Fertility and the Role of Hormones and Passion

Couple in Love

The ability to be fertile and bear children has been seen as a blessing by God-fearing and pagan cultures since the beginning of time. Let’s take a look at fertility and the role of hormones and passion on our ability to bear children.

The Biblical Pattern

In the beginning, Yahweh’s first words to mankind contained within them an excellent tool that men and women can use to determine the state of their overall health.

“So Elohim (God) created man in his own image, in the image of God created he him; male and female created he them.  And Elohim blessed them, and Elohim said unto them, Be fruitful, and multiply, and replenish the earth, and subdue it…” (Genesis 1:27-28).

Yahweh Elohim (God) gave them a blessing, the blessing of being fruitful and multiplying on the earth.  Fertility is defined as “the property of producing abundantly and sustaining vigorous and luxuriant growth.”

Note the positive attitude that is seen toward fertility in these Bible verses: Deut. 7:12-15, Deut. 28:1-6, Deut. 30:5, 9, Jeremiah 30:19 and Hosea 9:11, 14-16.

As early as 1855, researchers began to document changes that occur each month in a woman’s body.  During the next 75 years, clues to a woman’s fertility began to open doors to understanding how hormones work in her body.  Scientists discovered that hormone levels are much more stable and predictable than they originally thought.  They also discovered that when a woman experienced patterns that were not stable, observable symptoms that she noticed in everyday life could provide valuable clues as to what was wrong.  In other words, a whole new world of hormone understanding opened up, paving the way for scientists to discover cures and treatments of problems that used to simply be thought to be “in her head.” Source: Fertility Friend.

Understanding Hormonal Fluctuations and Passion

Fertility and the role of hormones and passion…when a man and his wife understand fertility and how Yahweh Elohim (God) designed their bodies, numerous health benefits result.  First of all, they understand what “normal” is and are therefore prepared to notice when something departs from the norm.


For a man, it is normal for him to desire to be “one” (see Genesis 2:24 and 4:1) with his wife every 24-48 hours.  It is normal for him to have steady hormones and a brightly burning passion and care for his wife.  It is normal for him to desire to protect and provide for his wife and children as a result of the loving process of becoming one.  Any departure from these norms should cause him to try to find out what is wrong, whether it be in his health or in any part of their relationship.


For a woman, it is normal for her hormone levels to fluctuate over a 28-30 day period that closely approximates the cycles of the moon.  More than twelve hormones have been identified as playing a role in this cycle, but four hormones especially play a key role.

Four Key Hormones For Fertility

During a women’s monthly fertility cycle there are four hormones that are key factors in her ability to be fertile. The first half of the cycle is called the “follicular phase.”  I can easily remember this because “follicular” starts with F, for the “first” phase.

FSH: Follicle Stimulating Hormone

This phase gets its name from one of the hormones that is working very hard:  Follicle Stimulating Hormone, commonly known as FSH.  Its purpose is to prepare one of a woman’s ovaries (they generally alternate months) to release an egg from its follicle.  If FSH is not functioning properly, she cannot ovulate.  FSH works quietly, without any noticeable symptoms for the woman, but if she encounters stress or sickness during the first two weeks of her cycle, FSH will halt any release of a new egg.  It seems that Elohim has designed her body to only be fertile when she has the physical strength to sustain a new life.


Another hormone that plays a major role in the follicular phase is B-estradiol, which is in the estrogen class of hormones.  The purpose of this estrogen is to build up a healthy supply of cervical mucous.  This cervical mucous was first studied in the late 1800s, and it was noticed that the most fertile type of mucous had the consistency of egg whites.  When a man and his wife become one sexually, a man’s sperm “rides” on this slippery mucous and can reach the woman’s egg more successfully.  If a woman notices any cervical discharge that is white, creamy, or even clear, approaching the consistency of egg whites, she will then know that she is about to release an egg and is very fertile indeed.

Full Moon and FertilityFertility and the Full Moon

The full moon in the night sky has been depicted in many books and movies as romantic. Many times lovers are depicted walking outside and gazing at a beautiful full moon.  It is very amazing that women who sleep in darkness except for light from the moon will most likely ovulate during the full moon.  The reason for this is that melatonin, released by the pineal gland, will be slightly suppressed from the light given by a full moon.  This suppression of melatonin increases a woman’s  follicular-phase hormone levels and raises her chances of fertility. It is also interesting to note that the key hormones of this first, follicular phase increase a woman’s desire for her husband, making their union more pleasurable and making the conception of a baby more likely. This again validates at fertility and the role of hormones and passion are part of Yahweh’s plan from creation.

A woman can simply take note of the quantity of any cervical mucous she experiences, plus the depth of desire she feels toward her husband, during the first part of her cycle to determine if her body is preparing to ovulate.  If she lacks sexual desire, if she is not producing ample cervical mucous of an egg-white quality, or if her days are filled with extraordinary or prolonged stress, she should be concerned about the health of her body as a whole.

In the meantime, the estrogens a woman is producing are also working on the endometrial lining of her uterus, thickening it to a depth of 3-4 millimeters and turning it into a warm and inviting place for a new life to implant.

Luteinizing hormone (LH) has been quietly working in the background as well, and after an egg is released from a follicle in a woman’s ovary, LH orchestrates the production of an amazing formation of cells known as the corpus luteum.  The corpus luteum begins to secrete large amounts of a fourth hormone, progesterone.

Progesterone has been called the “pro-gestation” hormone, or the hormone that promotes life.  One of progesterone’s jobs is to increase a woman’s body temperature so that any new baby will be kept warm inside her womb.  Within hours of the release of an egg from her ovary, progesterone’s affect on her body temperature can be noticed, even if she does not conceive.  Many women check their body temperature each morning, before they rise from bed or in any other way cause their temperature to elevate artificially.  They simply reach over to their bedside tables, pop a thermometer into their mouths, and quietly doze while it records their temperature.  The morning after ovulation, progesterone will have caused a temperature elevation of at least four-tenths of a degree above what it averaged during the follicular phase.

Progesterone will remain active, continuing to keep her body warmer, for a very consistent period of 12-16 days in a non-pregnant woman.  If a woman tracks her morning body temperature (also known as a basal body temperature) consistently, during each day of her menstrual cycle, she will be able to easily see if she is producing adequate amounts of progesterone to sustain a new life.  If she happens to notice a cycle in which her temperatures remain elevated for an extended number of days, usually longer than 18, she will also know that she is pregnant.

Yahweh, the Creator of the Universe, designed our bodies to be fruitful and He declared that we should multiply and continuously replenish the earth. It is His plan for men and women to be fertile and to bring forth children that they will teach His Word and together as a family Walk in His Ways (Deut. 6: 4-9).
