- Salpingitis isthmica nodosa
an abnormal condition of the fallopian tube where it attaches to the uterus, characterized by nodules
- Salpingostomy
A surgical attempt to recreate the normal fallopian opening and fimbria function in cases of complete occlusion of the fallopian tubes. An incision in a fallopian tube, such as to remove an ectopic pregnancy.
- Salpingotomy
an operation to open a blocked fallopian
- Scrotum
the sac containing the testicles, epididymis, and vas deferens
- Secondary infertility
Infertility in those who have previously been fertile.
- Semen
A fluid consisting of secretions from the male's seminal vesicles, prostate, and from the glands adjacent to the urethra. Semen carries sperm and is ejaculated during intercourse.
Only a small part of the visible ejaculate (semen) comes from the testicle.
- Semen analysis
Evaluation of the basic characteristics of sperm and semen, such as appearance, volume, liquefaction and viscosity, and sperm concentration and motility. The presence of bacterial infection and immunological disorders can also be determined by semen analysis. It is the fundamental diagnostic method used to evaluate male infertility.
- Semen Collection Condom
A special condom used to collect semen for analysis or insemination. The advantage is the semen can be collected via normal sex instead of masturbation.
- Seminal Vesicles
Two pouch-like glands located above the prostate that produce seminal fluid and fructose, which make up the majority of fluid expelled during ejaculation.
- Seminiferous tubules
The network of tubes where sperm are formed in the testis.
- Septum
A wall that divides a cavity in half, such as a uterine septum
- serophene
A fertility pill that stimulates ovulation through release of gonadotropins from the pituitary gland. CC is a commonly prescribed fertility drug, primarily used in patients with oligomenorrhea to promote increased gonadotropin secretion and stimulation of the ovary.
- Sertoli cells
The cells in the testicles that provide nourishment to the early sperm cells
- Sexual dysfunction
The inability to achieve normal sexual intercourse for reasons such as impotence, premature ejaculation, and retrograde ejaculation in the man or of vaginismus in the woman.
- Sexually transmitted disease
Infectious diseases transmitted primarily by sexual contact, including syphilis, gonorrhea, chlamydia, herpes, and acquired immunodeficiency syndrome.
- SPA
A test that evaluates the ability of human sperm to penetrate an ovum by incubating sperm with hamster oocytes that have had their outer layer removed. Normal sperm will penetrate the eggs.
The reliability and significance of this test are controversial.
Also called Hamster Zona-Free Ovum (HZFO) Test or Sperm Penetration Assay (SPA)
- Sperm
The male reproductive cell, or gamete. Normal sperm have symmetrically oval heads, stout midsections, and long tapering tails.
- Sperm antibodies
-
Sperm antibodies (immunological response) - Antibodies against sperm cells which may attack and destroy them. These antibodies can be produced either by men against their own sperm or by the woman.
- Sperm bank
A place in which sperm are stored by cryopreservation in liquid nitrogen for future use in artificial insemination.
- Sperm count
The number of sperm in the ejaculate (when given as the number of sperm per milliliter it is more accurately known as the sperm concentration or sperm density)
- Sperm motility
The ability of a sperm to move normally.
- Sperm penetration assay
A test that evaluates the ability of human sperm to penetrate an ovum by incubating sperm with hamster oocytes that have had their outer layer removed. Normal sperm will penetrate the eggs.
The reliability and significance of this test are controversial.
Also called Hamster Zona-Free Ovum (HZFO) Test or Sperm Penetration Assay (SPA)
- Sperm preparation
The separation of viable sperm from the overall sperm population of an ejaculate for the purposes for intrauterine inseminations and ART procedures.
- Sperm washing
The dilution of a semen sample with various tissue culture media in order to separate viable sperm from the other components of semen.
See Sperm Preparation
- Spermicide
an agent that kills sperm
