1. A system for determining a probability of achieving a pregnancy at a selected point in time, the system comprising:
- a central processing unit (CPU); and
storage coupled to said CPU for storing instructions that when executed by the CPU cause the CPU to;
accept as input, data representative of a plurality of fertility-associated phenotypic traits of a female subject;
analyze the input data using a prognosis predictor generated by;
obtaining a reference set of data from a plurality of women across one or more reproductive cycles, the reference set of data comprising fertility-associated phenotypic traits and known pregnancy outcomes, wherein the plurality of women accounts for a dropout population of women who ceased pregnancy attempts prior to reaching a live birth outcome and a non-dropout population of women who continued pregnancy attempts until live birth;
determining one or more correlations between the at least one of the fertility-associated phenotypic traits and the known pregnancy outcomes at a plurality of time points across the reproductive cycles, wherein the dropout population is accounted for by estimating a likelihood of dropout for each subject at each reproductive cycle and weighing the women in the non-dropout population proportionally to the likelihood of dropout; and
training the prognosis predictor on the reference set of data;
provide a probability of achieving a pregnancy for the female subject at a selected point in time as a result of running the prognosis predictor on said input data; and
treating the female subject with a fertility treatment based on the probability of achieving a pregnancy.

Abstract
The present invention generally relates to systems and methods for determining the probability of a pregnancy at a selected point in time. Systems and methods of the invention employ an algorithm that has been trained on a reference set of data from a plurality of women for whom at least one of fertility-associated phenotypic traits, fertility-associated medical interventions, or pregnancy outcomes are known, in which the algorithm accounts for any woman who ceases pregnancy attempts prior to reaching a live birth outcome.

17. A method for determining a probability of achieving a pregnancy at a selected point in time, the method comprising:
-
accepting as input, data representative of a plurality of fertility-associated phenotypic traits of a female subject; analyzing the input data using a prognosis predictor generated by; obtaining a reference set of data from a plurality of women across one or more reproductive cycles, the reference set of data comprising fertility-associated phenotypic traits and known pregnancy outcomes, wherein the plurality of women accounts for a dropout population of women who ceased pregnancy attempts prior to reaching a live birth outcome and a non-dropout population of women who continued pregnancy attempts until live birth; determining one or more correlations between the at least one of the fertility-associated phenotypic traits and the known pregnancy outcomes at a plurality of time points across the reproductive cycles, wherein the dropout population is accounted for by estimating a likelihood of dropout for each subject at each reproductive cycle and weighing the women in the non-dropout population proportionally to the likelihood of dropout; and training the prognosis predictor on the reference set of data; providing a probability of achieving a pregnancy for the female subject at a selected point in time as a result of running the prognosis predictor on said input data; and treating the female subject with a fertility treatment based on the probability of achieving a pregnancy. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

31. A method for determining a probability of achieving a pregnancy at a selected point in time, the method comprising, the method comprising:
-
inputting data representative of a plurality of fertility-associated phenotypic traits of a female subject into a computer; causing the computer to; analyze the input data using a prognosis predictor generated by; obtaining a reference set of data from a plurality of women across one or more reproductive cycles, the reference set of data comprising fertility-associated phenotypic traits and known pregnancy outcomes, wherein the plurality of women accounts for a dropout population of women who ceased pregnancy attempts prior to reaching a live birth outcome and a non-dropout population of women who continued pregnancy attempts until live birth; determining one or more correlations between the at least one of the fertility-associated phenotypic traits and the known pregnancy outcomes at a plurality of time points across the reproductive cycles, wherein the dropout population is accounted for by estimating a likelihood of dropout for each subject at each reproductive cycle and weighing the women in the non-dropout population proportionally to the likelihood of dropout; and training the prognosis predictor on the reference set of data; and provide a probability of achieving a pregnancy for the female subject at a selected point in time as a result of running an algorithm on the inputted data; and treating the female subject with a fertility treatment based on the probability of achieving a pregnancy. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38)
