Filter by:Fertility management refers to the entirety of practices that allow families to have as many children as they want and when they want, prevent unwanted pregnancies, regulate the time between two births and receive help in having children in the case of infertility. According to the Turkey Demographic and Health Survey 2018 data, 70% of women in Turkey who are currently married do not use any contraceptive method. Based on the same data, the rate of the unmet need for fertility management is 12% nationwide, 14% in eastern provinces, and 17% in women at the ages of 20-24. These rates show that the rates of unmet fertility management needs in Turkey are still not on the desired level. The fact that eastern provinces of Turkey have the lowest rate of modern contraceptive method use as 43% and a high rate of unmet fertility management needs as 14% suggests that it is needed to increase the effectiveness of fertility management counseling and reach more women. In these eastern provinces, especially women living in rural areas do not have easy access to these services due to the high prevalence of adolescent marriages, lack of transportation opportunities, healthcare personnel and healthcare services, and unpredictable weather conditions.
During the last decades, there was an improvement of the cancer treatments of the woman and the teenagers. Therefore higher survival rate is described. However, cancer treatments can alter the reproduction functions and reduce considerably the window of the fertility to the adulthood. Therefore, it is recommended to proceed to a fertility preservation by oocytes vitrification when it is possible. The vitrification is a freezing technique allowing high survival rate and similar results by assisted reproductive technologies compared with the use of fresh oocytes. An innovative method of automated vitrification was recently developed. The usual protocol consist to vitrify mature oocytes. However, this strategy cannot be used for hormone -sensitive cancer or when ovarian stimulation is not possible. In these situations, immature oocytes can be collected. It is also necessary to realize an in vitro maturation step for a use by assisted reproductive technology. According to the recent data of the literature, it remains unclear whether the vitrification of ovocytes must be performed before or after in vitro maturation (IVM). Therefore the aim of this study is to study the impact on structure and functions of ovocytes when vitrification is performed before or after IVM. The vitrification will be performed by a semi-automatic method which is an innovative method.
In vitro fertilization (IVF) treatment is now commonly used to treat infertile couples. During IVF treatment, oocytes and sperm are routinely incubated overnight and this may lead to suboptimal culture conditions because of increased reactive oxygen species (ROS) produced by sperm in the standard incubation. High levels of ROS can adversely affect the quality of the embryos, result in hardening of the zona pellucida and impair the implantation capacity of embryos. Studies shows successful fertilization of an oocyte occurs 20mins after the gametes are put together. Sperm can penetrate through the cumulus cells within 15min, and 80% of oocytes can be fertilized when they are exposed to a large number of spermatozoa within 1hr. As an attempt to avoid possible detrimental effects on the oocytes from long exposure to sperm, the brief incubation insemination protocol was developed. It implies that prolonged incubation of oocytes and sperm may not be necessary and may even be harmful. Some reports suggest that a sperm-oocyte exposure time of 1-6 h improves IVF outcomes. However, other studies report no such advantage with a short insemination time . A recent meta-analysis shows brief incubation of gametes was associated with significantly higher rates of clinical pregnancy , ongoing pregnancy and higher rate of implantation than standard incubation. But the rates of normal fertilization, good quality embryos and polyspermy were not significantly different compared with standard incubation. In a Cochrane meta-analysis, eight RCTs with 733 women were included, and showed similar results. But it only reported clinical pregnancy rate and ongoing pregnancy rate which were significantly higher in brief incubation group than standard incubation. However, the live birth rate, which is the important outcome parameter, was not reported in all these studies. It is uncertain whether brief incubation improves the life birth rate compared with standard incubation. The aim of this randomized double blinded study is to compare the live birth rate of IVF treatment following brief incubation of oocytes and sperm versus standard incubation. The hypothesis is that a brief incubation improves the live birth rate of IVF treatment.
If a termination of pregnancy procedure is performed by vacuum aspiration our patients receive a paracervical block. Nevertheless these patients are not free of pain. We randomised our patients: one group will receive additional orodispersible tramadol, the other group will receive a placebo.
we will use testicular tissue from patient who underwent orchidectomy due to medical reasons and test the viability of the tissue after cryopreservation and de-freezing.
The aim of this study is to examine whether incubation of human oocytes until pronuclear stage, in different culture media containing high and low concentrations of glucose affect fertilization differently, not only in standard IVF cycles, but also after intracytoplasmatic sperm injection.In addition, we wish to determine whether exposure of oocytes to different concentrations of glucose until pronuclear stage has further effect on embryo quality and development until the blastocyst stage.
this study will try to determine whether serum levels of insulin like growth factor are higher in fertile women than infertile women.
