a bstract background: non‑medical utilization of pre‑implantation genetic diagnosis (pgd), like sex selection, is increasing, therefore it is necessary to follow‑up the health and outcome of fertilization and newborn’s birth followed pgd. the aim of this study was to evaluate the outcome of fertilization after sex selection by pgd and the relation between the age of parents and the outcome of f...

OBJECTIVE This study aimed to assess predictive ability of heart rate variability (HRV) for pregnancy outcomes with in vitro fertilization (IVF) treatment. RESEARCH DESIGN AND METHOD A total of 180 women with 261 cycles of IVF and 211 embryo transfers (ETs) were analyzed. HRV was measured at four times during IVF treatment: the first date of menstruation, r-HCG (Ovidrel) administration, and b...

OBJECTIVE To review the outcomes of preimplantation genetic diagnosis (PGD) using zona drilling with acid Tyrode's solution (chemical zona pellucida drilling, chemical ZD) and those of partial zona dissection (PZD). METHODS Clinical outcomes of seventy-one couples undergoing 85 PGD cycles from January 2005 to December 2010 were included. Blastocyst formation and the hatching rate, clinical pr...

background: general concern is that the pregnancy rate is higher with gnrh-agonist as a protocol of pituitary suppression. gnrh-antagonist protocol provides a shorter period of administration and an easy flexible protocol. objective: in this study, the outcomes of gnrh agonist and antagonist in icsi cycles are compared in normo responder patients. materials and methods: in this randomized clini...

Objective Background: Oxidative stress as a potential cause of poor oocyte quality can influence female reproduction. This study aimed to investigate the effects of melatonin on chemical pregnancy rates of a significant number of polycystic ovary syndrome (PCOS) patients undergoing intrauterine insemination (IUI). MaterialsAndMethods Materials and Methods: In this randomized double-blinded clin...

OBJECTIVES The aim of the present study was to compare two procedures for sperm selection in ICSI cycles - conventional morphology sperm selection (ICSI-PVP) and chemical selection through Hyaluronan-treated petri dishes (PICSI), when male factor was associated. METHODS The evaluated parameters were semen quality, fertilization and cleavage rates, chemical and clinical pregnancy rates, as wel...

purpose: to assess whether bromocriptine-rebound method (brm) can improve pregnancy   outcomes compared to long protocol after intracytoplasmic sperm injection cycles (icsis).   materials and methods: a total of 114 women underwent icsi. pregnancy outcomes and   hormonal data were compared between two groups, i.e. long protocol and brm. ovulatory   women with normal serum prolactin levels were ...

background: gnrh agonist and antagonist were developed to control the premature release of lh surge. there is some difference between two protocols. objective: we compared the outcome of frozen-thawed embryo transfer in infertile women who used gnrh agonist or antagonist protocol for previous coh cycle and evaluation of any adverse effect of gnrh antagonist on oocyte and embryo. materials and m...
