The aim of this trial was to evaluate the effect of embryo cryopreservation techniques on the survivability of embryos and fertility following transfer to Boer goat does. The oestrous cycles of 27 mature recipients Boer goat does were synchronised using controlled internal drug release dispensers (CIDR’s) for 16 days. At CIDR removal, does were injected with 300 IU eCG. The recipient does were ...

BACKGROUND We often see patients with a thin endometrium in ART cycles, in spite of standard and adjuvant treatments. Improving endometrial growth in patients with a thin endometrium is very difficult. Without adequate endometrial thickness these patients, likely, would not have reached embryo transfer. OBJECTIVE We planned this study to investigate the efficacy of intrauterine granulocyte co...

To evaluate whether duration of autologous oocyte vitrification has an impact on in-vitro fertilization (IVF) cumulative live birth rates (cLBR) after fresh or frozen embryo transfers. We identified IVF cycles using vitrified/thawed oocytes from 2010-2020. Ovarian stimulation, vitrification/thawing, IVF/ICSI, culture/transfer were performed published protocols. Duration cryopreservation for the...

BACKGROUND The two main complications associated with the use of assisted reproduction techniques, ovarian hyperstimulation syndrome and multiple pregnancies, could be eliminated by milder ovarian stimulation protocols and the increased use of a single embryo transfer (SET) policy. A retrospective, cohort study was performed in private infertility centre to evaluate the embryological and clinic...

BACKGROUND Infertility is a common problem affecting up to ten per cent of married couples. A systematic evaluation of aetiologic factors forms the basis for choice of treatment and future fertility. On the global perspective, Assisted Reproductive Technologies (ART) has become internationally recognised treatment option for some infertile couples. A report on the current outcomes of ART practi...

BACKGROUND There are different methods in endometrial preparation for frozen-thawed embryo transfer (FET). OBJECTIVE The purpose of this study was to compare the live birth rate in the artificial FET protocol (estradiol/ progesterone with GnRH-agonist) with stimulated cycle FET protocol (letrozole plus HMG). MATERIALS AND METHODS This randomized clinical trial included 100 women (18-42 year...
