The performed cytogenetic analysis included 454 young Leine ewes, aged 3-8 months, coming from heterosexual twins and multiplets. Out of them, the studied 431 animals had a normal diploid chromosome number - 54,XX. Leukocytic 54,XX/54,XY chimerism was identified in 23 young ewes, which makes 5.06% of the studied group of animals.
An ethno-botanical survey of Vijayapur district comprising five tehsils was conducted during February 2014 to December 2015. The main purpose of this survey was to document the traditional use of medicinal plants for primary infertility in women in vijayapur district. 13 species belonging to 13 genera and 12 families were found to be used to treat primary infertility. The scientific name, family, local name, habit along with part used and mode of their administration are provided.

The clinical effects of twenty different chromosome anomalies in sheep are reviewed. It is concluded that not all anomalies give rise to reproductive problems or phenotypic variations. In particular, the centric fusion translocations appear not to have affected fertility and they have been helpful in determining the karyotype of the sheep.
A significant increase in the incidence of obesity, which has taken place in recent years caused that began to talk about the epidemic of obesity. This problem is characteristic of highly developed countries. Increasingly, also occurs in developing countries, including Polish. It occurs in all age groups and in almost all social groups. The disease is currently diagnosed in almost 25% of the Polish population. Increasingly, it is also diagnosed in young women and pregnant women. The literature increasingly emphasized the importance of obesity in disorders of insemination and proper implantation the fertilized ovum. For women who are overweight and obese, more often than women with normal body weight, comes to ovulation disorders and disturbances in the proper implantation of the fertilized ovum. These disorders result from the accumulation of adipose tissue and hormonal disorders resulting from them. Influence on fertility of women have not only expressed as their body weight BMI, but also as the content in the body fat and its distribution. The higher the fat content in the body making it harder and longer may be infertility treatment. It also noted the relationship between fat distribution and duration of treatment of infertility and its effect. More and more often also emphasized the importance of incorrect diets in young women as a factor in reducing fertility. This article is an attempt to collect and characterize the major causes of infertility seen in young women who are overweight or obese.
A general list of people, which was made in 2002, proved, that demographs are right, natural increase level in Poland is decreasing very fast. Reason of this should be looked for in decrease of amount of child from 204 by 100 women in 1990 to 137 by 100 in 1999. Things, which caused that state, are: 30% marriages in Poland can't have children, change of hierarchy of life priorities, childless caused by choice, especially popular within group of young women with high economical status.

Childlessness and adoption: the experience of loss as a source of suffering

51%
The present work deals with the issue of child's adoption. Adoption is presented as a difficult (stressful) situation for the adopted child, but also for the childless married couple, who has decided to take in the orphaned child. Adoption as a difficult situation is connected with the experience of loss. The childless spouses experience the loss of their biological parenthood, the loss of their biological child, who died during the prenatal period or just after being born, but also the loss of the status of a "normal" family created in accordance with the normative model of a family. The adopted child, on the other hand, experiences the loss of biological parents and biological siblings, the loss of genealogical continuity and of "the bonds of blood". The child must be confronted with the fact that "one, to be adopted, must be first abandoned". The problem with the studies on adoption lies in their theoretical character. Because of that, the psychological understanding of adoption reality is limited.
Female infertility is an increasingly important problem in cattle, causing enormous costs and retarding genetic progress. Current attempts to improve fertility by genetic selection are inefficient due to the low heritability of the respective trait, i.e. the nonreturn-rate 90 days after first sernice (NRR 90). Thus novel phenotypic traits more closely related to fertility are urgently needed.Since a large proportion of pregnancy losses occur in the preimplantation period, the interaction between early embryos and their maternal environment is an attractive target for systematic investigations, which may uncover mechanisms underlying early embryonic death. Based on holistic transcriptome and proteome studies [Hiendleder et al. 2005, Wolf et al. 2006] we attempt to understand the quantitative biology of embryo maternal communication and the regulation of endometrial receptivity [Wolf et al. 2003]. A short-term goal is the development of array-based systems for the differential diagnosis of fertility problems and for evaluating the connection between metabolic disturbances and reproductive functions. A long-term goal is the identification of genetic variation affecting the fertility-related gene expression profiles in female reproductive tissues such as endometrium. The endometrium undergoes marked functional changes during estrous cycle and pregnancy. As the adjacent environment of the conceptus, it represents the maternal interface for embryo maternal communication, which is essential to maintain pregnancy. Transcriptome studiem provide the unique opportunity to assess molecular profiles changing in response to endocrine or metabolic stimuli or to embryonic pregnancy recognition signals [reviewed in Bauersachs et al. 2008, Spencer et al. 2008].
