Controlled ovarian stimulation with subsequent multi-follicular development continues to be a keystone in ART. Evidence supports an individualized approach to ovarian stimulation, usually involving combinations of ovarian reserve tests, body mass index and age to tailor the exogenous gonadotropin dose, and potentially adjuvant treatment aiming for high safety and a shortening of time to live birth. While stimulation and trigger concepts have been developed successfully in normo- and hyperresponder patients, the poor responder patient remains difficult to manage...

The number of oocytes retrieved is a relevant intermediate outcome in women undergoing IVF/intracytoplasmic sperm injection (ICSI). This trial compared the efficiency of the selection of the FSH starting dose according to a nomogram based on multiple biomarkers (age, day 3 FSH, anti-Müllerian hormone) versus an age-based strategy. The primary outcome measure was the proportion of women with an optimal number of retrieved oocytes defined as 8-14. At their first IVF/ICSI cycle, 191 patients underwent a long gonadotrophin-releasing hormone agonist protocol and were randomized to receive a starting dose of recombinant (human) FSH, based on their age (150 IU if ≤35 years, 225 IU if >35 years) or based on the nomogram...

OBJECTIVE: Poor ovarian response to ovarian hyperstimulation is one of the biggest challenges in assisted reproduction technology. Although many stimulation protocols have been established to improve clinical outcomes in poor ovarian responders (PORs), which protocol is the most effective remains controversial. Luteal-phase ovarian stimulation (LPOS) has been used in normal ovarian responders with satisfactory outcomes. However, the efficacy of LPOS in PORs is unclear. This study aimed to compare the efficacy of LPOS and GnRH antagonist (GnRH-ant) in PORs...

Ovarian reserve markers have been documented to perform very well in the clinical practice. While this is widely recognized, still now there is no consensus on how to use new biomarkers in the clinical practice. This study was conducted among Italian IVF centres using the Delphi technique, a validated consensus-building process. Briefly three consecutive questionnaires were developed for clinicians in charge of IVF centres. In the first rounds, participants were asked to rate the importance of a list of statements regarding the categorization of ovarian response and the diagnostic role of biomarkers...

The aim of this study was to evaluate whether prolongation of the time interval between HCG administration and oocyte retrieval, from 36 h to 38 h, affects oocyte retrieval rate in women undergoing ovarian stimulation with gonadotrophins and GnRH antagonists for IVF. One hundred and fifty-six normo-ovulatory women were randomized to have oocyte retrieval performed 36 h (n = 78) or 38 h (n = 78) following HCG administration. Oocyte retrieval rate was defined as number of cumulus-oocyte-complex (COC) retrieved/follicle ≥ 11 mm present on day of HCG administration...

Ovarian hyperstimulation syndrome (OHSS) is one of the most serious, and potentially lethal, complications of controlled ovarian stimulation (COS). Induction of final oocyte maturation with a bolus of gonadotropin-releasing hormone (GnRH) agonist (GnRHa), instead of the criterion standard hCG, in patients undergoing ovarian stimulation significantly reduces the risk of OHSS and could be considered to be more physiologic. A bolus of GnRHa used in this context also acts as a luteolytic agent. From a clinical point of view, the most significant benefit of GnRHa trigger is its ability to induce quick and reversible luteolysis and thus reducing the risk of OHSS development...

Normogonadotropic anovulation, including polycystic ovary syndrome (PCOS), is one of the main causes of infertility. Recent meta-analysis and randomized controlled trial suggest the use of aromatase inhibitors (ie, letrozole) as effective drug and first-line treatment to restore fertility in these patients. The current manuscript will give a critical, provocative, and personal point of view on the topic.

A single bolus of human chorionic gonadotropin (hCG) at midcycle has been the gold standard for triggering final oocyte maturation and ovulation in assisted reproductive technology cycles. More recently, gonadotropin-releasing hormone (GnRH)-agonist (GnRH-a) triggering has been introduced. The GnRH-a trigger may allow a more physiologic surge of both luteinizing hormone (LH) and follicle-stimulating hormone, although whether the combined surge will result in improved oocyte and embryo quality remains to be seen...

PURPOSE: To evaluate the efficacy of minimal stimulation using discretely administered gonadotropin combined with clomiphene citrate (CC) or letrozole (LTZ) for intrauterine insemination (IUI) cycles. MATERIALS AND METHODS: Total 257 IUI cycles from 158 infertile couples were assessed. A CC dose of 100 mg/day (n=126 cycles) or a LTZ dose of 5 mg/day (n=131 cycles) was administered on days 3-5 of the menstrual cycle for 5 days. Each group received human menopausal gonadotropin at a dose of 150 IU by two or three alternative day: CC combined with alternate-day regimen for 2 or 3 days (CC+300, n=37; CC+450, n=89) and LTZ combined with alternate-day regimen for 2 or 3 days (LTZ+300, n=36; LTZ+450, n=95)...

Assisted reproductive technology is widely used to treat couples affected by infertility. Complications associated with assisted reproduction include venous thromboembolism, ovarian hyperstimulation syndrome, and recurrent implantation failure. It has also been proposed that thrombophilia may be associated with an increased likelihood of these events. Although data are limited, antithrombotic therapy is frequently used to enhance the likelihood of successful assisted reproduction. This chapter reviews the risks of venous and arterial thromboembolism associated with assisted reproduction, as well as available data regarding the impact of thrombophilia on the risks of thromboembolism and failure of implantation...

Scheduling gonadotrophin-releasing hormone antagonist (GnRH-ant) cycles for IVF intracytoplasmic sperm injection in patients is a challenge because of unpredictable ovum retrieval procedures on weekends, when less manpower is available. Recently, the use of GnRH-ant pre-treatment to delay an IVF and intracytoplasmic sperm injection (ICSI) cycle showed no negative effect on clinical pregnancy rates. An age-matched, case-control study was conducted to evaluate the effectiveness of such pre-treatment for scheduling purposes...

PURPOSE: To compare the embryo outcomes of in vitro fertilization/intra-cytoplasmic sperm injection with a gonadotropin-releasing hormone (GnRH) antagonist protocol with follicle stimulating hormone (FSH) and with human menopausal gonadotropin (hMG). METHODS: We performed a retrospective cohort study in 465 patients. Stimulation was started by daily FSH injection, and either FSH was continued (FSH alone group) or hMG was administrated (FSH-hMG group) after administration of a GnRH antagonist...
