Male Factor Infertility

Offering one of the most affordable fertility treatment options.

Male factor infertility is a complex problem and requires the expertise of specially-trained professionals who stay abreast of new developments in the field. Both the diagnosis and treatment of the male factor infertility has made significant progress in recent years. We have attempted to outline both the basic and advanced tests and procedures available at Coastal Fertility Medical Center. We hope you find the information helpful in this rapidly advancing field.

What is Male Factor Infertility?

In order for a pregnancy to occur, sperm must travel from the male genital tract to the egg in the female and then penetrate the egg. This requires sufficient numbers of not only moving but functioning sperm that have the ability to undergo the biochemical process that enables them to fertilize an egg. An impairment in any aspect of this chain of events is called male factor infertility.

How is Male Factor Infertility Diagnosed?

There is no single test to diagnose for male factor infertility. A work-up for male factor infertility may include: An analysis of the number of sperm (count); how many are moving (motility), and what sperm look like (morphology). Tests to identify sperm antibodies to determine the capacity of sperm to function (computer assisted semen analysis; CASA) and to assess the sperm’s ability to attach to (zona binding) and penetrate the egg (sperm penetration assay; SPA) may also be performed. Physical examination and semen culture can also be important components of the male work-up.

Complete Semen Analysis

A complete semen analysis provides the basic starting point in any work-up for male factor infertility. It consists of a sperm count, sperm motility, sperm morphology, live-dead ratio, and cellular content at the microscopic level. In addition, macroscopic observations of the semen volume, color, pH, and viscosity are also reported. Recent advances in the analysis of these parameters include strict morphology (Kruger criteria) for patients with increased abnormal forms or low motility and CASA for poor motility or idiopathic infertility.

Sperm Antibodies

The presence of antisperm antibodies can often be detected by the coagulation or clumping of sperm observed during a semen analysis. Also, unusually low sperm numbers or the presence of “twitching” sperm movement in the cervical mucus following a post-coital examination can often be an indicator of antisperm antibodies. Antibodies to sperm are frequently observed in patients that have undergone vasectomy reversal. By severely inhibiting sperm motility or sperm binding to the egg, sperm antibodies are a major causative factor in male infertility.

Sperm Penetration Assay (SPA)

The ability of human sperm to attach to and penetrate zona-free hamster eggs is highly correlated with their ability to fertilize human eggs. Men with normal semen analyses often display poor penetration due to incomplete capacitation of the sperm. If sufficient numbers are available, the sperm specimen can be split among 2-3 different preparations in an effort to identify the best treatment for IUI cycles or In Vitro Fertilization. The standard preparation is with isolate separation and then additional adjuvants such as test yolk buffer, follicular fluid, high salt or high protein may be included to improve the results. Furthermore, the average number of sperm penetrating the egg (penetration index) is a useful marker for deciding whether or not Intracytoplasmic Sperm Injection (ICSI) would be the most efficacious treatment to achieve fertilization.

If an abnormality is found, what treatments are available?

The male may undergo medical or surgical treatment appropriate to their medical condition. Additional treatment may include artificial insemination (AI) of the male’s partner with sperm that has been treated with a variety of methods. Some couples will undergo In Vitro Fertilization (IVF) using chemical enhancement for the sperm or Intracytoplasmic Sperm Injection (ICSI).

Anodiant Separation

Isolate is the standard method of separating progressively motile sperm from non-motile sperm and cellular debris found in semen. The concentration of Isolate used, length of the Isolate column, and speed of centrifugation may all be adjusted to improve sperm separation and recovery in male factor cases that are not severe.

Chemical Enhancement

A number of chemicals have been identified which can be used to improve the quality of the specimen prior to insemination either vivo or in vitro. In general, these chemicals act by either improving the motility of many slow-moving sperm or improving the capacitation process. Repeated CASA and/or SPA following the use of adjuvants often reveals dramatic improvements in results. Examples of motility enhancers include chymotrypsin, pentoxifylline and deoxyadenosine, whereas TEST-yolk buffer, follicular fluid, high salt, and high protein have been shown to improve capacitation.

Micromanipulation

Male factor patients who show severely reduced sperm numbers, motility, or function often benefit from In Vitro Fertilization in combination with Intracytoplasmic Sperm Injection (ICSI). An ICSI procedure can also be successfully applied to couples in which sperm can only be obtained through a testicular biopsy specimen. The biopsy is performed by a Urologist, usually on the day before the oocyte retrieval.

At-Home Semen Analysis
