Terms relating to fertility issues
From assisted hatching to cryopreservation to cervical mucus — our glossary explains the most important terms.
The absence of menstrual bleeding. A distinction is made between primary and secondary bleeding. In the case of primary bleeding, the woman has never had a period before, whereas in the case of secondary bleeding, the period suddenly stops.
A miscarriage is a premature termination of pregnancy.
In this additional treatment before transfer in IVF/ICSI, a small indentation is made in the egg membrane, which acts as a kind of predetermined breaking point when the embryo hatches and is intended to make it easier for the embryo to leave the zona pellucida at this point.
This is the complete absence of sperm cells in the ejaculate.
Basal body temperature curve
The basal body temperature curve helps to determine the fertile days. In a regular cycle, the temperature rises by 0.5° C after ovulation. This curve can be used to determine the temperature and thus also the fertile days.
This is the fusion of egg and sperm with the formation of a new cell nucleus.
An embryo that is already several days old (at least 5) and already has a small cyst in the centre.
A drug to be taken in tablet form for hormonal stimulation of the ovaries.
ES + 2
In fertility jargon, counting the days after ovulation to determine when a pregnancy test is useful.
Not allowed in Germany. In this procedure, a healthy woman donates eggs to a couple or a single woman after hormonal pre-treatment. These are fertilised with donor sperm or the sperm of the respective partner. The resulting embryos are then transferred into the uterus of the woman who receives the donation.
A disease that results in a dispersed uterine lining. This often leads to adhesions in the abdominal cavity.
Fertility (from fero = I bear; give birth); originally the ability to carry a pregnancy to term. Today, in general: the ability to reproduce (= procreate).
The follicles in the ovary. Normally one follicle grows in each cycle. The egg develops in it and enters the fallopian tube during ovulation.
Follicle-stimulating hormone. A hormone produced by the pituitary gland which causes the egg to mature in the ovary.
Hysteroscopy — using a special small optic to look inside the uterine cavity. This examination is done to rule out changes that could interfere with the implantation of the egg.
Corpus luteum; after the egg has left the follicle, a corpus luteum forms. This is when the corpus luteum hormone is produced.
The reduced production of the corpus luteum hormone in the second half of the cycle.
Sexual intercourse on schedule.
Human Chorion Gonadotropin: The hormone produced during pregnancy.
Term in fertility jargon for the waiting time after ovulation.
Insemination: Prepared sperm are injected into the uterus on the day of ovulation.
Intracytoplasmic sperm injection: After an egg has been fertilised in the laboratory with a selected sperm cell, it is transferred back into the uterus.
In Vitro Fertilisation: A type of assisted reproduction. In this process, egg cells are brought together with sperm cells in a vessel. Ideally, fertilisation occurs.
Clinic specialising in the topic of infertility
Storage of biological material in liquid nitrogen. This includes for example, the storage of oocytes or sperm cells.
Frozen oocytes in the pronuclear stage can be thawed after cryopreservation and transferred back into the uterus once an embryo has developed.
Also called assisted reproduction.
Luteinising hormone. This hormone is produced in the pituitary gland and is one of the hormones involved in the regulation of reproduction. In women, it promotes ovulation and the formation of the corpus luteum.
Menstruation is a recurrent bleeding at the end of a cycle.
The process of implantation of the fertilized egg into the lining of the uterus.
During implantation, there may be some bleeding.
Oligo-Astheno-Teratozoospermia. In this case, there are too few, malformed and poorly mobile sperm in the ejaculate.
The egg cell leaves the follicle and travels into the fallopian tube, where fertilization takes place.
Similar to the pregnancy test. Here, the hormone content in the urine is determined with the help of a test stick and thus the fertile days can be determined.
Method of using ovulation tests to determine whether pregnancy has occurred after ovulation.
Polycystic ovaries. In this case, too many follicles develop but do not mature. The result is that ovulation does not occur and cycles are too long.
Pregnant until proven otherwise
This deals with reproduction, as well as the basics and control of fertility and disorders.
Examination of the sperm or rather, the ejaculate. The most important parameters are: Number, motility and morphology of the sperm.
The donation of sperm for assisted reproduction.
Special preparation technique of sperm cells.
Refers to the precautionary freezing of unfertilised eggs or sperm without a medical background.
Day of the Involuntarily Childless
16th of May
The male sex hormone
Clinical picture that can occur after hormone treatment in the context of assisted reproduction.
Also known as male sterilisation. The vas deferens of the man are cut and then closed. This is used to prevent conception.
In women, refers to the hormonal adjustment with the transition from the reproductive to the post-menopausal phase.
The period between two menstrual periods.
Monitoring of the menstrual cycle by ultrasound.
A secretion of the female body that has different consistencies during a cycle.
Social freezing: success rates
What is the ideal age to freeze my eggs? This is an often asked question in the context of social freezing. A simplified answer would be that it is generally better to freeze at a younger age than at a later age. However, it is not quite that simple.
