The Influence Of Intrauterine Pressure On Embryo Retention In A Catheter After Embryo Transfer.

The retention of the embryo in the transfer catheter after embryo transfer (ET) during in vitro fertilization is a very common phenomenon, encountered by even the most experienced operators, and embryos retained in the transfer catheter or its sleeve require a repeat transfer. The exact mechanism of embryo retention has not been explained. Therefore, the present study aimed to investigate the mechanism of embryo retention in the catheter during embryo transfer by using a transparent uterus model equipped with pressure sensors and a video recorder.

[Influence of naloxone on uterine contractions in patients with primary dysmenorrhea].

Unlabelled: Dysmenorrhea is a common condition among women in childbearing age. An increased uterine contractions, resulting among others from increased vasopressin and oxitocin secretion, is considered as a main cause of the primary dysmenorrhea. The endogenous opioids play the important role in the control of oxytocin and vasopressin release from the pituitary gland.

[Influence of functional status of ovaries on results of controlled ovarian hyperstimulation].

Unlabelled: The controlled ovarian hyperstimulation is an integral part of infertility treatment. Its main objective is to obtain oocytes with a highest developmental potential. The stimulation protocols involving the gonadotropin-releasing hormone analogues and gonadotropins are considered as the most efficient.

[Etiopathogenesis of dysmenorrhea].

Dysmenorrhea is a common and frequently disabling condition among women of childbearing age. Based on results of large epidemiological studies, it is estimated that over a half of the population of young women suffers from dysmenorrhea. In spite of such a high frequency of this condition, its literature.

[Influence of the anti-inflammatory, anti-bacterial and anti-oxidative treatment combined with the dietary supplementation on sperm parameters].

Unlabelled: The severe oligospermia and lukocytospermia is diagnosed among 25-40% of the infertile patients despite the absence of any clinical manifestation of the inflammatory process. The white blood cells are the main source of the free oxidative radicals, which can injure the cell membranes and the sperm DNA integrity influencing the reproductive potential of the male gametes. The aim of study was to assess the influence of the anti-inflammatory anti-bacterial and anti-oxidative treatment combined with the dietary supplementation on sperm parameters in the patients with severe oligospermia and lukocytospermia.

[Thrombosis in the course of ovarian hyperstimulation syndrome].

A 28-year-old woman sought medical advice in the gynecology department because of infertility. Based on the results of the infertility workup, it was decided to apply in vitro fertilization treatment in her case. On the 12th day after embryo transfer, the patient was admitted to hospital because of nausea, vomiting, abdominal distention, and difficulties in breathing.
