- Teratozoospermia
-
Teratozoospermia - A spermocytogram with less than 40% sperm of normal morphology.
- Test Yolk Buffer
A medium that contain nutrients to extend the sperm's life for shipment. Contains egg yolk.
- Testes
Also known as the testicles, the paired male sex glands in which sperm and the steroid hormone testosterone are produced.
- Testicle
the male gonad; produces sperm and male sex hormones
- Testicles
-
Testicles - The two male oval-shaped sexual glands contained in the scrotum beneath the base of the penis. They produce the male hormone testosterone and the male reproductive cells, the sperm.
- Testicular biopsy
The excision of a small sample of testicular tissue for microscopic evaluation to determine sperm production.
- Testicular Failure
Occurs when the testes do not produce a normal number of mature sperm and when the hormones needed for normal sperm production (LH, FSH) are abnormally elevated.
- Testicular Torsion
Condition in which the testicle twists on itself, cutting off its own blood supply; it occurs most commonly in adolescents. Surgical correction is necessary as soon as possible to save the testicle. It is associated with excruciating testicular pain.
- Testosterone
The primary male sex hormone. A steroid hormone, or androgen, produced in the testes that affects sperm production and male sex characteristics.
- TET
-
TET(Tubal Embryo Transfer) - A process where a fertilized and divided egg is transferred to the fallopian tubes.
- Thyroid gland
the endocrine gland in the front of the neck that produces thyroid hormones, which regulate the body's metabolism
- Tocolytic
A drug that relaxes smooth muscles and therefore interferes with uterine contractions; frequently used to stop premature labor
- Total effective sperm count
an estimate of the number of sperm in an ejaculate capable of fertilization; total sperm count X percent motility X percent forward progressive motility X percent normal morphology
- Translocation
-
Translocation - Is a chromosomal abnormality which occurs when chromosomes break and the fragments rejoin to other chromosomes. There are many structurally different types of translocations. There is no loss of genetic material, although the breakpoint can cause disruption of critical gene or juxtapose of two genes to create a fusion gene that induces cancer. In general however, the problem with translocations occurs during meiosis and is manifest as reduction in fertility due to increased risk of producing abnormal gametes.
- Tubal ligation
The sterilization of a woman by surgical excision of a small section of each fallopian tube.
- Tuboplasty
plastic or reconstructive surgery on the fallopian tubes to correct abnormalities that cause infertility
- Tumor
an abnormal growth of tissue that can be benign or malignant (cancerous)
