Women who are interested in getting pregnant after menopause have a variety of options available to them. These include egg freezing, fertility treatments, and donor eggs.
Menopause is a natural biological process that occurs when a woman’s ovaries stop producing eggs. It can cause a number of changes in the reproductive system, including a decrease in fertility.
What is sperm?
Sperm are tiny cells that carry chromosomes to an egg and help to fertilize it. They are produced in the testicles and take months to mature fully. They have three distinct regions: the head, midpiece, and tail. The head carries the nucleus, which has DNA; the midpiece contains organelles that provide energy; and the tail propels them through semen. Mature sperm measure just under half a millimeter in length and are too small to be seen without a microscope. They have a tadpole-like shape with a bulbous “head” and a narrow tail (Dcunha, 2022).
Once the sperm is ejaculated, it will be carried through the fallopian tubes to the woman’s uterus. There, if the conditions are right, it will enter her body through the cervix and into her womb.
Outside the body, sperm only live for a few seconds to a few hours. They are broken down or reabsorbed. In order for them to survive, they need lots of high-octane fuel, like sugar, which they get from the seminal vesicles. They also rely on fluid from the prostate to cause semen to liquefy, which allows them to swim.
A man’s testicles are basically sperm factories, producing around 50-100 million viable sperm per day. The process of sperm production is known as spermatogenesis and begins at puberty.
How does a man make sperm?
Men make sperm in their testicles (also known as the two testicles or the seminiferous tubules) which produce a fluid called seminal plasma that transports them. The process of making sperm is called spermatogenesis and it begins when the hypothalamus in the brain releases gonadotropin-releasing hormone, which travels through the blood to the anterior pituitary gland and encourages it to release luteinizing hormone (LH) and follicle stimulating hormone (FSH).
When LH and FSH meet with testosterone in the seminiferous tubules, they trigger the body to produce androgens such as DHT, which promote sperm production. The sperm cells then move from the testicles to the epididymis, which is a storage vessel where mature sperm are stored until needed for fertilization.
Mature sperm have three parts: the head, which is shaped like a teardrop; the midpiece or neck, which contains mitochondria that generate energy for the sperm cell; and the tail, which has flagella that allow the sperm to move. The tail also has a special protein that helps it penetrate the egg’s outer membrane and fertilize it.
Once a man ejaculates mature sperm, they are in a race to reach the egg. They must avoid the acidic environment of the vagina, which can kill them; and they must pass through any cervical mucus that may slow or block their path. It takes about 74 days for a sperm to complete its journey to fertilize an egg.
How long does sperm live in a man’s body?
Sperm need a wet environment to survive. If they end up on dry surfaces like bed sheets or clothing, they will die unless they can get wet again quickly. They may survive on skin for a few minutes, but they won’t be able to fertilize an egg.
Spermatozoa are typically stored in the epididymis, which is a reproductive organ inside the man’s scrotum. They can stay alive there for several days if conditions are right. Sperm can also be frozen and kept indefinitely if it’s done properly. To be effective, freezing sperm requires an accurate temperature and a controlled laboratory environment. The average household freezer can’t handle this type of extreme cold, so sperm is typically cryogenised and stored in a sperm bank.
Once sperm are released by the man, they have about an hour to travel from the testicles through the epididymis and into the vagina of the woman where it will fertilize an egg. They can’t do this in a bathtub or pool, as the disinfectant chemicals and the high or low temperatures will kill them.
Depending on their health and environment, sperm can last up to five days after being released by the male body. They need this time to reach the egg, which is why many couples only use sperm for a few days after sexual intercourse.
Can a man get pregnant after menopause?
Menopause is the end of female reproductive capability and typically occurs in middle adulthood. It may be delayed in some women who have specific health issues or are undergoing medical treatment. Many women decide to start families later in life and this can influence birth control choices and when they try to conceive. Some women may have difficulty conceiving during the transition to menopause, which is called perimenopause and can last from eight to 10 years before a woman reaches menopause.
During perimenopause, estrogen levels decrease and the menstrual cycle becomes irregular. This can make it difficult to know whether a woman is ovulating or not, but pregnancy is still possible. Women who are trying to conceive during this time should use contraception until they have gone 12 months without menstruating to avoid unintended pregnancy.
Once a woman reaches menopause, she is no longer ovulating and her hormone levels are not sufficient to support pregnancy. However, in some cases, pregnancy is possible after menopause, particularly when a woman uses hormonal therapy or sperm from a donor. Some women have even had successful pregnancies after having their ovaries removed by hysterectomy. During a hysterectomy, an egg is sometimes left in the abdominal cavity and sperm can fertilize it. However, this is very rare and requires careful planning and expert care.
