Males have sperm cells and females have egg cells.
Males have testes and females have ovaries.
Males have to produce their sperm and females' eggs are already produced during fetal development.
Males have a penis, obviously, and females a vagina.. Again, obviously lol.
Males and females have different sex hormones as well.
The differences between the female and male reproductive systems are based on the functions of each individual's role in the reproduction cycle. A male who is healthy, and sexually mature, continuously produces sperm. A woman's ova (eggs) are completely formed during fetal development.
At about 5 months gestation, the ovaries contain approximately six to seven million oogonia, which then go through meiosis (Dictyate in meiosis prophase I until ovulation, halted in metaphase II until fertilization.), and are matured into oocytes.
The ovaries of a newborn baby girl contain about two million oocytes. This number declines to 300,000 to 400,000 by the time puberty is reached. On average, 400 oocytes are ovulated during a woman's reproductive lifetime.
When a young woman reaches puberty around age 12 or 13, an ova (one of the matured oocytes) is discharged from alternating ovaries every 28 days. This continues until the woman reaches menopause, usually around the age of 50 years. Occytes are present at birth, and ages as a woman ages. This may be one reason older women are more likely to have a hard time becoming pregnant or more likely to have children with genetic defects.
Well, Ummmm, let me see now, just how old are you to have to ask this question. Men have an organ called a Penis that produces a means for sperm to reach an egg in a woman's Vagina. The woman have Ovaries that produce this egg. The results of this union, most times, result in a fetus to grow in the woman's womb and eventually, after about 9 months, a baby is born.
Is this serious enough for you ?
Men are from mars and women are from Venus.
