Until now very little information exists regarding the early luteal serum progesterone profile after Human chorionic gonadotropin (hCG) trigger. This pilot study will help characterize the serum progesterone, 17-hydroxyprogesterone profiles in IVF patients and correlate progesterone, 17-Hydroxyprogesterone levels to ovarian follicles obtained after stimulation with exogenous gonadotropins.
The early luteal phase after IVF treatment is only scarcely studied. During IVF treatment the early luteinizing hormone (LH) activity deficit induced after ovarian stimulation with exogenous gonadotropins will be partly covered by the bolus of hCG used for triggering of final oocyte maturation due to the long half-life of hCG. In addition, the luteal phase will be covered by exogenous progesterone supplementation. After successful implantation the embryo itself will provide the supportive LH activity, securing the function of the corpora lutea. However, during the early luteal phase and peri-implantation, recent data suggest that an early-mid-luteal hCG/LH deficiency exists after hCG trigger during which the corpus luteum lacks an optimal stimulation. Furthermore, the early luteal progesterone profile in IVF differs significantly from the progesterone profile of the natural cycle, in which the peak is reached around the time of implantation. With this non-invasive trial, we wish to further explore the early luteal phase profiles of progesterone, 17-Hydroxyprogesterone and hCG in order to optimize current luteal phase support policies in IVF and hopefully increase ongoing pregnancy rates.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Collect blood samples Blood samples are collected on the following days after human chorionic gonadotropin (hCG) injection: Day 0, Day 1, Day 2, Day 3, Day 4, Day 5, Day 6
Diagnostic Test: Blood collection
A total of ten (10) blood samples (2ml/each) will be collected during the study. Blood samples will be collected on the following days for subsequent analysis of LH, Estradiol, hCG, progesterone and 17-Hydroxyprogesterone.
Serum concentrations of progesterone,17-Hydroxyprogesterone, LH, E2, and hCG during early luteal phase
Blood samples are collected at ten points of time.
Time frame: In 6 days after human chorionic gonadotropin injection
Number of follicles ≥ 11 mm luteal phase
Number of follicles are counted by ultrasound.
Time frame: On the day of hCG injection
Plan to share: No
