Androgens:

Male hormones, which also appears also in the female body. If the level in the blood is too high, the fertility can be disturbed.

up

 

Aneuplodie:

Incorrect distribution of the chromosomes.. The most frequent variation is trisomie, instead of normally double chromosome triple exist. This leads to the decease of the embryo or by the borne child to clinical picture, as for example: the Down-Syndrome.

up

 

Artificial Insemination:

Meaning generally the bringing together of sperms and ova. In narrower sense the synonyms term is used for IUI.

up

 

Assisted Hatching:

Embryos must hatch out of the stiff ovum cover (zona pellucida), before establishing themselves into the womb mucous membrane, in whose they were protected and have developed in the first five days. Through opening the ovum cover, for example, with a laser the hatching is made easier.

up

 

Blastocyst:

Embryonic stage on day 5-6 after the conception. Latest at that time the embryo must transferred into the womb.

up

 

Chromosomes:

Components of the cell-nucleus and holders of the genetic information. The human being owns 2x23=46 chromosomes. Two of these determine the gender. The cell-nucleus of a woman owns two X-chromosomes, the man owns one X- and one Y-chromosome. Whether a sperm carries X- or Y-chromosome, a boy or girl originates.

up

 

Corpus luteum:

The left-over of the follicle after the ovulation receives a yellowish colour and plays a role in the second part of the cycle for the maintenance of a possible pregnancy.

up

 

Cryo-preservation:

(Cryo from the Greek language: "chilly, frosty") Storage of ova or sperms at deepest temperatures. This normally occurs in liquid nitrogen by -196°C.

up

 

Down-Regulation:

Through medication the distribution of body owned hormones can be reduced. This can be an advantage with the stimulation therapy.

up

 

Ectopic pregnancy:

The establishment of an embryo in the Fallopian tubes, instead of the womb.

up

 

Embryo:

The melting together of semen and ovum and growing of a new cell-nucleus of the fertilised ovum is called embryo. After the 13th pregnancy week developing child is also called foetus.

up

 

Embryo transfer:

Embryos which were generated in the test tube are transferred with a thin catheter into the womb (normally 2 to 6 days after conception).

up

 

Endometriosis:

From the Greek language (endo=inside; metra=womb). Hereby, the womb mucous membrane settles on other places in the belly space and causes cycle pains. Endometriosis is a frequent cause for infertility.

up

 

Endometrium:

Womb mucous membrane.

up

 

Estroge:

(lat: oestrus= mating readiness; gen= generate) female gender hormone, which is formed in the ovaries and provides the building-up of the womb mucous membrane.

up

 

Fallopian tube (tubes)

A funnel-shaped canal between the ovary and the womb. To there the ova attain after the ovulation, then they are fertilised and wander as an early embryo through, before they establish themselves into the womb.

up

 

Follicle:

Liquid-filled vesicle in the ovaries, ovaries ovulation.

up

 

FSH:

Follicle-Stimulating-Hormone, which promotes the growth and development of the ova

up

 

Gametes:

Gender cells. A complex term for sperms and ova.

up

 

GnRH:

Gonadotropin-Releasing-Hormone: a hormone which releases LH and FSH.

up

 

GnRH-Agonist (GnRH-Antagonist):

A medication, which releases the hormones LH and FSH.

up

 

HIV-Infection:

Through the AIDS virus caused infection.

up

 

Hormone:

Carrier on information between the different organs of the body.

up

 

hCG (humane choriongonadotropin):

Hormone which is produced by early embryos and therefore used as a pregnancy proof. In the reproductive medicine it can also be used for releasing the ovulation.

up

 

hMG (humane menopausegonadotropin):

The hormone is won from women's urine after the menopause and is used for stimulation of the ovaries.

up

 

ICSI (Intracytoplasmic sperm injection):

Method of the artificial conception, by which a single sperm is injected with the help of a thin hollow needle into the ovum.

up

 

IUI (Intrauterine artificial insemination):

Transfer of sperms to the inside of the womb with help of a catheter.

up

 

IVF (In-vitro Fertilisation):

Literally: "In glass conception". Meaning the conception of an ovum outside the body.

up

 

Laparoscopy:

Belly reflection to explore the position, size and state of the belly organs. Here: above all, the ovaries and Fallopian tubes.

up

 

Luteinizing hormone (LH):

A hormone which affects the ovulation.

up

 

MESA (micro epididymale sperm aspiration):

A technology through microsurgery, whereas sperms are won from the epididymis, which then ICSI ova can be fertilised.

up

 

Myome:

Good-natured. Muscular tissue existing growth in the womb. Myome can be a reason for infertility or miscarriages.

up

 

Nidation:

Establishment of the embryo on day 6 after the conception into the womb mucous membrane.

up

 

Oocyte:

Ovum

up

 

Ovaries:

On both sides in the belly space of the woman established, about plum-sized organs building estrogen or gestagen and containing the ova, which are released with the ovulation in the monthly cycle.

up

 

Ovulation:

In the middle of the cycle one or several (follicle) vesicles burst and the ovum is set free.

up

 

Placenta:

In German "Mutterkuchen". An embryonic organ, which supplies the foetus in the womb with nutrients. After giving birth the placenta frees itself as an "afterbirth".

up

 

PCO (polycystic ovarian):

Clinical picture of the woman, by whom the ovaries show many small cysts and often the level of male hormones is too high. PCO can be a cause for infertility.

up

 

PN-Stage:

Fertilised ova in the pronucleus-stage. This ovum owns two recognisable nuclei and does not count yet as an embryo according the German law for embryo protection. After the nuclei melt together it is called Zygote.

up

 

Polar body:

The component of a mature ovum which originates from the ripen division (Meioses). It contains the same genetic information like the ovum.

up

 

Polar body diagnosis (PBD):

A method, which gives conclusion through an examination of the Polar body about the genetics status of the ovum.

up

 

PolScope:

The physical procedure which without influence of the ovum certain structures of the inside of the cell can be made visible, for example the division spindle.

up

 

Progesterone:

A hormone which is formed by the corpus luteum and prepares the womb mucous membrane for the nidation of the embryo.

up

 

Prolactin:

A hormone which is formed in the brain and gets the milk flow going in the mammary gland.

up

 

Puncture

Extraction of tissue through a small surgical operation. According to the IVF the follicle puncture is understood by this, i.e. the suction of liquid in the follicle of the ovary or the puncture of the testicle for the TESE.

up

 

Sterility:

Fertility, outgoing, if over a year of unprotected sexual intercourse no pregnancy enters.

up

 

Stimulation:

A part of the IVF-therapy, which by giving hormones a maximum of ova grows in the ovaries (normally 5-15).

up

 

TESE:

Testicular sperm extraction. Through extraction of tissue in the testicle, sperms can be won from men, if sperms are not found in their seminal liquid. These can be used through ICSI for a conception of an ovum.

up

 

Womb (Uterus)

Pears-shaped organ in the belly space of the women in which the child is carried. The womb begins with the uterine orifice to which the womb neck and womb cave joins. Both Fallopian tubes flow into the womb.

up

 

Zona Pellucida:

Cover of the ovum and the early embryonic stage. Before the establishment of itself (nidation) the embryos must hatch out of the cover.

up

 

Zygote:

Fertilised ovum after melting together of the two pronuclei (see PN-Stage). By law for embryo protection a zygote already counts as an embryo.
