Spermatozoa from 1 5 fertile men adhered to and penetrated 60% of hamster oocytes, whereas those from infertile men, with both normal and poor semen quality, failed to adhere or penetrate. The heterologous sperm penetration test offers a new approach to the . Tests for these steps (sperm penetration assay and IVF) are difficult to interpret as they involve 2 living cells, depend on the sequence of events and only final step can be observed. If sperm penetration test and fertilization is successful, then it is evident that at least .

Zona-Free Hamster Oocyte Penetration Test This test was performed as described in the WHO Laboratory Manual for the Examination of Human Semen and Sperm-Cervical Mucus Interaction [ 17 ]. Immature (4- to 6-wk-old) hamster (Mesocricetus auratus) females were superovulated by an i.p. injection of 25 IU of eCG (Syntex, Buenos Aires, Argentina. Inhibition of sperm penetration of zona-free hamster eggs by CFTRinh Besides sperm capacitation and the acrosome reaction, sperm penetration of zona-free hamster eggs assay (SPA) was used to assess the human sperm fertilizing capacity, in particular the ability of sperm-oocyte fusion.

These tests include sperm–ZP binding assay, capacitation, hyperactivation motility, inducibility of AR, and the ability of sperm to fuse with the vitelline membrane (zona-free hamster egg penetration test). Figure 1 shows the appropriate management plan for unexplained male infertility.

In particular tests for motility and the fertilizing capacity of spermatozoa are examined, motility tests and the zona-free hamster oocyte penetration test are particularly criticized. The Authors affirm that hamster oocyte tests carried out in the presence of A have shown to correlate with fertility in vivo and may be of critical value.

As a test for examining the ability of the sperm plasma membrane to fuse with the vitelline mem- brane of the oocyte, the zona-free hamster oocyte penetration test is extremely sensitive and has been shown to generate results that correlate with fertility in vivo (Aitken et al., a; Irvine and Aitken, ) and in vitro (Aitken et al., ).
