10 Facts bạn nên biết về tinh trùng

Spermatozoon (số nhiều: spermatozoa) với tinh trùng hoặc tên khoa học đầy đủ là tế bào sinh sản thuộc cá nhân nam.

Việc sản xuất các tế bào này trong tinh hoàn bắt đầu ở tuổi dậy thì. Nó mang thông tin di truyền (DNA) rằng nó sẽ chuyển giao cho trứng trong quá trình thụ tinh trong phần đầu. Hắn có đuôi và hắn đang di chuyển. Ở người, khoảng 150-200 triệu tinh trùng được phát hành trong giao phối. Tuy nhiên, chỉ có một tế bào tinh trùng có thể fertilide trứng. Khi một tinh trùng đạt đến một tế bào trứng (oocyte), nó lá đuôi của nó bên ngoài để vào trứng và đi qua các thông tin di truyền đến trứng. Sperms được tìm thấy trong một chất lỏng dày đặc. Tên của chất lỏng này là tinh dịch (Ersuyu), ejeculate hoặc thường được sử dụng trong các hình thức của Sperma.

Người đứng đầu Spermatozois tương tự như shovel của Baker và chứa thông tin di truyền. Có một cấu trúc được gọi là Akzoroma rằng kết thúc tốt đẹp phần đầu như một nắp và chứa các enzym cần thiết cho các spermatozoside để đi qua bức tường tế bào trứng. Khi tế bào tinh trùng đạt đến trứng, các enzym trong màng acrosome được phát hành, cho phép các spermatozoa để nhập vào trứng. Số n của các vật liệu ADN Nam mà đi vào được kết hợp với một số vật liệu ADN nữ và bao gồm các con số 2n của vật liệu ADN (tế bào này được gọi là zygote). Sau đó, trong zygote, các tế bào bắt đầu nhân bằng cách chia. Các nhiễm sắc thể X và Y được thực hiện bởi Spermatozoas trong sự hình thành của giới tính là quyết định. Khi tế bào sinh sản nữ mang nhiễm sắc thể X, một nửa của các tế bào sinh sản Nam X và một nửa khác mang nhiễm sắc thể Y. Nếu các tế bào sinh sản nữ là phân bón spermatozoon với nhiễm sắc thể X, các nhiễm sắc thể trở thành XX và giới tính của cá nhân trở thành phụ nữ, trong khi đó nếu các spermatozoon mang Y là thụ tinh, giới tính của cá nhân trở thành phái nam. Tuy nhiên, có một số trường hợp ngoại lệ. như XXY, X0 cũng có thể xảy ra với các cá nhân bệnh di truyền.

Mặc dù tinh trùng được nói trong thế giới y tế, hiệu ứng của nó, lợi ích hoặc nội dung là hầu như không nói của con người. Nhưng những thông tin về nó là rất hấp dẫn. Dưới đây là 10 thông tin thú vị mà bạn không biết về tinh trùng.
