Thanks for clarifying, since your continued participation might have fooled me.
You say this despite not being able to say what these biological differences are.
Biological women have vegina
Biological men have penis
Biological women get menses, and can get pregnant and giving birth
Biological men do not get menses, and they can not get pregnant
Difference in Biological men and Biological women about ferility
Men are continuously fertile from puberty to almost up to 100 years of age even though by that time they are physically unable to engage in sexual activities. Their sperms are still viable but poor in quality. Men are fertile this long because there is a continuous production of sperms through the process called
spermatogenesis. The process begins with germ cells which are essentially immortal. The cells are haploid since they have only half the number of chromosomes, 23 in this case. In the male all of these cells are not used at once during the reproductive process, only some will become a mature germ cell to compete in the arduous task of uniting with a female germ cell, an ovum.
Women are fertile for roughly 12 hours each month from menarche up until they are in their fifties when menopause begins for most women. Fertility for them are limited because they have a set number of eggs. During fetal development there are initially 3 million to 4 million follicles or eggs present but through the process of apoptosis (cell death) that number drops to about 1 million eggs by the time of birth. This cell depletion will continue throughout the female's life. By menarche there are only 500,000 eggs available to continue this monthly cycle for the next five decades until menopause. After about 50 years a women releases about 7,000 eggs and only 1 in 12 is available for fertilization while the remaining approximately 492,000 eggs that are never released for fertilization go to waste.
Biological women have much more estrogen than biological men
Biological men has much more testosteron than women. And because of that men has different looks than biological women and men is much stronger than biological women
The obvious physical differences between the sexes are influenced by the quantity of androgens and estrogens, two chemicals from the steroid family of chemicals, released into our bloodstream. The biggest differences occur during the development of our secondary sex characteristics beginning at puberty. We know what they are and I will not go into any details about them here.
All the sex hormones in men and women originate from acetate and cholesterol molecules present in their bloodstream. The estrogens present in both sexes, more so in women than in men, are produced from the chemical breakdown of testosterone which is also present in the blood of both sexes. In case you didn't know testosterone is produced in both the testis and ovaries because the testis in the human male were once ovaries during fetal development until a chemical in the male body triggers the sequence to cause them to descend to the lower level into the scrotum to become the testis.
Estrogen plays a critical role in our growth rate during puberty. It controls the growth of the cartilage and bone tissues. The rapid growth spurt generally occurs in girls earlier than in boys when they reach puberty due to the higher level of estrogen in the female body. This is why girls are taller than boys in the first year or so as teens. Boys catch up later in height.
Estrogen also has a strong influence on the cardiovascular system. Estrogen decreases the incident of heart attacks, kidney diseases and other cardiovascular ailments in women since they have more of it than men. However, that benefit in women disappear once they reach menopause since estrogen level drop and their testosterone level go up. Decrease in estrogen level in both sexes causes an increase in the incident of osteoporosis or bone loss since estrogen controls the rate of bone loss and resorption of calcium to produce bone tissue. When estrogen level drops the rate of bone loss is greater than the rate of bone resorption and the problem is worst in women since their bones are generally less dense than men.e testis make about 7 mg of testosterone a day and 1.75 mg of it is converted to small amounts of estradiol present in the blood of men while the ovaries in women only makes about 0.3 mg of testosterone and a little more than 0.15 mg of that is converted to estradiol. As we can see here it is the ratio of testosterone to estradiol and the potency of the two hormones that make the big differences between the sexes. Estrogens are 1000 times more potent than testosterone. The ratio of the amount of testosterone to estradiol found in men is 3 to 1 while the ratio of these two hormones in women is 1 to 1. Also, men make about 20 times more testosterone than women but the amount of testosterone converted to estrogens in women is 200 times more than men. It doesn't take much of either of these hormones to change the physical appearance of each sex to its opposite appearance.
Different chromosome between biological women and biological men:
chromosome pair 23, XX for female and XY for male, the differences between the sexes are apparent. The "Y chromosome" is much shorter than it's corresponding "X chromosome". Despite its size the "Y chromosome carries two of the most important genes for a male. One of these genes is called SRY that determine the maleness of the human species
The other genetic difference between the sexes are the inheritance of the mitochondrial DNA in the female. Mitochondria are present in all the cells of both sexes but are passed from one generation to the next exclusively through the mother. The genes they carry are replicated and do not go through any recombination as the rest of genes do during fertilization. Maternity testing is based on this knowledge of the mitochondrial DNA properties. Paternity testing is generally performed using the nuclear DNA present in all non-reproductive or somatic cells
