Use of Stability Analysis for Long-Term Soil Fertility Experiments
Long-term fertility experiments with replications are often statistically analyzed as split plots in time. Years are often shown to be significantly different and the inconsistency of treatment effects over years enters into significant year-by-treatment interactions which are difficult to interpret. The objectives of this study were to evaluate long-term fertility experiments by stability anal...
متن کاملFertility preservation 3 Fertility preservation for age-related fertility decline
Cryopreservation of eggs or ovarian tissue to preserve fertility for patients with cancer has been studied since 1994 with R G Gosden’s paper describing restoration of fertility in oophorectomised sheep, and for decades previously by others in smaller mammals. Clinically this approach has shown great success. Many healthy children have been born from eggs cryopreserved with the Kuwayama egg vit...
متن کاملIncreased male fertility using fertility-related biomarkers
Conventional semen analyses are used to evaluate male factor fertility/infertility in humans and other animals. However, their clinical value remains controversial. Therefore, new tools that more accurately assess male fertility based on sperm function and fertilization mechanism are of interest worldwide. While protein markers in spermatozoa that might help differentiate fertile and infertile ...
متن کاملBoar fertility
The male part of fertility traits in pigs has not often been analysed because of missing semen quality data in the case of natural mating. With increasing AI in pigs more data about semen quality of boars is available, so its influence on litter size can be analysed on bigger data sets. With advanced recording systems, single matings are recorded and important economic traits like mating succes...
متن کاملFertility preservation
Fertility preservation procedures are indicated when it's predicted that there will be exposure to a cause of infertility. Mainly cancer treatment, such as chemotherapy, radiation, and surgery, may destroy a person's ability to have children later in life, and oncofertility research focuses on increasing fertility preservation options. Oncofertility is a subfield that bridges oncology and repro...
