Adequate availability and FSH sensitivity of ovarian antral follicles and coordination of their growth during controlled ovarian hyperstimulation (COH) rank among factors that may determine outcome, particularly in patients presenting ovarian function defects and so-called "poor responders." Growing evidence indicates that both factors are positively influenced by steroid hormone pretreatments. First, data from studies conducted in both animals and in women exposed to virilizing androgen doses indicate that androgen pretreatments may increase follicle responsiveness to FSH and/or the number of growing follicles in the ovary, thereby constituting an interesting perspective in the management of "poor responders...

Measurements of ovarian reserve play an important role in predicting the clinical results of assisted reproductive technology (ART). The ideal markers of ovarian reserve for clinical applications should have high specificity in order to determine genuine poor responders. Basal follicle-stimulating hormone levels, antral follicle count, and serum anti-Müllerian hormone (AMH) levels have been suggested as ovarian reserve tests that may fulfill this requirement, with serum AMH levels being the most promising parameter...

The efficiency of assisted reproductive technologies (ARTs) in nonhuman primates is low due to no screening criterions for selecting sperm, oocyte, and embryo as well as its surrogate mothers. Here we analyzed 15 pairs of pregnant and non-pregnant cynomolgus monkeys, each pair of which received embryos from one batch of fertilized oocytes, and found ratio of endometrial to myometrial thicknesses in abdominal ultrasonic transverse section of uterus is a reliable indicator for selection of recipients for embryo transfer...

BACKGROUND: Gonadotrophin-releasing hormone (GnRH) antagonists can be used to prevent a luteinizing hormone (LH) surge during controlled ovarian hyperstimulation (COH) without the hypo-oestrogenic side-effects, flare-up, or long down-regulation period associated with agonists. The antagonists directly and rapidly inhibit gonadotrophin release within several hours through competitive binding to pituitary GnRH receptors. This property allows their use at any time during the follicular phase...

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...

The Assisted Reproductive Technology (ART) was born in order to help couples with infertility issues in having a baby. The first treatments of IVF used the spontaneous cycle of the women, with the retrieval of only one oocyte. Further studies have shown that it is possible to induce ovulation by administrating gonadotropins during the menstrual cycle, in order to obtain a higher number of oocytes. Many stimulation protocols have been introduced for controlled ovarian hyperstimulation of patients undergoing in vitro fertilization treatment...

Cross-border reproductive care (CBRC) is a multifaceted phenomenon. It may involve both the movement of patients to undertake assisted reproductive treatment through technologies otherwise denied and the movement of assisted reproduction professionals, egg and sperm donors and surrogates, as well as the importing and exporting of gametes. The reasons for CBRC vary between countries. In this global landscape, the search for donor oocytes is one of the main reasons for patients seeking cross-border reproductive care...

Controlled ovarian stimulation, using a gonadotrophin-releasing hormone (GnRH) antagonist protocol, is a potential treatment option for women with a low response to other fertility treatments as it appears to be at least as effective as GnRH agonists (long protocol). However, previous studies have indicated that the administration of GnRH antagonist may cause an excessive reduction in endogenous luteinizing hormone (LH) levels. The use of recombinant LH (rLH) supplementation during ovarian stimulation is controversial...

BACKGROUND: Infertility is a condition affecting 10% to 15% of couples of reproductive age. It is generally defined as "the failure to achieve a clinical pregnancy after 12 months or more of regular unprotected sexual intercourse". The treatment of infertility may involve manipulation of gametes or of the embryos themselves. These techniques are together known as assisted reproductive technology (ART). Practitioners are constantly seeking alternative or adjunct treatments, or both, in the hope that they may improve the outcome of assisted reproductive techniques...

CONTEXT: Ovulation induction in patients with hypogonadotropic hypogonadism (HH) is a challenge to the treating physician. The threshold for ovarian response in HH may differ substantially from that of normal patients. To reach that threshold levels of follicle stimulating hormone, in a step-up protocol longer duration of stimulation is required in some cases so as to prevent multiple pregnancy and to eliminate the risk of ovarian hyperstimulation syndrome. AIM: To evaluate the duration of stimulation, quality of oocytes, and embryo, and the pregnancy outcome in the assisted reproductive technology (ART) cycles in patients with HH...
