OBJECTIVES AND STUDY DESIGN The aim of this study was two-fold: to investigate the association of Assisted Reproductive Technology (ART) and small newborn size, using standardized measures; and to examine within strata of fresh and cryopreserved embryos transfer, whether this association is influenced by parental infertility diagnoses. We used a population-based retrospective cohort from Michig...
Infertility affects 10-15% of couples who are trying to conceive, and half of the cases are due to male infertility. Intracytoplasmic sperm injection is increasingly being used to overcome multiple sperm deficiencies. Due to its effectiveness, some have proposed ICSI as a solution for all cases of male infertility, regardless of the cause. Hence, even men with potentially treatable causes of in...
Since the successful introduction of in vitro fertilization in 1978, medically assisted reproduction (MAR) has proliferated in multiple clinical innovations. Consequently, egg cells have become an object of demand for both infertility treatment and stem cell research, and this raises complex legal, ethical, social and economic issues.In this paper we compare how the procurement and use of human...
In a recent meta-analysis reported in BJUI, Zhang et al. [1] looked at the peri-operative outcomes of robot-assisted partial nephrectomy (RAPN) vs those of laparoscopic partial nephrectomy (LPN). Their study represents the third metaanalysis carried out over the last year [1–3], which is testament to the growing interest on this topic that is driven by the rapid spread of robot-assisted kidney ...

abstract background: worldwide, infertility affects 10%-15% of couples and most of them seek medical help including assisted reproductive technology (art) treatments. undergoing art treatments create many physical and emotional burdens. this study examined the psychological consequences of infertility in iranian infertile males and females as well as their spouses, unlike previous studies that ...
background: based on classical two-cell, two-gonadotropin theory, in the follicle, follicle-stimulating hormone (fsh) and luteinizing hormone (lh) put on their main effects on the granulosa and theca cells. lh is essential for androgens production. androgens are used for estradiol production by granulosa cells. profound suppression of lh concentrations in some normogonadotropic patients can cau...
background: spontaneous occurrences of multifetal pregnancies always have been a medical problem. the risks of perinatal morbidity and mortality and maternal morbidity increase with enhancement of the number of fetuses. in our prospective experimental study, the outcome of twin pregnancy after assisted reproductive technologies (art) with and without multifetal pregnancy reduction (mfpr) is com...
background: improvement of assisted reproductive technique (art) results in higher pregnancy rates from positive beta hcg to take home baby statistics. despite developments in culture media allowing blastocyst stage transfer, some centers apply second, third and sometimes fourth day post injection for embryo transfer. this study aimed to compare their reproductive outcomes. methods : this pro...
In the present study we present the conditions offered to biotechnology development in Tunisia and we compare three main biotechnology applications which raise ethical and health problems: organ transplant, assisted reproductive techniques, and genetically modified organisms. We try to identify factors that have allowed success of the first two applications and failure of the latter. Conditions...
