How Daily Sex Improves Sperm Quality

How Daily Sex Improves Sperm Quality1Can frequent sex improve sperm quality? This has been a debate among fertility specialists for quite a long. What doctors usually advise couples trying to conceive is to have sex every second day, so that there is time for semen to restore its sperm cells count. It is true that frequent ejaculation harms sperm count and sperm concentration as well as sperm quality are critical to successful fertilisation.

But whether that’s a proper advice for men or not, it is not quite clear. That is mostly due to lack of strong evidence suggesting that sexual abstinence can actually be beneficial to male fertility, improving sperm fertilizing ability.

In fact, a recent study led by Dr. David Greening in Sydney IVF indicates quite the opposite: daily sex is more effective than abstinence. What Sydney IVF researchers found, was that daily ejaculation for seven days improved sperm DNA quality without lowering sperm count enough to negatively affect male fertility.

At a meeting of the European Society of Human Reproduction and Embryology (ESHRE) in Netherlands, Dr. Greening explained that when a man does not ejaculate for two or three days the number of spermatozoa stored in the epididymis increases. In the epididymis spermatozoa are exposed to reactive oxygen species (ROS), thus the longer sperm cells are exposed to these molecules the greater the DNA damage of the cells. So, frequent ejaculation ensures higher DNA quality sperm.

For this study, Dr. Greening and his team collected data from 118 men with higher levels of DNA damage than normal; roughly 15% more DNA damaged sperm cells than average men. These men were asked to ejaculate daily for seven days.

Prior to daily ejaculation, scientists measured sperm DNA damage after three days of sexual abstinence. They exhibited a 34% of DNA damaged cells. After seven days of daily ejaculation, it was found that 81% of the men exhibited a decrease in DNA damage at about 12%, while for rest 19% of the men DNA damage slightly increased.

Moreover, in most of the men sperm motility was improved. Not greatly but significantly. These results accompanied by normal sperm count in terms of fertility potential. So, in all aspects daily ejaculation enhances male fertility and maybe daily sex improves sperm quality.

Apart from couples who are trying to conceive naturally, these results could possibly apply, as effectively, to couples who are in need of IVF. Men are usually called to refrain from ejaculation for three days before the IVF clinic collects their sperm sample, so many couples do not have sex frequently during the treatment.

‘’This might need to change’’ says Dr. Greening.

Anti-Müllerian Hormone: A Marker for Fertility

Anti-Müllerian Hormone: A Marker for Fertility

Many fertility specialists consider Anti-Müllerian Hormone (AMH) a reliable marker for female fertility. Actually, they can assess a woman’s ovary function or dysfunction by measuring this specific hormone.

Anti-Müllerian hormone is an essence produced in granule cells of primary, pre-antral and antral follicles in the ovary. As the follicles grow in size AMH production is gradually decreased and eventually stops. For follicles with diameter over 8 mm no hormone is produced. Due to this fact, its levels are quite stable and therefore it can be measured any day of a woman’s cycle.

How Anti-Müllerian hormone works as a fertility test

Since AMH is only produced in small ovarian follicles, its blood levels are used to estimate the size of the pool of growing follicles. As women age the number of ovarian follicles declines, so the levels of the AMH hormone decline as well. Women with many small ovarian follicles, like those with the polycystic ovarian syndrome, have high levels of AMH. On the other hand women who have a few follicles left in their ovaries, as well as women close to menopause have low levels of the hormone.

AMH levels seem to affect pregnancy chances after IVF treatment. Women with higher levels of the hormone tend to have a better response to ovarian stimulation for IVF treatment and therefore more oocytes are harvested from the ovaries. A higher number of oocytes available for IVF usually translates into higher chances of a successful outcome.

Most probably, Anti-Müllerian hormone levels do not reflect egg quality but more eggs mean more ‘’material’’ for fertility specialists to work with. Thus, it is more possible to have at least one embryo of high quality after fertilisation, available for embryo transfer into the womb.

The interpretation of AMH levels is an issue not yet resolved since it is a relatively recent test and fertility specialists have not quite agreed on what is called ‘’normal levels’’ of AMH. Even so, according to experts, if a woman’s AMH levels are low for her age is an indication of lower pregnancy chances than expected, with or without IVF.

Conclusively, each patient’s ovarian reserve status should be taken into account in order to achieve a successful outcome. Some women display a diminished egg reserve sooner than expected. The average age of menopause is 51, yet 10% of women experience absence of menstrual periods by age 45 and a low egg reserve roughly 13 years prior, at their early 30’s.

Do you think AMH test would make a useful tool for women who are still waiting for the ‘’right time’’ to have a baby?
