About

The purpose of this study is to evaluate intravaginal culture using the medical device INVOcell to generate day 5 blastocysts in comparison to traditional IVF.

Full description

This is a Phase III, single center, open label randomized comparative trial to evaluate intravaginal culture using INVOcell vs. traditional IVF to generate day 5 embryos Pilot: 40 couples (80 patients), randomized to receive either intravaginal culture (n=20) using the INVOcell or traditional IVF (n=20) Primary Endpoints: Blastocyst generation rate: number of day 5 embryos of "good quality" defined as 2BB or greater (expansion of embryo 2,3,4,5 or 6 and inner cell mass and outer cell mass grades of A or B) or higher using the Gardner Grading System divided by the number of eggs incubated Patient acceptability of INVOcell and intravaginal culture.

Secondary Endpoints: Live birth rate: number of cycles with a live birth divided by the number of cycles with embryo transfers.

Clinical pregnancy rate: number of cycles with fetal heartbeat at week 7 divided by the number of cycles with embryo transfers.

Fertilization rate: Number of embryos obtained after incubation divided by the number of oocytes placed in the device.

Embryo transfer rate: Number of cycles initiated divided by the number of cycles with embryo transfers Miscarriage rate: Number of miscarriages divided by the number of cycles with embryo transfers Multiple rate: Number cycles with twins or triplets divided by the number of cycles with embryo transfers Miscarriage rate per clinical pregnancy: Number of miscarriages divided by the number of cycles with clinical pregnancy

Inclusion criteria

Couples who will participate to the study will be pre selected for the following major indications:

Women diagnosed with:

Tubal factor
Endometriosis (type I to II)
Ovulatory dysfunction (slight)
Multiple female factors (<2)

Males with slight male factor

Couples with:

Unknown factor
Multiple factors, from female and male origin (<2)
Other rare factors not excluded by the inclusion/exclusion criteria (e.g. cervical mucus immune factor not treatable by IUI)

The pre-selected couples will be included in the study only if they fulfill the more specific inclusion and exclusion criteria below.

Couples may be included in the study only if they have been informed about the study and have given their written consent.

Infertile couple with failure to conceive a recognized pregnancy after one year (or 12 menstrual cycles) of unprotected intercourse IVF has been determined by the physician to be their next treatment

Women included in the study should:

Be between the age of 18 and 38 (up to 38th birthday at the time of the enrollment).
Have had a normal gynecological examination and Pap smear in the last 12 months.
Have a normal follicle stimulating hormone (<10 mIU/mL) and E2 (<250 pmol/L) on Day 3, determined in the past 12 months
Have an anti-mullerian hormone >1 or <3 ng/mL
Have had a normal baseline pelvic ultrasound examination in the past 12 months
Have a normal uterine cavity as assessed in the past year by hysterosalpingogram, sonohysterography or hysteroscopy. Prior tubal ligation is acceptable.
Have had negative cervical tests for G.C and Chlamydia in the past 12 months. Have male partner with a normal semen analysis with a total number of > 15 million total motile spermatozoa with normal morphology or borderline normal morphology (> 3% with the strict criteria) and a progression rating of >2.
