The aim of the study was to examine the in vivo viability of in vitro-produced (IVP) porcine embryos obtained from oocytes matured with thymosin. The research material for this study consisted of immature pig oocytes obtained from ovaries after slaughter and ejaculated semen obtained from one boar. The immature oocytes were cultured in vitro until the metaphase II stage in a medium supplemented with thymosin (TMS). The presumptive zygotes obtained were cultured in vitro for 4-40 hours. The presumptive zygotes and 2-4-cell embryos were evaluated in vivo after transferring them to synchronized recipients. After the transfer of embryos from the experimental group into 2 recipients (50 embryos into each gilt) and the transfer of 50 embryos from the control group into 1 recipient, both gilts that had received embryos obtained by in vitro fertilization of oocytes matured with TMS became pregnant and delivered a total of 16 live piglets. After the transfer of embryos from the control group, no pregnancy was achieved. In conclusion, the results of our preliminary study suggest that the maturation of pig oocytes with thymosin supports the in vivo survival of in vitro produced embryos. It is important to note, that this was the first birth of piglets obtained after transfer of IVP embryos in Poland.

This article presents reviews of literature sources on the issue of assessing the risk of developing gynecological cancer in women after an in vitro fertilization program. Infertility and infertile marriages have now become quite a big problem of modern medicine. Against the background of the unfavorable demographic situation in the Russian Federation, this problem is becoming quite urgent. The main way to solve this situation is assisted reproductive technologies, among which the most common is in vitro fertilization. The in vitro fertilization program is accompanied by a hormonal ovulation stimulation procedure to obtain a female germ cell capable of fertilization. Against the background of the active use of the in vitro fertilization procedure, many patients had concerns related to the risk of developing gynecological cancer after the IVF procedure, which is due to the use of hormonal drugs to stimulate the ovaries. Also of concern is the fact that certain types of cancer, including ovarian cancer, endometrial cancer and breast cancer, are hormone-dependent. In this regard, multiple large-scale studies were conducted, which showed that the risk of developing gynecological cancer is really increased in patients after the in vitro fertilization program. In particular, breast cancer in women after the in vitro fertilization program is more common by 10%, and in women without a history of pregnancy and over the age of 40, it is more common by 31%. The increased risk may be due to age-related vulnerability to the effects of hormones or higher doses of hormones during the IVF procedure. Ovarian cancer and endometrial cancer are also more common in patients after IVF. According to the research results, it is suggested that it is not the IVF procedure itself that causes the development of cancer, but excessive hormonal load of the body, which leads to the launch of carcinogenesis.
