Sperm morphology, in the context of a semen analysis, refers to the size and shape of the sperm in a given semen sample. Otherwise, you could have fertility problems because of abnormal sperm morphology. A normal sperm has an oval head about micrometers long and 2. You may see a different number for normal on a semen analysis depending on what system is being used. This matters because having an abnormal shape might make it difficult for them to penetrate an egg.
This abnormality is stable over time. Gaining foreskin 4th edition of the WHO manual 9 completely adopted the strict Tygerberg approach. This is when there is no ejaculate and no sperm.

In Abnormal affecting fertility morphology sperm case, your doctor will remove immature but viable sperm cells directly from your testicles, mature them in the lab, and then use them for IVF-ICSI. If a positive action fertilihy made—ceasing cannabis use, losing weight, halting excess alcohol intake—we will see a morphologh from that action. On the basis of the predictive values from a multiple regression analysis to calculate the end points of regression lines, the proportion of spermatozoa with normal morphology declined from Abnormal Abnrmal morphology: What does it mean?

After a median follow-up time of 2. Strict morphology should not be used to predict fertilization, pregnancy, or live birth potential. Semen analysis is a critical tool in the assessment of the infertile male; however, the importance of sperm shape, or morphology, is controversial. The ability of sperm morphology to predict in vitro reproductive outcomes was first proposed by Kruger et al. These findings were propagated by a study published in The Lancet 3 that noted in men with an increased proportion of sperm with abnormal morphology, and the likelihood of pregnancy was decreased.
While sperm morphology is guided by specific criteria, it still remains subjective to inter- and intra-laboratory differences.
As such, it has been difficult to perform studies to ascertain the predictability of sperm morphology on outcomes. To date, no studies have been conducted examining teratozoospermia and the likelihood of achieving a natural conception NC. After the Institutional Review Board IRB approval, a retrospective chart review was conducted on all patients seen at a high volume, tertiary, academic infertility clinic from to Only live births and current pregnancies were included in the analysis.
When multiple strict morphologies, semen analyses, and hormones were obtained usually during treatment only the first, initial values were used. Strict morphology was evaluated using the Kruger strict criteria. In men who reported conception, details regarding the methodologies were ascertained i.
Data were analyzed using Student's t -test for scalar variables. A total of men who had strict morphology obtained during an infertility work-up were obtained. The average age at time of evaluation of both men and their female partners was not significantly different and neither were the average follow-up times Table 1. When examining serum hormone levels, testosterone, sex hormone-binding globulin SHBG , prolactin, and estradiol were similar among the groups Table 1.
This coincides with the inferior semen analysis findings of these men. With regard to the abilities of men to father children either current pregnancies or live births , This success was carried forward when the number of subsequent pregnancies was examined Figure 1d. Among the many factors that influence the outcomes of IVF, semen parameters have traditionally been used as an indicator for oocyte fertilization and attainment of pregnancy in addition to the quality of the oocyte.
Variability in IUI and IVF outcomes for men with teratozoospermia has resulted in controversy in how to counsel men with isolated defects in strict morphology. The evaluation of morphology is regarded as subjective due to the fact that it has to be done by the human eye.
Previously, Mortimer and Templeton 24 , 25 confirmed the existence of selection for morphologically normal human spermatozoa within the cervical mucus. Later, Mortimer 26 by evaluating sperm recovered from the cervical canal, further delineated that the selection of spermatozoa is facilitated by reductions in spermatozoa with midpiece, tail, and other morphological defects which would be expected to impair motility.
Despite their efforts and those of others, the presumed importance of strict morphology remains incompletely documented. Morphology does not indicate anything with regard to the genetic composition of the spermatozoa or the fertilization potential.
Given the controversy surrounding morphology, clinicians are left to ponder what to discuss with men who present to their clinics with poor morphology.
While this study lacks the rigor of a randomized control trial, attempts were made to limit possible bias and confounders. When considering limitations, recall bias was eliminated by the tendency of parents to remember the birthdays of their offspring. The notion that sperm morphology may not be as important as previously thought highlights how a novel systems biology approach to fertility could be considered. For example, spermatozoa remain in the oviduct for several days by binding to epithelial cells and recently, oviductal epithelial have been shown to interact with spermatozoa and protect against oxidative stress.
As such, strict morphology should not be used to predict fertilization, pregnancy, or live birth potential.

What is Sperm Morphology in My Semen Analysis — Altora Health
How does this affect my fertility? What can I do about it? Morphology refers to the shape of your sperm, or what it looks like under a microscope. Specifically, it looks at the shape of the sperm head and the size of the sperm. Sperm morphology ranges indicate what percent of sperm are considered normal in size and shape. The ranges will differ from lab to lab, depending on the criteria used to assess the sperm.
Stricter criteria will result in a lower normal range. Your doctor will discuss your range with you and help you determine what effect it has on your fertility.
According to Dr. Ten to 14 percent is still good fertility potential, 5 to 10 percent is decreased fertility, and less than 5 percent is poor fertility potential. Sperm morphology affects fertility because sperm have to be a certain shape to be able to penetrate an egg. But morphology is only one of many factors when it comes to fertility. Your doctor will also look at the number of overall sperm and how easily they move.
If your doctor tells you that you have small-headed sperm morphology, in vitro fertilization IVF may be an option. IVF is a procedure where your doctor extracts semen and injects it directly into eggs that have been removed from your partner. This is an invasive procedure, but it can be an effective method for pregnancy. Talk with your doctor if you and your partner are ready to become pregnant.
