background: phytoestrogens are some plant compounds with estrogenic biological effects which are found in many nutritional sources as soybean, flaxseed and sesame. vitex agnus-castus, also called vitex, owns phytoestrogenic properties. studies have showed that phytoestrogens have different impacts on the gestation process and reproduction indices. the present study is aimed at investigating the...

backgroundseveral studies have examined the relationship between human development index (hdi) and various health outcomes. the aim of this study was to investigate the relationship between hdi, and infant mortality rate, mortality rate of children under one year and under 5 years, maternal mortality rate, and total fertility rate.materials and methodsin this ecologic study, data on hdi, total ...

In the Netherlands a fertility index is introducing which describes the fertility of daughters of a bull. The index is based on two breeding values which are estimated for all bulls; non return after 56 days (NR56) and interval between calving and first insemination (ICI). These two traits are combined in an index: the calving interval index or CI-index. This index was developed after comparing...

OBJECTIVES To investigate, in a prospectively randomized trial, whether preoperative gonadotropin-releasing hormone (GnRH) therapy improves the fertility index in primary cryptorchidism. Cryptorchidism is a common condition with a high risk of infertility. Treatment with GnRH appears to improve fertility later in life by inducing germ cell maturation. METHODS A total of 24 boys, 12-123 months...

This study was carried out to evaluate the fertility status of soils in Ahiazu Mbaise, Imo State under three land use types using nutrient index method and fertility rating. Soil samples were collected from five sampling points each from three land use types at the depth of 0 20 cm. Samples were prepared and analysed for physical properties such as particle size distribution, bulk density, mois...
