OBJECTIVE: To assess the practicality of using power Doppler (PD) to assess follicular vascularity at the time of oocyte retrieval. DESIGN: Prospective study. SETTING: University-affiliated IVF unit.
Oocyte
An immature ovum, or egg.
A "primary oocyte" has not yet completed its first maturation division. A "secondary oocyte" has completed its first division (via meiosis).
Oocyte: The female reproductive cell, also called an egg.
Other causes of infertility: These include immunological problems, chromosomal abnormalities, cancer, chemotherapy, and serious illnesses.
Oocyte Cryopreservation - Freezing Eggs for Future Use
Oocyte cryopreservation, the freezing of human eggs is an emerging bio-technology option that may one day replace the freezing of embryos.
OOCYTE RETRIEVAL: Oocytes (eggs) are aspirated from the ovarian follicles using a minor surgical procedure.
PELVIC INFLAMATORY DISEASE (PID): An infection of any of the pelvic organs that, if left untreated, may result in infertility.
OOCYTE - The biological term for an egg.
OVARIAN CYST - A fluid-filled sac within or on the surface of the ovary. The majority of ovarian cysts are not related to any disease and disappear without treatment within a few months.
Oocyte: The egg produced in the ovaries each month. Also called the ovum (gamete).
Oligo-Ovulation: Infrequent ovulation.
Oligospermia: Low sperm count.
Oocyte
The egg; the reproductive cell from the ovary; the female gamete; the sex cell that contains the woman's genetic information.
Donor Oocytes -- Eggs provided by donors to be fertilized by the husband / partner sperm. Some indications for use of donor eggs are advanced maternal age, ovarian failure or absent ovaries, and concern about inherited disorders ...
Direct Oocyte-Sperm Transfer (DOST) -- Involves transvaginal retrieval of eggs from the stimulated ovary, just as in standard IVF.
Oocyte retrieval, gamete retrieval, ovum retrieval, and reproductive cell retrieval is the process when a long needle is introduced through the vagina and into the ovaries to aspirate the follicles containing the eggs.
Oocyte - A female reproductive cell that is produced by the ovaries and released during ovulation. The ovum is about the size of a grain of sand and is the largest cell in the human body.
Oocytes are aspirated, allowed to fertilize in vitro and the conceptus transferred before cell division (cleavage).
Semen Analysis ...
Oocyte retrieval
A surgical procedure to collect the eggs contained within the ovarian follicles, either via laparoscopic or ultrasound-guided follicular aspiration through which a needle is inserted into the follicle, ...
Oocyte (Egg)
Also referred to as an ovum, or the reproductive cell produced in the ovaries each month.
Oocyte donor
A woman who donates an ovum or ova to another woman.
Ova, or oocytes, are the haploid female egg cells, and their role is to fuse with one sperm cell to form a fertilized zygote which will then grow in the uterus to form a developing fetus.
EGG (oocyte, ovum)- A female reproductive cell.
EGG RETRIEVAL- Aspiration of eggs from ovarian follicles. This may be done by ultrasound guided aspiration in order to locate the follicles in the ovaries.
Micromanipulation (also referred to as assisted fertilization): The use of special micromanipulative technology that allows operative procedures to be performed on the oocyte, sperm, or embryo.
Oocyte The ovum or egg; the female gamete. Oocyte Aspiration See Egg Retrieval. Oocyte Donation See Egg Donation.
Oocyte - The female sex cell that is produced in the ovaries (also see egg, ovum, gamete).
Oocyte retrieval - When a needle is inserted into the ovarian follicles to extract eggs during surgery.
Oocyte: The egg. Ovarian Failure: The failure of the ovary to respond to follicle stimulating hormone (FSH) stimulation from the pituitary because of damage to or malformation of the ovary, or a chronic disease such as autoimmune disease.
After the sperm enters the vagina and reaches the fallopian tubes, it fuses with the oocyte or the female egg to form a zygote
- Zygote: The zygote is the single cell fusion of the sperm and the ovum.
It produces the female egg cells necessary for reproduction, called the ova or oocytes. The system is designed to transport the ova to the site of fertilization.
Pregnancy occurs as the result of the female gamete or oocyte (egg) being penetrated by the male gamete spermatozoon in a process referred to, in medicine, as "fertilization", or more commonly known as "conception".
Successful fertilization of any kind requires a cell commonly known as an egg (or oocyte) from a female and sperm from a male.
The cause of a poor IVF treatment outcome may be due to poor oocyte quality with subsequent lower fertilization and/or implantation defects caused by a qualitatively poor endometrial milieu.
Assisted Reproductive Technologies include oocyte (or egg) donation, embryo donation, in vitro fertilization, artificial insemination and sperm donation. Within each of these areas there are several different medical procedures that are used.
The Committee concludes, however, that at present neither oocyte nor ovarian tissue preservation should be offered or marketed as a means to defer reproductive aging."
Research is ongoing and hopefully one day these treatments will become commonplace.
Egg: A female reproductive cell, also called an oocyte or ovum. Egg retrieval (also called oocyte retrieval): A procedure to collect the eggs contained in the ovarian follicles.
Eggs from women with high and low BMIs were more likely than eggs from normal-weight women to produce immature oocytes during an assisted reproductive technology (ART) cycle, ...
Higher doses of gonadotropins to stimulate the ovaries are necessary and a long list of negatives accompanies the women who seek IVF such as, lower peak estradiol levels, fewer oocytes obtained, more canceled cycles, ...
