the success rate of reproductive treatment methods depends on many different factors. the most important and discussed ones in the literature are maternal age, the causes of infertility, the ovarian response to stimulation, the influence of the male factor and sperm quality, embryo quality and the various uterine pathologies. some couples fail repeatedly after transferring good quality embryos ...

Over the years it has been an important goal to optimize the treatment of subfertility in order to obtain a better pregnancy rate and baby-take-home rate, usually combined with the goal of decreasing the rate of multiplet pregnancies. This implies optimizing the development of embryos through improved in vitro culture methods. And it also implies optimizing the methods of selection of embryos f...

BACKGROUND The latest studies reported that local endometrial injury is a useful method to improve the success of IVF-ICSI outcome. OBJECTIVE To assess whether local endometrial injury occurred by Pipelle in the spontaneous cycle could improve implantation rate, cleavage rate, and pregnancy outcome in the subsequent IVF-ICSI cycle in patients who had recurrent IVF failure. MATERIALS AND MET...

introduction: in this study human follicular fluid has been used as an enzyme- rich solution to prevent embryo implantation in mice which resulted in reduction of pregnancy rate. materials & methods: 2-6 month nih female mice were used to study the effect of interauterine follicular fluid on the fertility rate. 226 plugged female mice were caged in three groups: control, placebo, and experiment...

Background Levels of serum gonadotropins have direct effects on testicular functions and spermatogenesis. Assessment of levels of serum gonadotropins from fathered subjects and infertile patients indicates wide range diversity. In this study, we tried to find out whether the levels of seminal FSH and LH affect the parameters of seminal fluid analysis (SFA) and if there is any correlation betwee...

background: physalis alkekengi (p. alkekengi)has been used as an abortive plant in iranian traditional medicine for many years. objective: to investigate the effects of p.alkekengi on the fertility rate in female rats. material and methods: in this experimental study, 40 female albino rats were divided randomly into two groups; group 1/for investigating the implantation sites and group 2/ for i...

OBJECTIVE To describe a patient selection method for elective single embryo transfer (eSET), emphasizing inclusion criteria and results. METHODS This retrospective study included all cases seen in a private clinic between June 2011 and December 2016, in La Paz, Bolivia (3600 meters above sea level). Elective single embryo transfer was the method of choice in 34 IVF/ICSI cycles, all in the bla...

OBJECTIVE To determine how short and long term complication rates after pacemaker implantation are influenced by patient morbidity, operator experience, and choice of pacing system. DESIGN Retrospective analysis of 1884 patients who received VVI (n = 610), VDD (n = 371), or DDD devices (n = 903) between 1990 and 2001. Follow up period was 64 (34) months. The influence of age, sex, coronary ar...

Abstract Background Standard morphologic evaluation has been the most widely adopted approach to embryo selection, and remains common strategy.The objective of study determine association between grading implantation rate euploid blastocysts in single frozen-thawed transfer (SET) cycles. Methods A total 271 patients aged 20–40 years undergoing SET from January 2017 December 2019 were included r...
