Abstract:
Testicular Regression Syndrome (TRS) is defined as the absence or an incomplete development of the testis of varying degrees in 46XY patients with normal external genitalia. The prevalence ranges from 3-20% of cases previously diagnosed as cryptorchidism. We report the case of a 7-year-old boy who underwent surgical exploration with an initial diagnosis of cryptorchidism. Testicular structure was not identified and presumed testicular remnants were sent for histological analysis. The histological sections showed a fibrovascular nodule, structures of the spermatic cord and calcification, supporting the diagnosis of TRS.

Multiple Regression
Farmers can use multiple regression to determine the crop yield based on more than one factor, such as water availability, fertilizer, soil properties, etc. Here, the crop yield is the response or dependent variable as it depends on the other independent variables. The analysis requires the construction of a scatter plot...

Regression Analysis
In regression analysis, a regression equation is determined based on the line of best fit– a line that best fits the data points plotted in a graph. This line is also called the regression line. The algebraic equation for the regression line is called the regression equation. It is represented as:
