing progesterone in sufficient quantities [3].
