BACKGROUND The transfer of cryopreserved embryos can be timed with ovulation in a natural cycle or after artificially preparing the endometrium with exogenous hormones. Progesterone is essential for the secretory transformation of the endometrium that permits implantation as well as maintenance of early pregnancy. The purpose of this study is to assess the effect of luteal phase supplementation...

An infertile couple came to our centre for semen cryopreservation. Husband was having nonseminomatous germ cell tumor of testis for which he was advised unilateral orchidectomy followed by chemotherapy. Being a medical professional he was aware of the impact of chemotherapy on the semen quality and the treatment modalities available for future conception. Four vials of semen were frozen over a ...

OBJECTIVE To investigate the reproductive outcome of artificial endometrial preparation with exogenous steroids for frozen-thawed embryo transfer with and without pre-treatment with depot gonadotropin releasing hormone agonist (GnRH-a) in women with regular menses. MATERIALS AND METHODS This is a prospective randomized clinical trial conducted in two ART centers on 176 women undergoing frozen...

Submit Manuscript | http://medcraveonline.com for 5 years due to polycystic ovary syndrome underwent some unsuccessfully low-complexity infertility treatments, then she underwent IVF/ICSI in October 2015. The patient opted for freezing-all embryos for subsequent transfer. In June 2016, two frozen-thawed embryos were transferred in the blastocyst stage. Twelve days after the embryo transfer, the...

Assisted Hatching (AH) is a technique performed after In Vitro Fertilization (IVF) and involves the artificial thinning or opening of the Zona Pellucida (ZP) prior to Embryo Transfer (ET) as an attempt to improve the probability of embryo implantation. AH can be performed by embryologists via mechanical, chemical, or laser-assisted means. A few studies suggest that a larger size of ZP opening/t...

The presence of multinucleated blastomeres (MNBs) in embryos is associated with poor developmental competence in assisted reproductive technologies. This phenomenon is observed not only in humans but also in other animal species. The purpose of the present study was to investigate the characteristics of embryos with MNBs (MNB embryos) that could be utilized in embryo transfer. The developmental...

BACKGROUND In couples presenting with retrograde ejaculation refractory to medical treatment, the first choice of fertility treatment should be Assisted Reproductive Techniques using rapidly purified spermatozoa retrieved from post-ejaculatory urine. The Hotchkiss technique and modified variants are simple and efficient for retrieving sperm from the bladder. We developed a new protocol, includi...

Infertility due to spinal cord injury (SCI) in young men is a frequent complication of their injury. When the simpler methods of management of the erectile and ejaculatory dysfunction that invariably follow the more severe types of SCI are not effective, then semen production by transrectal electroejaculation (TREE) combined with in-vitro fertilization (IVF) and embryo transfer is effective. A ...

Background: The objective of this study was to compare the pregnancy rate of Frozen-thawed Embryo Transfer (FET) on natural versus hormone replacement therapy (HRT) cycle endometrium, in patients with repeated IVF failure (RIF). Materials and Methods: In this observational study, the pregnancy rate after FET on natural endometrium in patients with RIF and previously poor endometrium (<7mm) on H...
