Abstract

A method for producing, in a functionally agonadal human female body, an environment suitable for the implantation, nutrition, and development of an embryo, comprising the placement of at least one carrier containing at least one releasable steroid hormone into the vagina of the human female.

Claims

1. A method for producing, in a functionally agonadal human female body, an environment suitable for the phases of preparation for implanation, nutrition, and development of an embryo, comprising:

placing a carrier containing at least one releasable naturally occurring human steroid hormone into the vagina of said female body, thereby producing normal serum steroid hormone levels within each of said phases.

2. The method of claim 1, wherein said carrier is a solid material.

3. The method of claim 1, wherein said carrier is a silicone elastomer.

4. The method of claim 1, wherein said carrier is a polysiloxane.

5. The method of claim 1, wherein said carrier is polyethylene glycol.

6. The method of claim 1, wherein said steroid hormone is a combination of 17-beta-estradiol and progesterone.

7. The method of claim 1, wherein said carrier is shaped like a ring.

8. The method of claim 1, wherein a ring-shaped carrier is utilized in combination with an additional carrier of cylindrical shape.

9. The method of claim 1 and further including the step of subsequently substituting said carrier with at least one other carrier containing a different amount of said steroid hormone.

10. A method for augmenting, in a human female body, inadequate natural steroid hormone levels thereby stimulating the steroid milieu of the normal human female ovulatory menstral cycle, comprising:

placing a silicone elastomer carrier containing at least one releaseable naturally occurring human steroid hormone into the vagina of said female body, thereby producing normal serum steroid hormone levels.

11. The method of claim 10, wherein said carrier is solid material.

12. The method of claim 10, wherein said carrier is is a polysiloxane.

13. The method of claim 10, wherein said steroid hormone is a combination of 17-beta-estradiol and progesterone.

14. The method of claim 10, wherein said carrier is shaped like a ring.

15. The method of claim 10, wherein a ring-shaped carrier is utilized in combination with an additional carrier of cylindrical shape.

16. The method of claim 10, and further including the step of substituting said carrier with at least one other carrier containing a different amount of said steroid hormone.

17. The method of claim 10, including the step of producing normal serum steroid hormone levels for the phases of implantation, nutrition, and development of an embryo.

18. A method for simulating the steroid milieu of the normal human female ovulatory menstral cycle in a functionally agonadal human female body, comprising:

placing a silicon elastomer carrier containing and releasing a steroid hormone selected from the group consisting of 17-β

-estradiol, progesterone and the mixture of 17-β

estradiol and progesterone into the vagina of said female body, thereby producing normal serum steroid hormone levels.
