The effect of androgen administration on in vitro fertilization outcome in poor responders undergoing ovarian stimulation with microdose protocol: A randomized clinical trial.

Objective(s): Patients with poor ovarian response who have reduced ovarian reserve sometimes despite the maximum dose of gonadotropins do not respond properly. Androgens have been shown to play an important role in the early follicular development and proliferation of granulosa cells. This study aimed to evaluate the effect of androgen administration on IVF outcome in poor responders.

Assessment of the effect of serum and follicular fluid vitamin D and glucose on assisted reproductive technique outcome: A cross-sectional study.

Background: Vitamin D and glucose play an important role in the female reproductive system.

Objective: The aim of this study was to assess the effect of serum and follicular fluid vitamin D on assisted reproductive technique (ART) outcomes.

Materials And Methods: 102 infertile women were enrolled in the study.

Effects of human chorionic gonadotropin intrauterine injection on oocyte retrieval day on assisted reproductive techniques outcomes: An RCT.

Background: Several mediators play an important role in implantation. One of these mediators is human chorionic gonadotropin (HCG).

Objective: To evaluate the effects of HCG intrauterine injection on the day of oocyte retrieval on the result of assisted reproductive techniques (ART).

Effects of Intraovarian Injection of Autologous Platelet-Rich Plasma on Ovarian Rejuvenation in Poor Responders and Women with Primary Ovarian Insufficiency.

Injection of intraovarian platelet-rich plasma (PRP) was recently presented in terms of improvement ovarian function in women with a poor ovarian response (POR) or primary ovarian insufficiency (POI). In a before and after study, 17 poor responder women and 9 women with the diagnosis of POI were recruited. The multifocal intramedullary infusion of 1.

Effect of adding letrozole to gonadotropin on in vitro fertilization outcomes: An RCT.

Background: Aromatase inhibitors prevent the aromatization of androgens into estrogens, which reduces the negative feedback of estrogen on the hypothalamic-pituitary axis. It is clear that increasing the secretion of follicle-stimulating hormones results in an increased follicular growth.

Objective: This study aimed to evaluate the effect of adding letrozole to gonadotropin on in vitro fertilization outcomes in normal responders.

Progesterone-primed ovarian stimulation in polycystic ovarian syndrome: An RCT.

Background: In vitro fertilization is an important therapy for women with polycystic ovarian syndrome (PCOS). The use of new ways of improving clinical results is yet required.

Objective: This study was aimed to investigate the efficacy of progesterone primed ovarian stimulation (PPOS) and compare with conventional antagonist protocol in PCOS.

The effect of catheter rotation during its withdrawal on frozen thawed embryo-transfer cycles outcomes: A Case-control study.

Background: Embryo transfer (ET) is the last and the most clinical process in assisted reproductive technology cycle. It has been suggested that cervical mucus interacts with an adequate embryo transfer in different ways. A few studies showed that catheter rotation could discharge mucus entrapped in the embryo to neutralize embryo displacement.
