Trial Title: Frozen-thawed Embryo Transfer in a Natural Cycle: hCG Triggering Versus LH Home Test

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: NONE
- Phase: PHASE4
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~* - Patient with IVF or ICSI cycle and therefore having frozen-thawed embryos~* Regular menstruation cycle~* Patient's willingness to participate in the study~Exclusion Criteria:~* - Irregular menstrual cycle demanding preparing endometrium with hormones for frozen-thawed embryo~* No frozen embryos after IVF cycle~* Allergy to Pregnyl® or some of its ingredients in the medication or other contraindications due to Pregnyl®

- Gender: FEMALE
- Minimum Age: 18 Years
- Maximum Age: 42 Years
- Healthy Volunteers: f

Study Arms:
- Pregnyl (Human chorionic gonadotropin) (Type: EXPERIMENTAL): In this group, patients have natural cycle in frozen-thawed embryo transfer and the ovulation is confirmed by administration of hCG (Pregnyl® 5000 IU). The day of transferring embryo is depending on the day of administration of hCG and the age of the embryo. The day zero day is defined by ovulation triggered by hCG.
- Home ovulation test (Type: OTHER): The patients randomized to the LH surge group perform the ovulation home test daily from the urine. Thus, the ovulation in this group is corfimed by the urine test. The day of transferring embryo is depending on the positive ovulation test and the age of the embryo. The day zero day is defined by positive ovulation test.

Based on this trial design, predict the completion outcome and termination type (if applicable).
