Before delving deep into this topic and establishing it’s relationship with the fertility of a woman. It’s important to know, What is Biological Clock?
What is Biological Clock?
Well, the term Biological Clock evolved way back in 1970’s. It is the progression from puberty to menopause during which a woman can bear a child.
“Biological Clock” evolved when lot was happening for the liberation of women during 70’s.
- The feminist movement happened
- Oral contraceptives and intrauterine devices were developed.
- The birth rate dropped significantly
- Abortion was legalised
- Women started delaying marriage to pursue higher education and career.
The above developments gave the new found freedom to women.But then this metaphor was used to remind women to not to forget their traditional role of yearning children.
Today, the couples are not settling before late twenties or early thirties. Parenthood is embraced only after 30’s when in reality the quality and quantity of eggs are in descending order.
With the advancement of technology and Assisted Reproductive therapy women of today’s age has got the freedom to pursue their dreams and still enjoy the bliss of motherhood . Further, egg donation, embryo donation and surrogacy have given the new-age women wings to follow their dreams without worrying about their”biological clock”.
But then a body has it’s own limitations too though the technology gives you the option those procedures are time taking and expensive for sure not affordable for many couples. Many who are passionate about their dreams are freezing their eggs in the early twenties and embracing motherhood later on in their lives.Before taking decision of delaying motherhood a woman should know about her biological clock .
Four things that every woman should know about her fertility and Biological clock.
Biological Clock of a women starts ticking at the age of 30, it’s real and justified.
As women strike a new balance between education, career and relationship , many have elected to delay child bearing.
Unfortunately, the biological clock starts ticking when a woman enters in her thirties. Though she is born with approximately 2 million eggs every month she loses some hundreds. Ideally, the peak fertile period for any woman is late teens to late twenties. By the time she enters her 30’s most of her eggs are gone. Another important factor is the hormonal level that is regulated by stress, anxiety, fast lifestyle and pollution that are essential to carry so many functions.
Egg quality decreases with time.
Reasons for poor quality of eggs :
- Heavy metal contamination of food/water
In our modern-day life, these factors are almost unavoidable. Moreover, when egg remains in the ovaries for a lingering period of time it leads to genetic problems, in case if it fuses with sperm, the embryo is not of grade A. Grade A embryo leads to a healthy pregnancy. Therefore, older women have reduced fertility and exposure to high risk for the genetically abnormal fetus. Over 50% of embryos will be aneuploidy (genetically abnormal) by age 40. At 42, more than 80% of her embryos will be abnormal.
Fertility treatments can boost the chance of getting pregnant and having healthy baby.
Fertility treatments like IUI (Intra- uterine insemination ) and in Vitro Fertilization are boon to women having low count of eggs. Women suffering PCOS and non- functional fallopian tubes can opt for this treatment especially IVF where the embryo is directly transferred into the uterus.Both the treatments significantly increases the chances of conception leading to normal pregnancy.
With the advent of Comprehensive Chromosome Screening( CCS) of embryos the chances of a healthy pregnancy have increased. CCS is a process in which a physician can analyze the genetic make-up of the embryo before it is transferred thus reducing the chances of miscarriages as only healthy and grade A or B embryos are transferred. This dramatically improves the chances of delivering a healthy baby.
Fertility preservation has given the power to women to hit the snooze alarm of their biological clock.
Women are aspiring for big in life regarding their dreams and technology has given them to achieve so by successfully delaying childbirth by preserving their eggs.Oocyte(egg) freezing and Embryo freezing are two processes by which women can still experience the bliss of motherhood even in the late ’30s and ’40s. The only difference between the two is that the later one that is Embryo freezing requires sperm to fertilize the mature eggs.Both the treatment starts with hormonal medication.
Recently, the embryo freezing is most trending as the chances of live birth is much higher than egg freezing. The above two preservation methods can only be done In Vitro fertilisation treatment.
What is the right age to preserve the eggs?
The statics say that when a women is below 30 she needs 10 eggs for a live birth whereas a women at 38 would need 25 and women in their early 40’s would require probably 100 eggs for a live birth.Therefore, right age for preserving eggs will be ideally below 30 or at max before hitting 40 to increase the chances of live birth.
Technology has given wings to women to fly high and pursue their dreams. They just have to choose wisely as per their requisite. But age-factor still holds the key as in spite of egg and embryo freezing live birth rate is still at high – risk if not tried before early 30’s. Know your body before you take any decision.
