Follicle size 11mm
Patients with a follicle of 11mm when measured through transvaginal ultrasound in 2D, at time of ovulation induction.
|
We will collect several blood samples:
A transvaginal ultrasound will be performed after day 8 of the cycle to evaluate a 2D measurement of the growing follicle, as well as a measurement of the endometrial thickness to evaluate readiness for ovulation induction.
The MAP will be measured at cycle day 7 and 7 days post-ovulation induction to follow cardiovascular adaptations.
When patient is deemed ready for ovulation based on follicle size, blood results and endometrium, she will be asked to inject Ovitrelle 250 micrograms to induce ovulation in a controlled and timed manner.

Follicle size 12 mm

The relationship between progesterone levels and different follicular sizes on day 7 post ovulation induction.
Časové okno: From the start of the menstrual cycle until 7 days after ovulation induction.

Estradiol evolution throughout the cycle and its relation to luteal progesterone levels.
Časové okno: From the start of a menstrual cycle until 7 days post-ovulation induction.
|
We will measure the estradiol on different moments throught the menstural cycle, and see how these levels correspond to later (luteal) progesterone levels.
|
From the start of a menstrual cycle until 7 days post-ovulation induction.

Indirect factors reflecting cardiovascular and renal adaptation in the luteal phase
Časové okno: From the start of the menstrual cycle until 7 days after ovulation induction.
|
We will measure these factors (MAP, progesterone, estradiol, serum sodium, chloride, carbon dioxide and osmolality, prolactin, direct renin, plasma aldosterone, NT-proBNP, relaxin-2 and VEGF) at day 8 of the cycle, as well as 7 days after ovulation-induction.
All these factors form a reflection of the body's cardiovascular and renal adaptation, and will be studied to estimate these adaptation at different follicular sizes.
|
From the start of the menstrual cycle until 7 days after ovulation induction.
