1. A method of predicting the probability that a female subject will experience a live birth event from an IVF treatment, the method comprising the steps of:

  • (a) entering into a computer system,(i) a data set comprising fertility profiles of a group of female individuals, wherein successful and unsuccessful IVF treatments from the fertility profiles are identified within the data set,(ii) variables known to be associated with or influence a female individual'"'"'s chance of experiencing a live birth event, the variables comprising female age, clinical diagnosis;

    clinical treatment information, medication, previous infertility history, number of previous pregnancies, number of previous term deliveries, number of spontaneous miscarriages, body mass index, diminished ovarian reserve, endometriosis, hydrosalpinx, polycystic ovarian disease, tubal disease, tubal ligation, male infertility, male infertility causes, unexplained female infertility, uterine fibroids, other causes of female infertility, contraceptive use, number of motile sperm before wash, number of motile sperm after wash, number of total motile sperm after wash, number of total motile sperm before wash, and day 3 follicle stimulating hormone (FSH) level, and(iii) variables known to be associated with or influence a female individual'"'"'s chance of having a live birth from an IVF treatment, the variables comprising sperm collection, sperm from donor, age of sperm donor or male partner, methods and origin of sperm collection, endometrial thickness, ultrasound monitoring results, oral contraceptive use, flare protocol, IVF protocol, total amount of gonadotropins administered and/or required, performance of ICSI (intracytoplasmic sperm injection), total number of oocytes, number or percent of normal and mature oocytes, number or percent of normally fertilized eggs, number or percent of unfertilized eggs, number or percent of abnormally fertilized eggs, total number of embryos, assisted hatching, average grade of embryos, average number of cells per embryo, blastocyst development rate, compaction on day 3, rate of cleavage arrest, number or percent of embryos arrested at 4-cell stage, day of embryo transfer, number or percentage of 8-cell embryos, number or percentage of 8-cell embryos transferred, number or percentage of blastocysts, number or percentage of cryopreserved embryos, number or percentage of cryopreserved oocytes, type of catheter used, season of procedure, year of procedure;

    (b) using the computer system to analyze the fertility profiles of step (a)(i) and the variables of steps (a)(ii) and (a)(iii), wherein the computer system identifies variables from steps (a)(ii) and (a)(iii) that are predictive of a probability of a live birth event in a female individual undergoing an IVF treatment;

    (c) generating a prediction model using the computer system, wherein the prediction model comprises at least one algorithm that calculates the probability of a live birth event in a female individual undergoing an IVF treatment based upon the analysis of step (b);

    (d) validating the prediction model of step (c) against at least one independent data set comprising fertility profiles of a group of female individuals, wherein the fertility profiles of the female individuals of the at least one independent data set have variables that are correlated to the variables of steps (a)(ii) and (a)(iii) that were found to be predictive of the probability of the live birth event in step (b);

    (e) applying the validated prediction model of step (d) to the at least one independent data set to generate prognostic stratification of the independent data set, wherein the prognostic stratification is represented by percentile assignments representing a likelihood of the female individuals of the at least one independent data set to experience a live birth event from an IVF treatment;

    (f) entering into the computer system information from the female subject comprising (1) number of the female subject'"'"'s unsuccessful IVF treatments, (2) values for the female subject for the step (a)(ii) variables that were found to be predictive of the probability of a live birth event in step (b), and (3) values for the female subject for the step (a)(iii) variables that were found to be predictive of the probability of a live birth event in step (b), wherein the computer system applies the validated prediction model of step (d) and the prognostic stratification of step (e) to deliver the probability of the female subject having a live birth event from an IVF treatment and the percentile assignment of the female subject'"'"'s predicted probability relative to the female individuals in the at least one independent data set of steps (d) and (e); and

    (g) generating a fertility management protocol for the female subject based upon the predicted probability and percentile assignment of step (f).
