Sperm–cervical Mucus Contact Test
The sperm–cervical mucus contact test is an in-vitro slide test used for detecting antispermal antibodies. It is one of the investigations done for infertility. It should not be confused with Kurzrock–Miller test, where there is interface between the two materials; whereas in this test the materials are thoroughly mixed. Procedure Equal quantities of sperm and mucus are mixed, so there is no interface. If there are antispermal antibodies present, more than 25% sperms show shaky movements.Padubidri; Daftary (2011). ''Shaw's Textbook of Gynaecology, 15e.'' p. 204. Cross-checking the cervical mucus with another donor semen will confirm whether antibodies are cervical or seminal.

Kurzrock–Miller Test
The Kurzrock–Miller test is an in-vitro test of sperm–mucus interaction. It consists of establishing an interface between cervical mucus and liquefied semen. It is one of the tests used for investigating infertility. Etymology The test is named after Raphael Kurzrock and Thomas Grier Miller. Interpretation # Negative test: Spermatozoa congregate on semen side of the interface, but do not penetrate it. # Abnormal: Spermatozoa penetrate the mucus, but rapidly become immobile or acquire shaking movement. # Poor: after penetration, spermatozoa do not progress farther than 500 μm. # Normal: Spermatozoa penetrate the mucus and >90% are motile with definite progression, crossing 3 cm at 30 minutes.Padubidri; Daftary (2011).

Hamster Egg Penetration Test
The hamster zona-free ovum test (HZFO test), or hamster egg-penetration test, or sometimes just hamster test, is an in-vitro test used to study physiological profile of spermatozoa. The primary application of the test is to diagnose male infertility caused by sperm unable to penetrate the ova. The test has limited value, due to expense and a high false negative rate. Procedure In this test, sperm are incubated with several hamster eggs. After seven to twenty hours, the number of sperm penetrations per egg is measured. The hamster eggs have had the zona pellucida, the outer membrane, removed—hence, ''zona-free''. Having all eggs penetrated by multiple sperm is considered to be a positive sign for fertility. Results suggest that men whose sperm fail the hamster test are a third as fertile than those whose sperm pass. Although medical professionals often present the procedure as unable to create an embryo, these claims are not technically correct. If the human sperm succeeds ...

Postcoital Test
The postcoital test (PCT), also known as the Sims test, Hühner test ,Sims–Hühner test, or cervical mucous penetration assay is a test in the evaluation of infertility. The test examines interaction between sperm and mucus of the cervix. The PCT examines sperm survival in cervical mucus during the pre-ovulatory period and determines whether sperm are migrating into the female reproductive system. It does not predict whether pregnancy can occur. The test is performed 1 to 2 days before ovulation, when estrogen-stimulated cervical mucus is abundant. Basal body temperatures or the midcycle luteinizing hormone surge may be used to determine the timing of the PCT. Mucus is withdrawn from the endocervical canal within 8 hours of coitus and examined. The presence of any forwardly motile sperm in alkaline mucus suggests adequate coital technique and a normal cervical mucus–sperm interaction. Procedure The PCT is scheduled close to ovulation when mucus is abundant, and the infertile c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medical Tests
A medical test is a medical procedure performed to screening (medicine), detect, medical diagnosis, diagnose, or monitoring (medicine), monitor diseases, disease processes, susceptibility, or to determine a course of treatment. Medical tests such as, physical and visual exams, diagnostic imaging, genetic testing, chemical and cellular analysis, relating to clinical chemistry and molecular diagnostics, are typically performed in a Medical laboratory, medical setting. Types of tests By purpose Medical tests can be classified by their purposes, including diagnosis, screening or monitoring. Diagnostic A diagnostic test is a procedure performed to confirm or determine the presence of disease in an individual suspected of having a disease, usually following the report of symptoms, or based on other medical test results. This includes posthumous diagnosis. Examples of such tests are: * Using nuclear medicine to examine a patient suspected of having a lymphoma. * Measuring the blood ...

Fertility Medicine
Reproductive endocrinology and infertility (REI) is a surgical subspecialty of obstetrics and gynecology that trains physicians in reproductive medicine addressing hormonal functioning as it pertains to reproduction as well as the issue of infertility. While most REI specialists primarily focus on the treatment of infertility, reproductive endocrinologists are trained to also test and treat hormonal dysfunctions in females and males outside infertility. Reproductive endocrinologists have specialty training (residency) in obstetrics and gynecology (ob-gyn) before they undergo sub-specialty training (fellowship) in REI. Reproductive surgery is a related specialty, where a physician in ob-gyn or urology further specializes to operate on anatomical disorders that affect fertility. Certification In a number of countries, the pathway to become a subspecialist in REI is regulated. Thus, in the United States, for instance, the American Board of Obstetrics and Gynecology (ABOG) and Amer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
