Infertility

The endometrium is the inner lining of the uterus. It is the tissue an embryo implants into, and the tissue from which the early placenta develops. In the first half of each cycle, it thickens under the influence of estrogen, and in the second half it matures under progesterone. A thin endometrium means a lining

Azoospermia is defined as the complete absence of spermatozoa in the ejaculate following high-speed centrifugation of a semen sample. Occurring in roughly 10% to 15% of male infertility cases and affecting nearly 1% of the general male population, it represents one of the most severe forms of reproductive failure. The term male factor infertility is

When a couple undergoes a complete fertility evaluation and every result falls within standard reference ranges, the condition is classified as unexplained infertility. Accounting for approximately 15% to 30% of infertile couples, this diagnosis can feel frustrating because it represents an absence of identifiable pathology rather than a clear structural or hormonal dysfunction. The term

Conception can be a joyous time, but it may take some couples a little time to do it. If you have regular unprotected sex and are not getting pregnant, it is important to find out the possible reasons for not conceiving and seek medical advice as soon as possible. Infertility can be due to either

A varicocele is an enlargement of the veins within the scrotum, caused by valves that no longer prevent blood from pooling. The mechanism is comparable to varicose veins in the leg. It is present in approximately 15 percent of men generally and in a considerably higher proportion of those evaluated for infertility. It is also

Sperm concentration is only one of several key parameters evaluated during a diagnostic semen analysis. A normal count is frequently interpreted as a normal result, which is why many men are told their report is fine when it is not. Fertilization depends on a sperm cell reaching the egg, penetrating it, and delivering intact genetic

Adenomyosis and uterine fibroids are two of the most common structural conditions affecting the uterus. Both can cause heavy periods and pelvic pain, and both are frequently identified during a fertility evaluation. They are, however, distinct conditions with different effects on conception. Understanding the difference matters because the treatment approach and the implications for implantation

Polycystic ovary syndrome (PCOS) is a common endocrine disorder characterized by irregular ovulation, elevated androgen levels, and polycystic ovarian morphology on ultrasound. Underlying a majority of cases is insulin resistance, a metabolic state in which the body’s cells respond poorly to insulin and the pancreas compensates by producing more of it. This compensatory hyperinsulinemia is

Endometriosis is a condition in which tissue similar to the lining of the uterus grows outside it, usually within the pelvis. It responds to the same monthly hormonal signals, which over time can lead to inflammation and scarring. The condition is strongly associated with painful periods, and that association influences when it is suspected. In

A couple goes through IVF. The embryos look good on paper, the transfer goes smoothly, and then the cycle fails. It happens again in the next round. Most of the testing so far has focused on the woman, and the man’s basic semen report came back normal. This is one of the more frustrating patterns
