Detailed Description
The study group will start ovarian stimulation randomly in different moments throughout the menstrual cycle.
Randomization will take place on day 2-3 of the menstrual cycle, according to a list of random allocation of treatments and egg-donors will be assigned to random start ovarian stimulation: During follicular phase starting at day 5,7,9,11 or 13 of the menstrual cycle and during luteal phase starting at luteinizing hormone (LH) peak +3,+5,+7,+9 or +11.
Egg-donors will receive urinary follicle stimulating hormone (FSH) 150-225 IU/d in gonadotropin-releasing hormone (GnRH) antagonist protocol with cetrorelix acetate 0,25 mg/d starting five days after ovarian stimulation and a GnRH agonist trigger with triptorelin 0,2 mg to induce the final follicular maturation. Transvaginal ultrasound and serum analysis (estradiol, progesterone, LH and FSH) will be included for cycle monitoring.

Experimental: Random start ovarian stimulation
Egg-donors will be assigned to random start ovarian stimulation: During follicular phase starting at day 5,7,9,11 or 13 of the menstrual cycle and during luteal phase at luteinizing hormone (LH) peak +3,+5,+7,+9 or +11. They will receive urinary follicle stimulating hormone (FSH) 150-225 International units / daily (IU/d) and five days later the gonadotropin-releasing hormone (GnRH) antagonist: cetrorelix acetate 0,25 mg/d will be added until achieving criteria for receiving triptorelin 0,2 mg to induce final follicular maturation. Egg collection will take place 36 hours later. Interventions:

Measure Description |
Time Frame |

|
Percentage of Mature Eggs
Time Frame: Up to 24 hours from the oocyte collection
|
When collected, eggs retain numerous cells (granulosa or cumulus cells) surrounding the oocyte; this structure is termed as the cumulus oocyte complex (COC).
Few hours later (2-4 hs), the oocyte is denuded from these cumulus cells, allowing for a clearer observation of the maturity status (presence or absence of a metaphase II) of the oocyte.
The percentage of mature eggs represents the proportion resulting from dividing the total number of COCs collected by the number of metaphase II oocytes and multiplied by 100.
