background: the selection of pre-embryos for transferred is based on morphological appearance. but some poor quality cleaved embryos also can be cultured to the blastocyst stage and implanted. objective: to assess the clinical pregnancy outcomes of blastocyst transfer which developed from poor quality embryos. materials and methods: a total of 109 cleaved embryos with poor quality were cultured...

Equine embryos were recovered nonsurgically 6.5 d after ovulation (Exp. 1) and those >200 tim were stored in one of three media: 1) Ham's F10 + 10% fetal calf serum (FCS) under 5% CO 2 , 5% O~and 90% No at 24 C (Ham's F10); 2) Minimal Essential Medium with Hank's balanced salts + 10% FCS in air (MEM) at 24 C or 3) MEM at 5 C n=lO/treatment). Embryos 4200/~m (n=10) were bisected microsurgically;...

OBJECTIVE The present study investigates pre- and post-implantation developmental competence of nuclear-transferred porcine embryos derived from male and female fetal fibroblasts. METHODS Male and female fetal fibroblasts were transferred to in vitro-matured enucleated oocytes and in vitro and in vivo developmental competence of reconstructed embryos was investigated. And, a total of 6,789 fe...

Embryo culture were used to produce inter specific walnut hybrid plants between Juglans nigra L. and J. regia L. Developed ovaries were collected from J. rejia female flowers which were pollinated with J. nigra pollen grain by high dusting on a mature tree. In order to isolate embryos, exocarps were aseptically removed. Isolated embryos from ovules at different developmental stages were transfe...

BACKGROUND Cell-cell communication and adhesion are essential for the compaction process of early stage embryos. The aim of this study was to develop a non-invasive objective calculation system of embryo compaction in order to test the hypothesis that embryos with a larger mean contact surface result in a higher live birth rate compared to embryos with a lower mean contact surface. METHODS Mu...

background: in recent years, the high likelihood of the implantation of transferred embryos has led to an increase in the number of multiple pregnancies and consequently an increased risk of complications in fetuses and mothers. since the aim of infertility treatment is the birth of a healthy child while preserving the mother’s health, therefore, attempts should be made to avoid multiple pregna...

background: there is increasing evidence that psychological factors like anxiety and depression can affect ivf/icsi treatment results. objective: this study aimed to clarify the role of women’s anxiety and depression on the outcome of art cycles using intra cytoplasmic sperm injection (icsi). materials and methods: this was a prospective pilot study. one hundred six (106) consecutive women unde...
