Total motile spermatozoa (TMS) [25] or total motile sperm count (TMSC) [26] is a combination of sperm count, motility and volume, measuring how many million sperm cells in an entire ejaculate are motile. Use of approximately 20 million sperm of motility grade c or d in ICI, and 5 million ones in IUI may be an approximate recommendation.
The process of spermatogenesis as the cells progress from primary spermatocytes, to secondary spermatocytes, to spermatids, to Sperm Cycle of the seminiferous epithelium of the testis Spermatocytogenesis is the male form of gametocytogenesis and results in the formation of spermatocytes possessing half the normal complement of genetic material.
The sperm–cervical mucus contact test is an in-vitro slide test used for detecting antispermal antibodies. [1] 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.
Sperm Chromatin Structure Assay (SCSA) is a diagnostic approach that detects sperm abnormality with a large extent of DNA fragmentation. [1] First described by Evenson in 1980, the assay is a flow cytometric test that detects the vulnerability of sperm DNA to acid-induced denaturation DNA in situ . [ 2 ]
Percutaneous epididymal sperm aspiration (PESA) is a technique used to determine sperm counts in the event of a possible blockage of the vas deferens. It is an alternative to microepidydimal sperm aspiration (MESA), and aims to address the technical difficulty and cost of MESA. [ 1 ]
Since the test is performed with fresh semen and the incubation requires only 10 minutes, it renders MAR test a quick and simple screening tool for ASA in human ejaculate. However, samples with very low sperm count (i.e. severe oligoastheno-, or even azoospermia) cannot be evaluated using this method. Also presence of debris or high viscosity ...

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.
