Fertility is a unique concept, pertaining to an ability to reproduce. It's commonly worded as "ability to conceive children", and its quite complex at its core. In this article, we go over specifically female fertility and common causes of infertility within Turner Syndrome cases. We ask that viewers read this article with slightly more care, due to this being flagged as a more sensitive topic.
FEMALE OVULATION, MENSTRUATION & TREATMENT
Female ovulation is the uterus releasing an egg into the fallopian tube for potential fertilization. Several hormones are released to begin the ovulation process, but it ends with the luteinizing hormone (LH) causing the ovary to release the egg. The hormone progesterone is later released to prepare uterus for pregnancy regardless of fertilization status of the egg.
This thickens the uterus lining to prepare for a fertilized egg to exit the fallopian tubes and implant. This thick lining is required for safe implantation of the egg and ensures a healthy pregnancy should the egg fertilize. When the progesterone levels later decrease to normal the following days (should the egg have not implanted), the uterus lining is shed and the cycle repeats. This is the menstruation aspect of fertility.
The delicate process of menstruation and ovulation often leave much room for error leading to conditions like endometriosis in development.
WHAT IS FERTILITY LIKE IN TURNER SYNDROME?
Individuals with Turner syndrome often face issues with Fertility (commonly infertility) due to various disorders such as Primary Ovarian insufficiency (POI) and heighted apoptosis.

WHAT IS FERTILITY LIKE IN TURNER SYNDROME?
Individuals with Turner syndrome often face issues with Fertility (commonly infertility) due to various disorders such as Primary Ovarian insufficiency (POI) and heighted apoptosis. Primary Ovarian Insufficiency (POI) is a disorder affecting females producing a similar effect to early menopause*. This disease usually causes issues with ovulation and menstruation, creating an abnormal cycle. The largest difference between premature menopause and POI is primarily the fact that some function is partially retained, the key term being partially. There may be short bursts of fertility windows with ovulation, but it is unpredictable and rare. It was additionally previously known as Premature Ovarian Failure, but it was later renamed as the phrasing was misleading.
Oocyte apoptosis is highly linked to Primary Ovarian Insufficiency (POI), with oocyte apoptosis usually being listed as a primary cause of POI in all patients (regardless of Turner Syndrome diagnosis). Apoptosis itself is the egg quality filter of the ovary, killing off eggs of the fetus(s) that are harmful or defective while the uterus (and fetus) are developing in the womb. This process is accelerated and heightened with this disorder, as there are many more anomalies within the eggs. An example in turner syndrome is the lack of the X chromosome interferes with the eggs natural meiosis*, causing them to be eliminated from the body. Other scenarios are situations where the egg didn't communicate properly with their nurse or barrier cells surrounding them, causing them to die. This process is heavily involved with hormone signals as it interferes with estrogen* and inhibin* levels within the body, causing many wrong signals and potential error. By the time an individual with this disorder is born, they are already left with significantly fewer eggs than standard.
These are the primary cause of infertility in turner syndrome cases, causing fertility issues. It is noted it is still possible for most individuals to get pregnant and conceive despite turner syndrome, but it is noted that due to the nature of POI it is unlikely.
WHAT ARE TREATMENTS THAT MAY BOOST FERTILITY IN TURNER SYNDROME PATIENTS?
With the current modern technology, there is not a direct cure for that will solve POI and majority of other fertility ailments that impair fertility in turner syndrome. But, hormone involvement in this process does allow for majority of potential side effects to be mitigated with treatment. It is common for individuals with this ailment to undergo estrogen supplements or additional supplements for other hormones as recommended by their personal physician.
The fertility aspect of treatment is still advancing day by day, and alternative options also grow as well. In Vitro Fertilization (IVF), surrogacy, sperm banks, egg donation, are all possibilities for potential treatment or alternative. Facing issues with fertility is complex, so its recommended to receive treatment from medical personnel. Please do not take anything said here as medical advise, and seek professional assistance for any medical issues.
Menopause: Women towards their 40's-50's undergo a process called menopause in which they officially can no longer bare children and lose ovarian function.
Meiosis: The natural act of cell division related to sexual reproduction and genetic diversity
Estrogen: The female hormone responsible for regulating reproduction and many feminine body processes. Paralleled to testosterone.
Inhibin: A key complex hormone in regulating the pituitary-gondal feedback system and various other processes.
